The first thing to do is see what physical size your Volume is as compared to what the catalog thinks it is.  If the volume is very small, some one has truncated it, otherwise, probably the beginning of the Volume was damaged either by some program or by a bad disk block.

You might try examining the Volume with bls, and in particular with the -p option which should make bls ignore a number of possible error conditions.  If bls can read the volume, then you may be able to read it by running bacula-sd with the -p option, or by using bextract ...

If the beginning of the volume has been damaged, it could also be possible to manually copy a few bytes (probably about 20) from some valid Volume so that Bacula or one of the utilities can recognize it as a Bacula volume.  The whole volume label is typically between 100-200 bytes, but only the very first few bytes are needed so that Bacula can recognize it.

Best regards,
Kern

Hi all

 

I need help. I have to restore files from my backup.

My bacula makes backup to volume type file.

 

I get this error :

 

JobId 3928: Error: block_util.c:308 Volume data error at 0:0! Wanted ID: "BB02", got "". Buffer discarded.

JobId 3928: Warning: acquire.c:276 Read acquire: Requested Volume "Full-0590" on file device "File-***" (/Backup/**/Bacula/) is not a Bacula labeled Volume, because: ERR=block_util.c:308 Volume data error at 0:0! Wanted ID: "BB02", got "". Buffer discarded.

 

 

Can you help me ?

Thanks
