Today our backups are made on DDS-4 tapes, they are very slow and too
small, this is our problem. What is a good (modern) alternative to
DDS-4 working on FreeBSD?

For our multi-TB systems, we do disk-based backups using dar ... to
another multi-TB system. :)

We use a custom shell script to handle creating full and incremental
backups and to rotate through multiple directories to keep a couple
backups around. All via gigabit ethernet and NFS. And once a week we
copy a full backup offsite via SSH tunnels to another multi-TB system via
a gigabit fibre link.

We're using RAID5 with hot-spares on 3Ware 9550SX controllers.

Hi,

Any issues withe RAID5 sets on the 3Ware controllers? I've heard bad things
about RAID5 on older 3Ware controllers when a disk fails. Just wondering
if the situation is improved.

Thanks,

Gary
