I just added a new client (Linux, x86_64, RHEL4, 4GB RAM, bacula-fd 1.38.9)
to my existing bacula config. Backups of all other clients are working fine.
The new client has ~4.5TB of local disk, with about 6.5GB used (that'll
change fast!).
The problem is that bacula "estimate" command reports that there's
about 1.14TB of data to be backed up. Attempting to backup this client
seems to confirm that bacula is trying to backup more data than actually
exists--it kept spooling data to the bacula-sd daemon until the job was
canceled (after more than 31GB was spooled).
The bacula fileset and excludes, defined in bacula-dir.conf, are the
same for all my backup clients. That configuration should be backing up
all local filesystems (minus some specified files and directories).
Any ideas why bacula is trying to backup 1.14TB, when only ~6.5GB is
actually used, or how to get more info? Running "estimate" with "debug" set to
200 doesn't produce more details.
I'm also very interested in getting an idea what kind of overhead is involved
(client and server) with the exclude directives that I'm using, particularly
the "wildDir" and "wildFile" statements. Is there any way to optimize the
excludes, by ordering them differently or by ommitting the trailing "*"?
Here are some details:
