Bacula is a set of Open Source, computer programs that permit you (or the system administrator) to manage backup, recovery, and verification of computer data across a network of computers of different kinds. Bacula is relatively easy to use and efficient, while offering many advanced storage management features that make it easy to find and recover lost or damaged files. In technical terms, it is an Open Source, network based backup program.
- Bacula's Differential and Incremental normal backups are based on time stamps. Consequently, if you move files into an existing directory or move a whole directory into the backup fileset after a Full backup, those files will probably not be backed up by an Incremental save because they will have old dates. This problem is corrected by using Accurate mode backups or by explicitly updating the date/time stamp on all moved files.
- In older versions of Bacula (
3.0.x), if you have over 4 billion file entries stored in your database, the database FileId is likely to overflow. This limitation does not apply to current Bacula versions. - In non Accurate mode, files deleted after a Full save will be included in a restoration. This is typical for most similar backup programs. To avoid this, use Accurate mode backup.
