Hola
en el manual de bacula indica:
*compression=GZIP* All files saved will be software compressed using the GNU
ZIP compression format. The compression is done on a file by file basis by
the File daemon. If there is a problem reading the tape in a single record
of a file, it will at most affect that file and none of the other files on
the tape. Normally this option is *not* needed if you have a modern tape
drive as the drive will do its own compression. In fact, if you specify
software compression at the same time you have hardware compression turned
on, your files may actually take more space on the volume.

Software compression is very important if you are writing your Volumes to a
file, and it can also be helpful if you have a fast computer but a slow
network, otherwise it is generally better to rely your tape drive's hardware
compression. As noted above, it is not generally a good idea to do both
software and hardware compression.

Specifying *GZIP* uses the default compression level 6 (i.e. * GZIP* is
identical to *GZIP6*). If you want a different compression level (1 through
9), you can specify it by appending the level number with no intervening
spaces to *GZIP*. Thus *compression=GZIP1* would give minimum compression
but the fastest algorithm, and * compression=GZIP9* would give the highest
level of compression, but requires more computation. According to the GZIP
documentation, compression levels greater than six generally give very
little extra compression and are rather CPU intensive.

You can overwrite this option per Storage resource with
AllowCompressionAllowCompression option.
suerte!!
hace mucho usé bacula y tuve muy buenos resultados...
