How would you suggest I troubleshoot this issue. I have successfully set up xsibackup DC on 3 hosts and backups are going well. On a single VM, xsibackup fails to create a snapshot and thus does not back up the vmdk files as they are excluded/in-use. The verbose output does not report an error and if i manually create a snapshot prior to backup, the backup runs because a previous snapshot exists.
output below is truncated

There isn't any sign that the snapshot is failing to be taken. Can you see something denoting that in the ESXi log?
Nonetheless the -flat.vmdk file does indeed seem to be blocked.
Check whether there is some .lck file on the flat file from some previous interrupted process and delete it manually should it exist.
Offline
So far I have not found anything to explain it - still looking. There are no .lck files and vmkfstools -D doesnt show a lock on the vmdk file. Either way I can create and remove snapshots manually on the VM. I do not see any errors in logs.
Offline
Is that file in a cluster?, is it being open by some other process?
What kind of DS is it residing in?
Something is clearly holding it at the time to backup.
What type of guest OS are you running?.
Offline
yeah it is odd - i figure i will go through shutting it down - unregistering and re-registering when i get a moment.
it is in a cluster but all other vms are as well. on VMFS6 and Win 10. I just wish i could see an actual error
Offline
well whatever it was has been cleared up by unregister/re-register. thx.

There's been errors related to snapshots in Windows since ever. Now in more recent versions of ESXi and Windows the problems not only didn't cease, but they seem to have managed to create a bunch of new ones.

[url=https://kb.vmware.com/s/article/60395]Windows Server 2019 snapshot error[/url]
Whatever is holding the file, it is outside the guest.
What type of Datastore are you using?
It might not be a cluster lock that you are experiencing.
Offline
i see. the odd thing is that i was able to make a snapshot via vcenter when xsibackup failed to. it is on iSCSI vmfs6. it seems to be working now once it re-registered.
Offline
That doesn't mean anything, the snapshot could be failing due to some heavy load during the backup per instance, or some missing software in the guest, like VMWare Tools, or even some faulty service that causes the snapshot request to time out.
You should check the guest's logs more than the ESXi host itself when you have this kind of issue.
