  2. oslomike, I, too, don't have any knowledge of "inexpensive data recovery companies in the UK that specialise in tape recovery". However you could easily get a quotation from this company, using the form on the web page. It sounds as if they might have special software that can copy your one AIT tape and put a proper end-of-file marker on the copy, if that's what you want to know about.

  4. Then, tbh, you need a better system for archiving that data. Like with backups (and I draw a distinction between archive and backup), you should be thinking "3-2-1" -- 3 copies on 2 different media with 1 offsite and, importantly, you should be rotating your archives on to new media more often you have been. High-resilience disk-based storage is relatively cheap and you should use that for your "primary" archive copy. Don't forget to check application versions etc -- you may be near the point where you'll need to re-write old data to new formats... I wouldn't know -- and I'm not sure I'd trust anything over Retrospect for recovering RS's proprietary format (tar tapes would be a different matter). Best to avoid any problems with "3-2-1", media rotation, regular checks that you can retrieve files, and so on.

  6. Hi Nigel! Thanks for your insight on what you think is best. It does seem like a good way to go. As you said, It'll probably take longer to get them combined but I think I''ll try that. It's worth a try. You mentioned if it's worth to keep old archives, in my case, the data from 10 year back in time are all multitrack music productions I've worked on, and I'm being surprised all the time by people asking if I can make a new version of a song for a film or something similar. Lucky them I have the archives, though it's not my responsibility. BTW, are there any inexpensive data recovery companies in the UK that specialise in tape recovery? I'm just wondering in case I ever need to get data off a tape that has problems. We have one here in Norway, but it's expensive.
  7. Don't know about best, but what I'd try is: Rebuild to "tapeset1", starting with the first tape, expecting it to fail at the end of the tape as you've described Rebuild to "tapeset2", starting with the first tape, expecting it to fail... Take tape 1 out of the drive! Repair "tapeset2" and, when it says insert tape 1, mark tape 1 as missing and continue with tapes 2 and 3 You've now got the most data back that you can, albeit in two sets. You could then try and combine them by copying "tapeset1" to a new "diskset1", then "tapeset2" to that "diskset1" -- "diskset1" can then be moved to your newer machine for the conversion. Your choice as to whether "diskset1" is a File Set or Removable Media Set. You could, perhaps should, copy the two tape sets to two disk sets, convert them to the new format, then combine them -- it'll take longer but might be "safer". I'd also start to wonder about the chances of me ever needing to go back to data from 10+ years ago and whether it's worth all this extra work! That'd be a struggle between my innate laziness and my OCD, but you may have compliance issues to satisfy.
  8. I won't claim it's best -- but it's what works for me! Meanwhile, I've run some tests -- and I am getting snapshots transferred in a v6 File Set conversion. Couple of wrinkles: The File Sets were created in RS v6.1.230 rather than transferred from tape The conversion was done with RS v13.5 -- the closest I have to v10 on hand Only one snapshot is shown in the rebuilt set until you go to "Media Sets", select the rebuilt set, select the "Backups" tab, and use the "Retrieve..." button to show the others. Alternatively you can use the "Restore" wizard, select the single-snapshot set, and use the "More Backups..." button to show the other snapshots. So the snapshots are transferred. Whether that's because I'm using a different converting version of RS, a different workflow, or just delving deeper into the end result to find them -- who knows?
  9. It means those files were changed in between the time they were backed up and the time they were compared (the version still on disk and the version in the backup). It seems as the user was (actively) using the Photos application during the backup process. I shouldn't worry about that.
  10. I have a questions regarding the use of SQL databases backed up through Retrospect. Quick questions: What is the actual format of the retrospect backup of the database? Does Retrospect actually generate a .BAK file of the database? Can these be provided as databases to be imported to a new hosted system? Long explanation of the ask: I am backing up a SQL 2012 database for our internal ERP service using Retrospect 17.0.2.102. SQL Agent. We are planning on moving this service to a new server hosted by the ERP vendor. For our vendor to set up the new server, they require a backup of our current database. However, our install of SQL Server Management Studio just started giving us a licensing error and will not launch to allow us to export the database, and the SQL Server Management Studio stopped working. We are concerned about trying to resolve the licensing error by uninstalling/reinstalling the software without current backups, so a "Perfect Storm" of problems. Talking with the ERP vendor, they asked if we can provide a backup file from a different backup solution for them to use. If the Retrospect backup would work, we could simply use that to set up our new server, and not worry about resolving the licensing issue on a server that we are planing on retiring anyway. So, while we are backing up through retrospect, I am not sure if the backup format is correct, and if it is, how I could provide it to the vendor. Any assistance or advice is appreciated. Don
  11. Thank you both for the help. @DavidHertzbergI didn't realize those sources options were there. I changed to startup volume and also enabled wake-on-LAN and encrypt link. Not sure what the "didn't compare" error signifies but looks like the initial problems are resolved. --Log-- + Normal backup using Laptops at 1/13/2021 12:29 PM (Execution unit 1) 1/13/2021 12:29:26 PM: Finished scanning backup set data files To Backup Set Laptop Backups... - 1/13/2021 12:29:26 PM: Copying Macintosh HD on SAR MacBook Air 1/13/2021 12:49:28 PM: Found: 1814840 files, 252742 folders, 185.9 GB 1/13/2021 12:50:23 PM: Finished matching 1/13/2021 12:51:00 PM: Selector "All Files Except Cache Files and Backblaze" was used to select 1674396 files out of 1814840. 1/13/2021 12:53:05 PM: Copying: 485 files (1.8 GB) and 0 hard links 1/13/2021 1:09:59 PM: Building Snapshot... 1/13/2021 1:10:00 PM: Checking 252742 folders for ACLs or extended attributes 1/13/2021 1:29:33 PM: Finished copying 31719 folders with ACLs or extended attributes 1/13/2021 1:29:43 PM: Copying Snapshot: 2 files (507.3 MB) 1/13/2021 1:29:48 PM: Snapshot stored, 507.3 MB 1/13/2021 1:29:48 PM: Comparing Macintosh HD on SAR MacBook Air *File "Macintosh HD/Users/srubin/Pictures/Photos Library.photoslibrary/private/com.apple.photoanalysisd/caches/graph/CLSContactCache.sqlite-shm": didn't compare *File "Macintosh HD/Users/srubin/Pictures/Photos Library.photoslibrary/private/com.apple.photoanalysisd/caches/graph/PGCurationCache.sqlite.sqlite": didn't compare *File "Macintosh HD/Users/srubin/Pictures/Photos Library.photoslibrary/private/com.apple.photoanalysisd/caches/graph/PGCurationCache.sqlite.sqlite-shm": didn't compare *File "Macintosh HD/Users/srubin/Pictures/Photos Library.photoslibrary/private/com.apple.photoanalysisd/caches/graph/PGCurationCache.sqlite.sqlite-wal": didn't compare *File "Macintosh HD/Users/srubin/Pictures/Photos Library.photoslibrary/private/com.apple.photoanalysisd/caches/graph/PhotosGraph/construction-photosgraph.kgdb": didn't compare *File "Macintosh HD/Users/srubin/Pictures/Photos Library.photoslibrary/private/com.apple.photoanalysisd/caches/graph/PhotosGraph/construction-photosgraph.kgdb-shm": didn't compare *File "Macintosh HD/Users/srubin/Pictures/Photos Library.photoslibrary/private/com.apple.photoanalysisd/caches/graph/PhotosGraph/construction-photosgraph.kgdb-wal": different data size (set: 955872, vol: 1911712) 1/13/2021 1:30:29 PM: Execution completed successfully
  12. Thanks Nigel, I'm interested in learning more about what works best.
  13. I tend to play it safe, and create the new media set myself rather than relying on the software -- mainly because it gives me extra chances to check the name, settings, etc! Finally got to go in to work this week, so I've fired up the old v6 server and I'll do some test wrt snapshots and the v6 set conversion.
  14. That log actually suggests that the scan is failing during the "SAR MacBook Air" operation because of a network disconnect and it then can't access the other APFS volume groups because the laptop isn't on the network -- they're a symptom, not a cause, so omitting them won't help. Solve the network problem. I'd start by defining a small "Favourite" folder, seeing if that works, then expanding. It might be a time-based issue, eg aggressive sleep settings, maybe a dodgy drive, or something else -- so I'm afraid you've some troubleshooting ahead...

    Retrospect 7.7: Recovery with backup-media

    My pleasure. Off topic: Swedish is my native language, I know English quite well (including SOME differences between British English and American English) and I studied German in (elementary and high) school for five years in the seventies. But since I don't practice German on a regular basis, I have forgotten most of it. Oh, I made a business trip to Paris (France, not Texas ) in 2000 so I learned to SAY two sentences in French: "I don't understand. Do you speak English?" But DON'T ask me to SPELL it in French.

    Ignore Preboot, Update and VM?

    denno, I don't use Proactive scripts; just ordinary Backup scripts. My MacBook Pro "client" is also still booting macOS 10.13 High Sierra, whereas you're probably booting a more-modern version. However I have one suggestion that has worked for me. In the Sources category entry for "SAR MacBook Air", click the Options tab and look at the Back Up pop-up menu on the lower-left of the panel. You probably want to set that pop-up to Startup Volume. If you want to try backing up the "VM" and "Client" and "Update" volumes on "SAR MacBook Air", you could instead try setting that pop-up to Selected Volumes and check-marking the volumes you want to back up. If neither of those settings works, you might be able to solve the problem if you are willing to wait to back up "SAR MacBook Air" until you have plugged it into an Ethernet cable connected—directly or indirectly (through a switch) to your LAN router. You would get its MAC address in About This Mac->System Report->Ethernet->(select card if you have more than one), and create a fixed IP address (some people call that a static IP address) for that MAC address in your router; the method for doing that varies with the router brand and model—ask the ISP that "gave" it to you. However if you insist on having a "poor wandering laptop" connecting to your LAN only with WiFi, you could try either of the two approaches in this post in the Windows–Professional Forum. As Nigel Smith points out in the post directly below that one, they work for a macOS "client" even though they don't work for a Windows "client". After a number of posts discussing the -530 problem for Windows "clients", I said in this post that I had filed Support Case #75559 embodying my suggestions. Feel free to mention it by number in any Support Case you file; Retrospect "Inc." is darned well going to have to solve this problem when they release Retrospect 18.x with the option for a StorCentric Drobo/Linux "backup server" in Spring 2021. P.S.: I had thought about what Nigel Smith says in the post directly below, but had decided "Nah, Denno couldn't be having connection problems after his/her laptop triggers its Proactive script". I thus violated one of my rules for answering Forums questions, which is to look at the administrator's past posts. Lo and behold, this OP about 8 months ago says "All 3 computers are on my home wifi network". Denno should try what Nigel Smith suggests, then start a thread in this Ars Technica Networking forum. Warning: Those experts will be rough on any poster who doesn't supply complete information, so Denno shouldn't try to pull any of the "I don't want to supply complete information because ... security ..." or "I don't want to supply complete information because my employer/clients might recognize me" stunts administrators try to pull when posting in these Forums.

    Retrospect 7.7: Recovery with backup-media

    mcmeini, What I've called the squeaky-clean approach to locating Members of a Backup Set—which you've evidently now followed and which Lennart_T understands—is described in the second paragraph of this post in a Retrospect Mac 9+ Forums thread. Just ignore what I said about the zero-byte "marker" file; further experiments per the first paragraph of this post further down that thread showed that the "marker" file has only a very restricted purpose. That purpose is to exclude destination Members from a Backup or Duplicate operation; they should be copied with Transfer operations. That post further down that thread, and the post below it, describes non-squeaky-clean approaches which my experiments show administrators can use for Member destination positioning. It's unfortunate Retrospect Inc. never put a thorough explanation into the User's Guides. BTW, Lennart_T, how many languages do you speak? I'm impressed. 😀
  18. Hi David, The tapes are definitely AIT-2 tapes and were created is in 2006. I'm almost completely sure that they're v6 Media Sets from my old mac that ran v6 for many years. Right around this time, ca 2006, I had a very unfortunate break-in at work right when I switched computers for the backup machine and the old computer with all of the v4 and v5 catalogs was stolen. Fortunately, I was smart enough to back up "most" of the catalogs on that machine and put them on a newer system backup. I used v6 for a long time, and was kind of late to migrate to v8. I didn't migrate to v8 until about 2010 and that's when I started using LTO. I had a very unfortunate break-in at work right when I switched computers for the backup machine and the old computer with all of the v4 and v5 catalogs was stolen. Thanks for sharing the story about ITT tape systems, interesting read. 🙂

    Thank you very much. That was the error. Funny that retrospect doesn't say the user which level of the hard disk it needs. Thank you so much.

    Retrospect 7.7: Recovery with backup-media

    It might be that you are one folder level too deep. Go up one level, so "1-Daten Wochentlich-Ung" is in the (now) empty list. Select it and then click "OK" (not "Öffnen").
  21. oslomike, Was the Tape Backup Set that contains the "bad" tape originally written with the Exabyte drive? I'm guessing that this may be so if the Backup Set was created by v4 or v5; the timeline of Retrospect Mac releases at the bottom of this Retrospect History article versus the Wikipedia timeline for the release of AIT-2 seems to show that a Backup Set written up through 1999 couldn't have been written on your AIT-2 drive. Therefore, if you still have it lying around, I suggest you try re-reading the tapes in that Backup Set using your old Exabyte drive. I'm not an expert, but differences in mechanical skew between drives can make tapes written on one drive hard to read on another—especially for special characters such as end-of-tape markers. Let me tell you a tape story: In 1969 I was working as a programmer at ITT Data Services in Paramus NJ, and my boss asked me to write a program to read "gapless" tapes on the IBM S/360 DOS computer at our satellite Lakehurst office and copy them to ordinary "gapped" tapes. The "gapless" tapes were being written by the U.S. Navy's Lakehurst Naval Air Station (that's where the Hindenburg dirigible caught fire in 1937), using a tape drive attached to a radio-telemetry receiver that had no ability to store received data while an inter-block gap was being written. LNAS could read these "gapless" tapes using a Control Data minicomputer connected to a special tape drive that could somehow "stop in less than 2 inches and navigate backwards to before the stop", but the minicomputer had such a pitifully-small main memory (4K 12-bit words) that the LNAS engineers (testing top-secret aircraft; don't ask 🙄 ) couldn't do any real analysis on it. The engineers wanted ITT to copy such tapes onto "gapped" ones that could be read by an ordinary tape drive on one of ITT's 512KB OS/360 IBM mainframe computers in Paramus. I wrote a tricky copy program in S/360 DOS Assembler, and it worked successfully on a test tape. However it turned out that the LNAS tape drive attached to the radio-telemetry receiver had a skewed read-write head, and the Control Data minicomputer's tape drive read-write head had been skewed to match. ITT wasn't willing to skew one of its satellite-office IBM tape drives to match, so my program never got used in production. See an audio expert for an explanation of tape skew.
  22. Dear forum members! I have a problem with Retrospect 7.7 Professional, which I use several years and never needed it really to recover data, because I have a RAID mirror with 2 disks in my desktop computer. In December 2020, one hard disk in the desktop computer failed and have completely destroyed. Then I ordered a new one to replace the destroyed hard disk to have the mirror again. But then the corona lockdown in Austria came and since then I couldn't buy a hard disk at my local shop. I thought the remain hard disk will not give up until I get the new one, but today it does. Now I tried to use my notebook to build up the backup-set with the backup-media, but retrospect couldn't find any file on the backup-media (external USB 3 hard disk). When I open the external backup hard-disk, it seems that there are no files in the "Retrospect" folder (see attached picture). I have two backup-media, one for odd weeks and one for even weeks, but with no one I can build up the catalog file. I do every week with one media a normal backup. Because I wanted to be prepared for this case that both hard disks give up, I checked the week before with retrospect function "verify media" if both external backup-media are allright and retrospect doesn't found any error. Do someone know what I do wrong or why it doesn't work? Thank you very much
  23. Hi, So sorry for all the confusion! I DO appreciate all the help and would hate to stir up any bad feelings. 🙂 I have multiple parallel challenges I'm facing and it's hard for me sometimes to organise it myself. In regards to this thread to which I'm replying, I'm having an issue with the first AIT-2 tape of a 3-tape Media Set (Media Set was created using Retrospect 6). The system that was running the rebuild at the time of the "replace media" problem consists of a 5,1 Mac Pro High Sierra. The only tape drive connected is an AIT-2 via firewire. The version of Retrospect is v10.5. (An extra challenge I'm having with this machine is that I cannot get the Retrospect Engine to quit, but I won't get into that now). So after the above mentioned AIT-2 tape encountered some error at the end of the catalog rebuild, I was able to STOP the Retrospect process and it saved the contents of that first tape as a Media Set catalog. I don't find any snapshots but I can search for files and folders. What would be very nice is if I can continue rebuilding that catalog starting from the second tape but keep the contents of the first tape in the catalog. Here is where it starts to get confusing: Sitting next to my 5,1 Mac Pro is my 2,1 Mac Pro . It has an ATTO SCSI PCI card connected to it and hanging off the card is an Exabyte tape drive. The Macpro 2,1 is running Retrospect v6.1. There are times when I also connect the AIT-2 drive to this 2,1 Macpro in order to recatalog any AIT tapes that were created with earlier versions of Retrospect (v4 and v5), which the 5,1 Macpro setup won't read (v10.5 reads v6 but nothing earlier). The 2,1 macpro runs v6.1 and it quits just fine. So, back to the original problem of this thread, is there a clear best choice of paths to take to both recatalog and copy the data off the "bad" tape? I understand the different scenarios you mentioned above, I'm just hoping I might get a little guidance as to what to try first, now that you hopefully have a clearer picture. In regards to older posts about an old Leopard running Mac, I have always used the same drive, or same drive model (I usually keep a spare for when one goes down.). I've never had any problems with reading or writing with the AIT drives and all the data I've retrieved is very well preserved and not much fuss, BUT I have had those drives do some nasty things to the tapes themselves (cut/crunch/twist). Interestingly, my Exabyte tapes are nearly flawless, both mechanically and data integrity wise. I'm really sorry if I'm not as clear as you'd like, I use a lot of time writing these posts, as I I'm sure you do as well, and I apologise if I seem unappreciative. I'm very happy to get help. Thank you.
  24. I've tried everything I can think of to get Retrospect 17.5.2 to stop trying to back up the Preboot, VM and Update volumes because I get a client not found everytime my Proactive backup runs (example below). I have tried removing those volumes from the list of Sources but they reappear. I have also tried excluding them via Rule to no avail. Is there a way to do this? example log file- + Normal backup using Laptops at 1/12/2021 8:14 AM (Execution unit 1) 1/12/2021 8:14:18 AM: Finished scanning backup set data files To Backup Set Laptop Backups... - 1/12/2021 8:14:18 AM: Copying Macintosh HD on SAR MacBook Air [*] soccRecv: recv failed, error 60 Scanning incomplete, error -559 (network connection timeout) [*] mltrScanBad: @ fileCount=401947 folderCount=44020 treeMemSize=134408680 normSpaceCount=2 spanSpaceCount=0 dirMemSize=16965968 Can't access backup client VM on SAR MacBook Air, error -530 (backup client not found) Can't access backup client PreBoot on SAR MacBook Air, error -530 (backup client not found) Can't access backup client Update on SAR MacBook Air, error -530 (backup client not found) 1/12/2021 8:20:32 AM: Execution incomplete
  25. oslomike, Lennart_T is correct; neither your OP or subsequent posts made it clear that you were encountering the problem with the tape during a Rebuild of a Catalog for a AIT Tape Backup Set—I thought it was during a Transfer of that Backup Set to a v6.1 Backup Set. I also thought you were having this problem using Retrospect Mac 6.1 on your old Mac Pro (2,1). It wasn't until I read this recent post in one of your other threads that I realized you have connected your Exabyte AIT tape drive to your newer Mac Pro (5,1), so you are encountering these problems running macOS 10.13 High Sierra—as you've said in a recent post in the second of your other threads. Naturally the suggestion now occurs to me that you should move your AIT tape drive—and the ATTO SCSI PCI card it's connected to—back to your old Mac Pro (2,1), and try Rebuilding the lost Catalog for that AIT Tape Backup Set on your old machine. If you can do so including the "bad" first tape (which might only have a bad end-of-data marker when it is read by Retrospect Mac 10.5 under High Sierra; there could have been some limitation in the AIT-drive-handling code), then do a Transfer of all 3 tapes to an LTO Tape Backup Set on the old machine, and copy that complete LTO Tape Backup Set on the new machine—to an LTO Tape Media Set. If OTOH you still get the error on the "bad" tape, then temporarily postpone copying the "bad" tape by doing what I said in the second paragraph of this up-thread post—with the Transfer of the incomplete AIT Backup Set being to an LTO Tape Backup Set . After drafting the above paragraphs I went to dinner, and came back to find you had made another post (up past your Norwegian bedtime, aren't you? 😲). Frankly I'm getting rather annoyed, oslomike, with your systematic refusal to clarify in this thread which of your two machines you're talking about. 🤢 I'm here to help you, not to play guessing games. Returning to the final sentence of my third long paragraph above—if the AIT tape turns out to be "bad" when read on both machines, you could later do one of two things to accomplish what you're asking Lennart_T how to do in the third sentence of the post directly above this—depending on whether Retrospect will quit when run on your old Mac Pro (2,1). If it will quit on your Mac Pro(2,1), mark the "bad" tape as Missing from the AIT Tape Backup Set per "The Members Tab" on page 155 of the Retrospect Mac 6 User's Guide and then Rebuild that Backup Set's Catalog with the "good" tapes per "Rebuilding a Catalog"on pages 188–189 of the UG. Alternatively you could try the "Verifying Media Integrity" operation on pages 190–191 of the Mac 6 UG. If it won't quit on your Mac Pro(2,1), first quit the Retrospect Engine on your Mac Pro(5,1) or uninstall it—after making a Finder-copy of the files that are in Library->Application Support->Retrospect , then re-install if necessary—followed by a reverse--Finder-copy of the copied files back into Library->Application Support->Retrospect—and follow the "Verifying a Media Set" procedure on pages 208–210 of the Retrospect Mac 10 User's Guide—doing a Mark Lost for the "bad" tape. After that follow the "Repairing a Media Set" procedure on pages 210–213 of the Mac 10 UG, clicking the Add Member button for each of the "good" tapes—this may not work unless you click Add Member twice to skip over the "bad" tape. This 2012 OP of yours raises a new set of questions because it says "I have this old Exabyte Mammoth LT drive", and the Exabyte Mammoth LT has only SCSI connectors. Yet this very recent post of yours says "I just brought the AIT drive home and it connects via firewire cable". This later 2012 OP of yours says "Retrospect v6.1 on one partition with Leopard running which will be mostly used for a SONY AIT-2 (firewire interface) and an older Exabyte Mammoth LT drive (SCSI 1 interface via ATTO UL5D card)." Does that mean the "bad" tape was written on a different AIT tape drive from the drive on your Mac Pro(5,1) which had trouble reading it? And this CNet page says the interface on the Sony AIT e200-UL is FireWire 400, which means—I also have a Mac Pro (5,1)—that you must be using a FireWire-400-to-800 adapter. Hmmm! 🤔
  26. Hi Lennart, Thanks for the clarification. That makes sense. As far as marking a tape as missing, Retrospect didn't give me that option to continue the process in any way. Can I repair this particular catalog by somehow forcing Retrospect to continue cataloging from the second tape? Seems that when I tried to do a rebuild, it asks for the first tape. I haven't tried repairing starting with the second tape, but I'm curious as to what will happen.
  27. I think David meant source tape and destination tape, respectively (during the copy operation). MY point was to mark tape 1 as missing during (or before) the recatalog operation. I'm sorry I didn't make MY point more clear.
  28. Hi Lennart, I don't totally understand the what you mean by input and output tapes. In this process I'm speaking about in the orig post, I'm doing a recatalog because the original catalog is lost. So, I don't have the data off the tape yet, just trying to catalog it first.
