Does anyone see what could be the reason

Thanks greetings

hi,

does the NAS work normally without problems, i.e. can you see files, delete/replace copy etc. without any problems?

is this the only VM with this problem, or also others?

does backup work normally when you select local storage?

Hi @oguz
Thanks for replay.

NAS work normally, besides I have another one from Qnap and its have similar error:

Problem occurs only on one VM, backup on other works good.

On local storage backup this VM have similar error.

Thanks.

Anyone had a similar case?

NAS work normally, besides I have another one from Qnap and its have similar error:

On local storage backup this VM have similar error.

then probably the issue is not related to the storage but to that specific VM.

i also see that the problematic VM has a much larger disk compared to the other one. do you have enough space to save this backup? maybe it's just running out of space.

otherwise it's also possible the VM disk is corrupted/damaged. you can check by running fsck or a similar tool in the VM to see if there are any filesystem errors
