Why tape, buy a ATA (IDE) RAID controller that allowes hot swap and hot
plugable devices (e.g. 3ware). Then setup a raid1 between two harddiscs.
Whenever you like to do the backup simply mount that array, rsync /home
to it and umount again. The next morning, exchange one of the discs agains
a new one, the discs are your backup medium. The new disc will be rebuild
automatically and be available for the next backup after a few hours.
Sounds strange? Well never got the change to test it myself but it could
- Cheaper: RAID Controller (300€) + Drive Bay (200€) + 4 drives (100€ pro
60GB) are about 900€. This is more than competable with DAT/DDS3 and even
more with DLT tape drives.
- Faster and easier when restoring. Obviously, just mount it.
- More capacity per medium. Splitting up across several media makes things
