I have an Overland Arcvault 12 library with a full LTO3 magazine of 400/800 GB tapes. It is connected directly to the fileserver via a SCSI card/cable.

The two main directories I want to back up are /var/log, which is on one filesystem, and /home, which is on another.

There are _currently_ no databases to worry about, but there may be active users logged in and active jobs running. We'll just take our chances with what can be backed up.

I've successfully run dump/restore to an external USB 1 TB hard drive as our backup device until the tape library arrived. Now, finding the appropriate dump and restore commands to throw into a script is the fun part. The first time will obviously produce a full backup of said directories to back up. Subsequent ones will be incremental.

What should my dump lines look like for both full and subsequent incrementals? And, to test the backup and in case I need to retrieve a file, what should a respective restore line look like?

Thanks much.

Scott
