[Bacula-users] Volume File trashed

[Steven J. <ad...@ct...>]

I recently started using bacula, and have been working out kinks in my setup.
Because of this, I do not have very many full backups to work with. In fact, I
have only one. I am attempting to restore a folder that was deleted accidently
(gotta love working the help desk). It is not a particularly large folder--308
files in sub-dirs, about 15MB, however it was part of a fairly large backup. I
back up to a hard drive. The Volume file this job is in is 17GB. When I run the
restore job, no files are restored, but bacula doesn't seem to crash. I have
restored files from other Volumes, and they work fine, but none from this Volume.

When I use bls/bscan the file errors out twice. Once with a checksum error,
which can be bypassed with the -p option. The other time is with a bad block
size--something like 15000000 bytes. This promptly results in a segfault. I
can't use bextract because the data is Win32.

Using bls to list filenames, the files I want are listed before the errors.

Any ideas on how I can restore this folder? I'm fairly desparate. 

Here is the output from bls -c /etc/bacula/bacula-sd.conf -V Vol0001
/var/big/backups -v -k -d 5 -p 

...
bls: bls Error: block.c:313 Volume data error! Block checksum mismatch in block
118422: calc=4179ab03 blk=f81ce5a6
