    Multiserver client/server compatibility between 7.7 and 8

    It makes sense that Server 8 would require Client 8, but I'm wondering if Server 7.7 with Client 8 is supported.
  2. We have the business requirement to have a Windows 2012 box added to our Retrospect backup architecture. Windows 2012 is only compatible if Retrospect Client 8 is used. However we are still using Retrospect Server 7.7. Is this setup, having clients in versions 7.7 and 8 being administrated by a Server 7.7 machine, compatible or allowable? We don't want to be forced to upgrade the server version, and all the client versions, if Server 8 is not compatible with Client 7.7, if not absolutely necessary. I cannot find any documentation to support or condone this type of setup.

    Missing backup reports after 7.7.620 upgrade

    I've worked around this issue. I've got one machine per retrospect server that's set to backup after the bulk of all backups. These trailing machines aren't monitored (development machines and the like), so they act as a log pusher for the important/monitored backups. They backup last, pushing the logs to file, making the other machines report OK, while not caring if their own logs are pushed out. This is not the best solution going forward, given this process will break if any backups finish after them, but it's the best I can do without reverting retrospect versions (really don't want to). Hopefully this bug will be addressed soon.

    Missing backup reports after 7.7.620 upgrade

    I still have logging on. It's just annoying, because it appears to be a "push text buffer to file" option that's been removed. When a new item is logged to file, the buffer's pushed to file (the previous action is logged to file), then the new report is generated, but not pushed. It's also continually happening, I have 100% completed backups again today, but one per server are showing as not completed in my monitoring.

    Missing backup reports after 7.7.620 upgrade

    I upgraded to 7.7.630 on my fleet of retrospect backup servers (all Windows Server 2008 R2 DC, Dell R510's) a few days ago, and since then I've noted missing backup report log items. This is important because, given there's no other way in retrospect to do this, I parse the backup log to confirm that my clients have been backed up successfully. For the past two days, I've been missing 1 backup report log item per Retrospect server. The client in question has been backed up, I can confirm that by looking at the operations log. However, the backup report log (Backup Report.log) doesn't show the latest entry for the client being backed up. Has anyone else noticed this bug, and is there a way around it? edit: I believe it may be related to the buffering of output. I did some work on one of the servers, which generated some output to file, which also dumped the last backup to file, and my check returned ok. I'm currently performing another backup on another server, to see if the currently-pending backup is dumped to file. edit2: yes, definitely confirmed. I back up clients A, B and C, and A and B dump to file, client C, finishing last, is not dumped to file. After all backups completed, backing up client D causes client C to dump to file, but client D's logs are still 404. The Operations log is definitely right though. Attempting to force the dump by running a known quick action, e.g. a verify of a backup, doesn't fix the dumping, though.

    Dealing With -1101 Groom Failures

    Thanks for all your answers. I'll see if I can't put a few like-machines together to get retrospect to show me it's superpowers.

    Dealing With -1101 Groom Failures

    Backup sets = ~70 (same number as clients) 8 execution threads, backups run from midnight to ~5am. The repair-catalog process did work, no grooms failed over the weekend; but I fear it will be a few weeks before they fail again. Is it usual in your experience to have to repair broken catalogs on a monthly basis? Also, do you know of any Performance Tuning documentation for Retrospect?

    Dealing With -1101 Groom Failures

    Grooming is weekly, Saturday morning, after the midnight -> 6am backups. Both OS drives have over 200GB of free space, so the catalogs have a fair bit of space to grow. There is a great number of backups being done though, might that cause an issue? Not sure of the exact data volumes, but these machines are backing up about ~70 servers, ~60 on one, ~10 on the other. Would it be prudent to load balance these backups, so that each server handles ~35 each? edit: to give a picture of how much these servers are processing, the backups from Monday morning (over the weekend) generated 523GB of new backups on one server, and 105GB on the other (going by the Completed: XX files, YY GB on the "Normal backup using <script>" part of the backup report.log file), grooming out about ~3TB of data between both machines. Also, I have rebuilt all the broken files (5) on one server; will see in the morning if any of the grooms fail.

    Dealing With -1101 Groom Failures

    Hardware RAID10 SATA drives, the newer machine has seperate RAID10 SAS for the OS drive; both machines are experiencing these issues, the older one more commonly (more backups on it, older, etc). First errors shown on machines around 2-3 months after they went into production.

    Dealing With -1101 Groom Failures

    I have recreated the catalogs multiple times, and the error still returns on the next groom. The errors I'm getting are along the lines of: Bad Backup Set header found (0xa600b000 at 875,243,022) Bad Backup Set header found (0x1b14fee0 at 875,265,796) Backup Set format inconsistency (7 at 1032409029) Bad Backup Set header found (0x5f6ef45b at 875,288,570) Bad Backup Set header found (0x40404040 at 875,290,194) Bad Backup Set header found (0x33577a4e at 875,291,814) Bad Backup Set header found (0xffffffff at 875,293,510)

    Dealing With -1101 Groom Failures

    I'm encountering a number of backup set grooming failures, in the form of: Grooming Backup Set blerg... Groomed zero KB from Backup Set blerg. Grooming Backup Set blerg failed, error -1101 ( file/directory not found) You must recreate the Backup Set's Catalog File. See the Retrospect User's Guide or online help for details on recreating Catalog Files. Can't compress Catalog File for Backup Set blerg, error -1 ( unknown) In the past, to correct these issues, I've done the following: * create a backup set called blerg_copy * change the nightly script to use blerg_copy, not blerg * after a period of retention, remove blerg. However, these issues keep appearing. I believe they may be hardware related (issues with incomplete backups, forced hardware restarts), but I'm unsure how best to address these grooming failures. Is my above approach accurate? I have attempted a backup set transfer, but on a 500GB backup set, I encounter in excess of 11,000 errors in 6 hours of processing, so I cancelled the execution.

    Grooming Removes Snapshot Listings, But Not Files

    Ok, I'm part way through my next groom (issues with windows updates meant this hasn't been running, because the retrospect launcher isn't working to restart retrospect on reboot, sad panda), and I'm getting a heap of -1101 errors: "Grooming Backup Set [xyz] failed, error -1101 ( file/directory not found)". I'm guessing this is related to the files I removed that weren't being updated, etc. Removing .rdb files from explorer is bad, mmkay? I'm hoping a re-catelog might fix it, but I"m thinking I might need to do a full backup of all the failed sets to get them back in a usable state, amiright?

    Grooming Removes Snapshot Listings, But Not Files

    I've upped the log retention to ensure I can see things from the weekend. (Should see stuff from 48 hours before still) As far as I know, we started with Retrospect 7.7 in January, with no previous versions.

    Grooming Removes Snapshot Listings, But Not Files

    I just ran a one off groom, and I got a similar log file. It groomed 41.2GB out of a 214.5GB backup set, so that's ok. Checking the file makeup, it's got a full set of .rdb 618MB files from day-0, and most files since then are partials, so that looks ok. I can't check the main log from the main groom, because retrospect lost that log (more than 100 events ago, or something), but it's weird that the groom doesn't seem to be taking much effect when it's run as per usual. Might have to go along the 'more space' route, after checking how much we're actually backing up. Over 5 days, we have 1.1TB more disk space in use, which doesn't make sense though :/

    Grooming Removes Snapshot Listings, But Not Files

    We have a weekly grooming script, but all backup sets are set to 99% capacity (the default). Would it be an idea to set a limit of (retention) x (max storage size) per backup set to reduce filesize? I know the sum of all the maximum backup sets will exceed our current storage, but then at least the files should reuse themselves, yes? I think I tried this on a test backup, but it was asking me for new media from the overnight run. :/ The logs usually say 'grooming was successful', but comparing the before and after drive usage for the collection of backup sets, barely any data has been removed, if any. I'm going to have to also check how much we are trying to backup vs disk usage, current storage capacity of backed up devices, and compare that to the storage we have on the backup server. As a side note, do you know an easy way to export any of the information collected from the retrospect clients? e.g. the data in the volumes, clients, backup set listings? I can manually collected this data, but it would be far simpler if I could export it from Retrospect. Thanks for all your help so far
