Bacula does not support continuous backups as far as I know. It has to 
scan all the files to find new/changed files to backup. The r1soft agent 
monitors file system writes and backs up changed parts immediately. This 
does allow r1soft backup to restore the system to its latest state 
(10-15minutes ago state, thus continuous backup is achieved) as it 
continually updates the backups. Also has much less stress on the 
systems where the writes are not so much since it doesnt have to check 
every file at each backup cycle. Also r1soft cdp has support for MySQL 
where you can easily restore mysql data in table level if required. It 
is as well supported by a wide variety of web hosting automation systems 
for example H-Sphere ( http://www.parallels.com/hsphere/ ) etc. through 
plugins.

Please see the info about continuous data protection:
http://en.wikipedia.org/wiki/Continuous_Data_Protection

Otherwise I am currently using BackupPC (which is pretty good in my 
opinion and easier to use compared to Bacula) to take nightly backups of 
the servers.

Thanks,
