I take it DAR backs up to another hard disk in the system. Correct me if im wrong. That would be good for fast backups an quick restore but hard to take the backsup off site in case of fire. I do a complete backup of the samba share across the network to a windows machine on a hard drive in the system just for that purpose an its quick fast at about 2 hours to backup the 11 gigs an compare them. I need the tape backup for removing the night before's backup off site, aka taking it home with me. Then if the building burns down You have your data off away from the fire an in a safe place. I just copied the 11 gigs off to my test bench machine an fixing to see how long it takes to backup that 11 gigs of stuff with bru now.
DAR will backup your files into 'slices' that can be any size of your choosing. There is also a program called daromizer that will run those slices off onto CD's, DVD's. You could also run the slices off to tape. I was using daromizer for awhile but ran into too many errors on my RW DVD's so I now use DAR to back up to disk, and then a separate process to offload onto DVD's. That way, if I get an error, I haven't lost the slice like I would if using daromizer. I can retry to off-load. Dar will compress files to a level of your choosing (speed -size tradeoff) and also avoid compressing files that shouldn't be (you choose). Things like .bin, .jpg, etc. It's a nice program. I can backup 13G's of stuff in about 2.5 hours.
