This is, unfortunately, a known issue (which obviously becomes more serious as Bacula is used in bigger and bigger installations). If I understand it correctly, Kern has some ideas how to handle this problem but will probably not work on it really soon. There are several possible solutions: - Avoid Bacula building the whole directory tree by using other selection methods. This will not work if you need only a set of files and don't know which ones before you start the restore job. - You can try to modify your MySQL configuration so that it uses less memory, but I don't think this will help you - the problem is inside Bacula itself. - Fix Bacula yourself :-) - Or try the recover.pl script from Karl Hakimian, which is in the examples directory in the cvs tree. It works with PostgreSQL only AFAIK. It might be possible to adapt it to MySQL, I think. - Finally, you can try a script recently mentioned: http://brestore.webhop.info/ is definitely worth a look, but it requires a graphical environment and GTK.
