Hello,

I had similar problems with virtual and accurate backups until I made sure
that the indexes on my mysql database were the bacula defaults.
In particular, I had these indexes on my File table:

JobId
JobId, PathId, FilenameId
PathId
FilenameId

Once I had removed the PathId and FilenameId indexes, my queries changed from
taking many hours to taking about a second.

To check these on your database:
Log into mysql.
use bacula;
show indexes from File;

If you have any extra indexes, you can drop them like this:

drop index <index name> on File;
e.g: drop index PathId on File;

If you need to add one:

create index <index name> on File (<list of fields>);
e.g: create index JobId on File (JobId);
