SQLite is generally recommended only for small installations with no
other DB. PostgreSQL or MySQL is much preferred. Of the two, many
reports indicate that Bacula does not perform well with PostgreSQL on
backups, because PostgreSQL is much slower than MySQL on writes. There
are tuning factors that can influence this.
Also, have you tried using spooling? It is designed for situations in
which your tape device is much faster than your clients can supply data.
I did not try spooling for two reasons. First is that the backup server
only has about 70 GB diskspace (two SATA disks in a mirror
configuration). Many of the servers have more data to backup than this,
and the total backup set is several times this. I got the impression
that spooling only works if the backup server has enough diskspace to
hold all the data from a single client.
Second, the disks can in the best case only deliver about half the raw
write speed of the tapestreamer. This is if the disks are not doing
anything but reading. But in the spooling case the disks would still be
spooling data from other clients, so I think I would get maybe 1/4 of
the tapestreamers potential with this method.
Thanks,
