I currently have a maintenance plan which does a consistency check and
then database backup followed by log backup (the latter is needed if you
don't want your log files to grow to infinite size when a database is in
'Full' recovery mode).
This currently runs asynchronously w.r.t. bacula, so I just make sure
that I schedule the bacula job to run at a time by which the database
server will have dumped its backups.
I also have a client run before job script (shell script executed with
cygwin), which prunes backup dump files older than a week, and gzips the
remainder (SQL Server backup files gzip rather well, I find). I think I
trust gzip to do a better job than the tape drive's hardware compression.
If you look at the maintenance plan, all it does is call a stored
procedure with some arguments. It should be trivial to call this from
the client run before job too, making the whole process synchronous.
I also saw someone having some success running backups over named pipes
and streaming them directly to tape, avoiding the middle step of dumping
databases to files before backing up. I like having an online copy of
the database backups though, as it makes restoring in the common case
("something went wrong and we need last night's backup now!") much
easier. Backups are handy for recreating test copies of databases too.
I've posted the prune & compress script here before, so it should be in
the archives somewhere. It's nothing fancy.
