If things were implemented the way you describe below, then it would seem that base jobs would be possible as a specific case, with no code changes needed. > Ie. after > archiving any file, you store the file size and the crypto checksum in > a DB, right?

I think this would be a lovely feature to have, but it's not the way bacula works at the moment, and it would probably require quite some code changes, and changes to the way restore behaves. I guess care needs to be taken here - restores are not something you want to break :) > I've been using AMANDA for a while, particularly because it can easily > support bare-metal-recovery and it's free.

The multiple volumes per backup bit is quite a 'selling point' for bacula in the open source backup world at the moment I think. -- Russell Howe [EMAIL PROTECTED] ------------------------------------------------------- This SF.net email is sponsored by: Splunk Inc.
