RE: [Bacula-users] Scheduling question

In the event of a restore, if I understand it correctly, let me illustrate an example. Say you have scheduled a full backup on Sunday and incremental backups Monday through Saturday. If somebody comes to you on Thursday and says that they deleted a folder on the file server yesterday (Wednesday), the restore would look for the most recent full backup (Sunday), restore it, then restore the changes in the incremental backup Monday, Tuesday, and Wednesday. Now, say I do a manual full backup on Tuesday, to take offsite. In the same restore scenario before, would Bacula then look for the most recent full backup (now Tuesday), and try to restore from it? (Since the tape would be inaccessible.) -----Original Message----- From: bac...@li...

Incidentally, what I meant was that I clicked on the calendar in Data Protector and scheduled each monthly backup by hand (actually, did them monthly but modified those that fell on weekends), meaning that I had monthly backups except certain months and special backups on the first weekday of those special months, etc.. I'm not actually sure how you would handle something like this in bacula, as the schedules are defined prior to launch of the daemons and I'm not aware of any capability to add to the schedule from the console. But you could manually run these backups from the console on the day in question. ---- _ _ _ _ ___ _ _ _ |Y#| | | |\/| | \ |\ | | | Ryan Novosielski - User Support Spec.
