Hyper-V Backups - Checkpoints
  • RI IT Support
    1
    Running 6.3.4.38 . Cloudberry now is requiring checkpoints to be enabled in order to complete hyper-v backups. Ok fine, I enabled checkpoints. Now I have full tree's of unmerged checkpoints for all my virtual machines.

    If cloudberry is going to require checkpoints for hyper-v backups, it should be able to merge (delete) the checkbpoint after the backup operation is completed.

    A tree of checkpoints can reduce VM performance from a disk I/O perspective. Cloudberry needs to actually test the results of the updates they make for huge application changes such as this!

    Merging the checkpoints should happen automatically. I had someone in Support test on Hyper-V and he was not able to reproduce this issue - all the checkpoints (both Production and Standard) were being merged right after the backup completed.

    To see why you're running into this issue, we'll need to have you create a Support Ticket. You can open one up from the Tools | Diagnostic toolbar option or on the web site.

    Thanks.

    We too are running into this issue at multiple sites. Cloudberry support said its a known issue but that thought makes me cringe that this could crash our servers. My colleague can comment more on this issue and maybe provide a fix.

    I am now having this issue with 2 of our client machines as well. I will be opening a support ticket on it .

    We are seeing this across 18 sites currently, I've opened a ticket with no result thus far.

    Currently we have rebooted one host and it is currently merging the data for us where as we couldn't merge manually before... This is still a WIP and I'm not sure what the outcome will be.

    Update: restarting the vmms service will start a merge.

    I can confirm that this works. I did restart VMMS on several servers. Surprised about this easy fix. Thanks Connor :smile: :up:

    I did also try AZSBTools Merge-VMDisks - which works - but shuts down the VM. Restarting VMMS results in a merge whilst the VM is online (which is preferable).

    The only problem is the issue continues to happen after the merge, so I ran backups on one of the machines after merging and the next day had the same issue again.

    Same issue here.
    I reported this in a ticket and it was immediately escalated.
    The Powershell command Merge-VHD worked great, however you will need to remove and re-add the drives on restart.

    This is the best way to do this, perhaps there's a post backup plan script that can be run to restart the service and automatically complete these merges.

    Issue still persists across multiple versions, strange I don't find other hyper-v backup providers customers reporting this issue.

    The test build 7.2.2 doesn't seem to have the issue (I've seen it on one server but it seems it may of been a fluke).
