Hi All,

We have a setup with  bacula-dir/MySQL and bacula-sd (2 servers) and a
SAN connected via fiber. We are running bacula with about 250 jobs a
day. The table File is about 500M records with a size of about 100G. We
use batch insert. All tables are MyISAM. Currently we are experiencing
performance problems with the database.

For all jobs we do a disk-to-disk backup. The next day we use a copyjob
to put the data on tape. During daytime we run the copy jobs and during
the evening/night we run the disk-to-disk jobs. There is some overlap.
When the the disk-to-disk jobs start, we see number of queries on the
database drop to virtually 0.

There are a few options to solve this

- use innodb for the tables in MySQL
- migrate to PostgreSQL

Can anyone advise me what to do, to increase the performance of our
platform?

Kind regards,

Enrico van Goor
