  1. About 6 weeks ago I started getting -559 network connection timeout errors after about 2 hours while running my weekly "Sat. Backup" full backup of my MacBook Pro (the first of 3 drives plus a Favorite Folder backed up in that script). There had not been any change in any of my software or hardware, so I guessed that at least one of my two Netgear Gbps Ethernet switches was starting to feel its age. I replaced both switches with non-Netgear 100Mbps switches I had lying around, and the problem went away—without slowing anything down except (moderately) the MBP's Compare phase of "Sat. Backup". Since NewEgg was having a US$15 sale on TP-Link 8-port Gbps switches (Heavens to Betsy, my home LAN is becoming obsolete because I'm not upgrading it to 10Gbps ), I ordered a pair of them. Even though replacing both 100Mbps switches with the Netgear Gbps switches one at a time didn't cause the -559 problem to recur, a week ago Sunday I replaced both switches with the newly-arrived TP-Link Gbps switches. The -559 problem still didn't recur last Saturday, so Sunday night I went into experimental mode and Deleted-Added my MBP with Use Multicast. Both a pre-scheduled "sacrificial" "NoOp Sun.-Fri Backup" script and "real" "Sun.-Fri Backup" script failed with -530 errors when I booted my Mac Pro "backup server" machine after the time when they were scheduled to run. I therefore Deleted-Added my MBP with Add Source Directly, and have had no further problems. IMHO this experience proves that my -530 Bugs 1 and 2 are not caused by a "security improvement" that was made solely in Netgear's Gbps Ethernet switches. Because I started getting -530 Bug 1 immediately after I replaced the failed D-Link 100Mbps switch in my study with a Netgear Gbps switch on 30 January 2017, without any change in my then-current Verizon DSL "gateway" router, my guess is that the "security improvement" was made to several manufacturers' Gbps Ethernet switches. And no doubt there is a contributing factor of Retrospect's implementation of its Multicast feature failing to keep up with the "security improvement".

    .mkv files and backups in Retrospect v.16

    CherylB, Here's a Retrospect 8 Forum thread from early 2011 that discusses this problem. IIRC Retrospect Mac 9 wasn't released until late in 2011. A key question is whether your user's .mkv files have the .mkv extension on the name of the file. If not you've got a problem, unless you restrict what is scanned via Favorite Folders etc. as later posts in that thread suggest. BTW, this "Retrospect Mac bug reports" forum is no longer routinely looked at by anyone from Tech Support, so you might as well have posted your problem in the parent "Retrospect 9 or higher for Macintosh" forum. Besides, it seems the problem isn't a Retrospect bug so much as a Retrospect limitation—it can't tell the type of a file that doesn't have an extension on its name.

    AWS virtual tape library

    blm14, What Nigel Smith said. Let me add two pieces of information. First, it is a not-evident fact (see page 225 of the Retrospect Windows 11 User's Guide; last I heard you were still using that version) that Transfer Backup Sets operations can use Selectors. You could use Selectors in running Transfer Backup Sets operations whose source is a regular Amazon S3 bucket and whose destination is a Glacier bucket, specifying a date to separate the "archival" backups from the "recent" backups. But that would still leave you with the "archival" backups also in regular S3. It is a fact that, if you upgraded to at least Retrospect Windows 15, you could use Selectors in Grooming scripts to groom out the "archival" backups from regular S3 after you have migrated them to Glacier. This Knowledge Base article talks about using Selectors in Grooming scripts specifically for satisfying GDPR requirements, which is why the Selector capability was added to Grooming scripts in Retrospect 15. My guess is that you could specify the faster and cheaper (no Amazon download fees) Performance-Optimized Grooming in those scripts, since your grooming Selector would specify a date—not the name of an individual customer having a "right to be forgotten". In any case, my impression from this article is that you would have to have an on-premises appliance in order to use an AWS VTL. because that would require some kind of "intermediary" local storage. Since you seem to have an aversion to taking local tapes or disks off-site, how would that differ from Nigel's proposal? P.S.: Here's rforgaard's 2016 post on how to setup AWS S3 cloud backup for Retrospect Windows 11. Here's the only-slightly-later KB article; here and here are other applicable KB articles. P.P.S.: Just to make it crystal-clear, blm14, I don't think you need an Amazon VTL. Transfer Backup Sets in Retrospect Windows 11 gives you the capability to transfer "archival" backups from a local tape Backup Set directly to Amazon Glacier (after a 1-day stay in regular AWS). Retrospect Windows 15's enhanced Grooming scripts would give you the capability to keep the "recent" backups in regular AWS, without duplicating what you have in Retrospect Glacier. If you need multiple "conceptual tape" Backup Sets to keep the "recent" vs. "archival" dates straight, you'll probably have to pay for extra hardware even if Retrospect can interface with an Amazon VTL—and I don't know if it can (or needs to). P.P.P.S.: Here and here are articles discussing VTLs. The bottom of the second page of the first article discusses a solution that "is available either as a fully-built appliance or as a software component of ***'s Virtual SAN SDS solution that can run on a customer's existing hardware." The STK L700 is a physical tape library originally from StorageTek; my impression is that its instruction set is widely emulated. Again, I don't see why you can't simply run Transfer Backup Sets scripts to copy your "recent" backups to either local HDDs or regular AWS, and then run Transfer Backup Sets scripts to move the "archival" data to Glacier—followed by Grooming it from the "recent" backups.

    AWS virtual tape library

    blm14, I still suggest contacting Retrospect Sales. Did you do that, as I suggested in the P.P.S. of my preceding post in this thread? Also, I said in the P.S. of that same post, AFAIK there would be a non-trivial hardware cost; however a re-listen to the brief mention in the NB video and Google search suggests that may be replaced by a virtual appliance in an AWS EC2.
  5. I'll end my comments on the merger with a bit of pure speculation on what the synergy might be for Drobo. I found this 7-year-old blog post, briefly updated over two years ago. Its "Why I'm done with drobo" section basically says that if your Drobo box dies, you have no choice other than to replace it with another Drobo box because its BeyondRaid formatting is proprietary. In the meantime the data on the HDDs that were contained in that Drobo box are inaccessible; one commenter on that blog said 4 years ago that she couldn't get files off her crashed Drobo, a model that is out of production with no parts available, so her only option was purchasing a new Drobo model. The Wikipedia article on Drobo has the same criticism. There is one backup application whose maker partners with Drobo, but it only backs up to the cloud—which may be rather expensive for an administrator with many large files on their Drobo. So why not give Retrospect Inc., now a subsidiary of Drobo's parent company, the proprietary format for BeyondRaid—enabling backup of a Drobo to tapes or a big-but-non-RAID HDD? I'm not saying the Retrospect engineers could add this capability in a week, but they've already done the equivalent for Avid Media Composer. "And now that you've paid US$49 [ or maybe nothing—my marketing genius tendencies are telling me to double-cross the maker of the cloud-only backup application ] for your license to Retrospect Solo with Drobo Capability, how about upgrading to Retrospect Desktop Edition with Drobo Capability for another US$35?" P.S.: A Forums search indicates Retrospect has long been able to use a shared Drobo as a source, although some Retrospect Mac administrators have reported problems here and here. By a not-so-strange coincidence, a new Knowledge Base article has just been posted—whose "Retrospect Setup: Add Drobo as a Source" section consists of two YouTube videos narrated in the dulcet voice of the head of Technical Support. So my speculation about Retrospect needing Drobo's proprietary format information seems wide of the mark.
  6. henry-in-florida, Read all of my OP in that same thread. I believe it answers all your bulleted-point questions except the third one. Nigel Smith's final post in that thread recaps my experience doing a suggested upgrade from Sierra to High Sierra, but we're not sure how the Apple Support person found an installer that enabled me to do that—and we're pretty sure we couldn't find one ourselves.
  7. henry-in-florida, The bottom of this April post contains my method for fully restoring a machine after a bare-metal Erase and Install of the High Sierra OS on a MacBook Pro with an SSD. As discussed in the OP of that thread, it has been combat-tested ; I'm pretty sure it will also work for Mojave and Retrospect Mac 16. In the last post of that thread, the worthy Nigel Smith gives the method his blessing.

    Request to increase size of disk backup set is being ignored

    You can get a free 45-day trial of Retrospect Windows 16.1.2.102 here. If you talk to Sales at (888) 376-1078 or (925) 476-1030, they can probably check with Tech Support to see if that release fixes your problem—and if so tell you how much it will cost you to permanently upgrade. If it does, you can presumably find some disk drive on which to install it.

    Request to increase size of disk backup set is being ignored

    haggis999, These are simply a couple of WildA**edGuesses from a Retrospect Mac administrator: First, the cumulative Retrospect Windows Release Notes say for version 15.5.0 (which is later than you're running, but it may only cost you US$75 to upgrade the Desktop Edition) Second, look in the "Security Settings" section of this KB article, which was updated 15 May 2018 for Windows 10.
  10. Getting back to the latest problems with the Wikipedia articles, DovidBenAvraham has done further work—which Pi314m has left alone so far. It looks as if the fact that other WP editors, who may be administrators, took DBA's side in the latest Request for Comments has at least temporarily persuaded Pi314m to go mess with some other articles instead. Actually it now appears that Pi314m's heart was in the right place when he merged the "Continuous Data Protection" article into the "Backup" article. The difficulty is that there are two types of backup applications that are called "CDP". One is "true CDP", which was invented in 1989 but is only implemented in a handful of applications. "True CDP" applications must get their "fingers" into an OS filesystem at the level where actual disk writes take place; they do so either by requiring that the OS be run inside a virtual machine so that they can get their "fingers" into the VM, or by requiring that special disk driver software with built-in "fingers" be installed. "True CDP" backup can restore interactive applications to precisely the point where the system failed, but they're too expensive in money and complications for ordinary home/SME installations. R. V. (whose spelled-out name I am forbidden to mention on these Forums) may be a "true CDP" backup application, but I can't tell. Much more common and less expensive are "near-CDP" backup applications, which were introduced after the front 7 screen pages of the "Backup" article were written. AFAIK the first of these was Apple's Time Machine, which automatically does an incremental backup once an hour without a script. They are made possible by intent-logging features that are now in all commercial OSs' filesystems, and are made non-burdensome by "snapshotting" facilities that are also in such filesystems (at long last for Apple's APFS, which was introduced at least partly because Apple couldn't bolt "snapshotting" onto its older HFS+). "Near-CDP" backup applications can with proper add-ons restore interactive applications to the last point at which an incremental backup was done, possibly as little as 10 minutes ago, which is close enough for Microsoft Exchange and some database applications. Retrospect non-V. can backup hourly, if you schedule a script accordingly, but it doesn't (so far) do so from "snapshots" (not to be confused with Retrospect Snapshots, which are a different feature named a decade before the industry-wide OS feature appeared—at which point EMC dropped the use of the term Snapshot with Retrospect Mac 8 but not with Retrospect Windows). So DBA had to write three different versions of the above exposition. The first version revises the re-established "Continuous Data Protection" article, with added quotes from the references because Pi314m evidently can't read technical English at a senior-high-school level (possibly as a result of his apparent sub-culture, in which boys past the age of 13 are educated—without any math or science classes—almost entirely in a non-modern European language). The second version is the "Near-CDP" sub-subsection of the "Backup" article, which omits everything but a mention of "real CDP" because ordinary readers will never encounter it. The third version is the "Backing up interactive applications via true Continuous Data Protection" paragraphs of the "Enterprise client-server backup" article, which can omit any mention of "near CDP" because it refers readers to the "Continuous Data Protection" article.

    Catalog Rebuild issues V16 OSX

    bookcent, Make sure you are running the latest version of Retrospect Mac. The Retrospect Mac cumulative Release Notes for version 16.0.1.105 say It's been impossible to turn off "fast catalog rebuild" for a Disk Media Set for several releases; I just tried it. The engineers haven't eliminated the GUI option yet for Tape Media Sets, but it may not work. All my current Media Sets are Disk. If you upgraded to Retrospect Mac 16 in the last 45 days, I suggest you contact Retrospect Tech Support at (888) 376-1078. Otherwise you might consider Removing the Catalog for your Tape Media Set, doing a Finder Delete of the catalog in the folder where it's stored, and creating a new Media Set with the same name and same Members. Before doing that, are you sure your AIT tape drive still works, considering that Sony discontinued AIT tape drives in 2010? Try creating a new Tape Media Set whose sole Member is on a blank AIT tape (assuming you have one—if not you can buy one here), and doing a Backup to it.

    Rebuild issues v 16 Mac OSX

    bookcent, Since your thread title says you are running "v16 Max OS X", you should repost in the "Retrospect 9 or higher for Macintosh" forum. This is the "Windows Products - Retrospect Server, SBS and Multi Server" forum. But anyway, make sure you are running the latest version of Retrospect Mac. The Retrospect Mac cumulative Release Notes for version 16.0.1.105 say It's been impossible to turn off "fast catalog rebuild" for a Disk Media Set for several releases; I just tried it. The engineers haven't eliminated the GUI option yet for Tape Media Sets, but it may not work. All my current Media Sets are Disk.

    can't connect to server

    pbartoli, Have you tried stopping and restarting the Retrospect Engine, as I suggested in the first paragraph in this up-thread post? When you look in Preferences -> General under the Retrospect menu in your console, is the Server Address field filled in—and is it the correct address for your "backup server" machine? If not, I would suggest following the "Installing the Retrospect Console" instructions on pages 12-13 of the Retrospect Mac 15 User's Guide.

    can't connect to server

    pbartoli, This post from nearly 10 years ago is the only one I can find with an answer to your problem. To stop and start the Retrospect Engine, go to System Preferences -> Retrospect on your "backup server" Mac. Make sure you have downloaded version 15.6.1; 15.6.0 was a "bad release", especially for Retrospect Windows. So what changed in your installation's Mac setup just before you started having this problem?

    can't connect to server

    pbartoli, You don't say what version of Retrospect Mac you are running. The last time you made a post that mentioned it, you were running Retrospect Mac 12. Page 19 of the Retrospect Mac 12 User's Guide says Have you recently changed the IP address or System Preferences -> Sharing -> Computer Name of your "backup server" machine?
