My Jellyfin VM has been failing its nightly backups for some time now (maybe a week or so).
I’m currently backing up to a NAS that has plenty of available space and my other 10 VMs are backing up without issues (though they are a bit smaller than this one).
I am backing up with the ZSTD compression option and the Snapshot mode.
The error is as follows:

Anyone experienced this or have any suggestions as to resolving it?
Update: After rebooting the Proxmox node (not just the VM) my backups are now working again. Thanks all for the input!
Woa, hit the breaks on the rebuild.
I’m old and my memory is going, but I know I’ve had this before …
I think I had to figure out how to -
I know this seems like it should be block level and that shouldn’t matter, and I could be remembering wrong - but I really think I went down that path and it ended up being the solution.
Luckily rebooting the host solved it :) the regularly scheduled 3 AM backups went off this morning without issue.
