I backup well over 3 TB of data from over 30 sources, workstations and servers. Fortunately, we have gigabit switches now. Most computers come with gigabit network ports by default. We use an external drive enclosure which we switch out weekly off-site connected on an eSATA port. We also two network ports in the backupPC server, and they are teamed. So, our server has a 2-Gb connection. Three backups at a time is a good choice. If you try more, they start to slow each other down. I also recommend using eSATA over USB or Firewire. Backups are going all the time, and nobody seems to notice that some bandwidth is being used for backups. I have also noticed, for whatever reason, that machines with gigabit ports do only a little better than the ones with 100Mbps ports. I did notice that a few users still had little 10Gbps switches in their offices. These switches were a major slowdown. I replaced them.

Hi, I've been doing backups with BackupPC for quite a few years, mainly backing up 2 or 3 servers. I've recently installed BackupPC at the office and am 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. How many servers and how much data do you backup using BackupPC? Gerald
