Hi Chris,
The storage will be iSCSI (over gigabit), and offsite backups will be done via an archive done once a week. Does that sound sane?

also two network ports in the backupPC server, and they are teamed. So, our
server has a 2-Gb connection.

been doing backups with BackupPC for quite a few years, mainly backing up 2 or
3 servers.

backing up 6 servers right now, with room to grow. The current backup
(Veritas BackupExec) keeps around a year of data, which is close to 2.5
TB. Since I plan on phasing out Veritas for BackupPC, I'm looking at
similar sizes for my data. All my backups will be via ssh/rsync and
Samba/Windows shares.
