In general, if you choose option 5 on the restore prompt, Bacula will indeed want the Full and all the intervening Incremental and Differential backups.
However, it may not be well known, but one *can* restore just the files from any given Incremental or Differential backup without the Full backup. You simply need to know the JobId of the Incremental or Differential backup, and with a different option on the restore prompt, you can enter the JobId and restore from it. Also, Bat has a restore that will work with all backups automatically and allow you to choose any file in any backup. Doing restores from specific JobIds is perhaps a bit unusual but just the same possible. Best regards, Kern > > I would suggest using not incremental but differential backups.
