Synthetic full backups or consolidation. A feature that is in the development queue and could (in my opinion) be one of the major new things in a 3.1 release, i.e. perhaps next year. To learn more, search the bacula-devel list archive for subjects containing "Synthetic" or "Consolidation" - you'll find that, if someone invests money or programmer's time, this project could be started. > Ofcourse Bacula can do this if you simply never cycle the original Full > Backup and retain *all* incremental backups since the beginning, but > this is not what I mean. This is, also, usually not what you want unless you use "accurate" backups, available in the current development version (because a normal incremental backup doesn't know about moved or renamed files).
