Hi Philippe
It looks like the first block header of your volume somehow got corrupted.
Could you try to read the first 24 bytes of that volume and send them
here ?
The block header is supposed to look like this:
https://docs.bareos.org/DeveloperGuide/mediaformat.html#block-header
While its probably not possible repair the block header ourselves, we
might be able to identify which byte was not written
and try to put it into a state where bareos will accept it.
Kind Regards
Sebastian Sura

Hi Andreas,
thanks for clarifying this. So, probably at least after Bareos
throwing the "does not exists" error the file shows up with a size of
61GiB.
Taking a closer look this report seem to have two errors, one
"non-fatal" error saying
Volume data error at 0:256! Wanted ID: "BB02", got "B02". Buffer
discarded.
and the "fatal" error related to the non-existing file at some point
of time.
I don't know what's broken here but since the errors are refering to
different files every day regarding the fatal error but not the
"non-fatal" error, I believe the AI-Incremental-0525 file (which
exists for a month now and is 530M of size) might be corrupted.

So, are some of my backups lost? What can I do here - remove the
nextcloud-jobs and all previous backups and start from scratch?
Kind regards,
Philippe
