Error chunk

[frankz]

Hello everyone, I noticed several warnings of this type:

2024-05-18T17:35:10+02:00: WARN: warning: unable to access non-existent chunk 293bc44c

Hi,
this indicates that your datastore most likely is corrupt and at least one of the chunks got missing. Did you perform any actions on the datastore before the problem arouse?

You should set up a verify job for this datastore and let it run immediately [0], so that snapshots which are referencing this chunk are flagged as corrupt and the chunk might be re-uploaded on a following backup run, if the data on the client side did not change since then. If that is the case and the chunk can be re-uploaded, you are lucky and all snapshots will be fine again, otherwise all the snapshots referencing this data chunk are not usable anymore.

Please verify to flag such corrupt snapshots and if the data has not changed, re-upload the missing chunk. This will help ensure the integrity of the backups.
