Or I can add this kind of feature on FreeBSD > system ? 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.
