We have central backup server in our network. There is four WD 120GB
drives in it. With help of ccd I setted up four mirrored sets
55+ GB each and make 4 filesystems. These drives ATA-100 and I use
InnoVision CMD-based controller. (it have internal RAID 0,1 features,
but they not work under FreeBSD)
OS itself installed on separate HDD.
All other servers - 3 FreeBSD and 3 Linux - are backed up to this
central storage using dump utility (via rmt) each night. I configured
them to do cummulative backups with weekly cycle.
Additionally, 3 FreeBSD-based routers backed up with dump to this
central server by hand when something changed in their config.
Next planned step - to install DDS4 drive to backup server in order
to backup The Backup :) using incremental scheme.
Most servers interconnected by 100BASE-TX switches and FreeBSD-based
routers. Transfer rates varies from 5,5 to 10 MBytes/sec. Even in case
of passing FreeBSD-based routers.
Works fine for me.
