My network is rather smaller but still bigger than most home systems. Please keep that in mind.
The backup server is a very elderly "Intel(R) Core(TM)2 CPU
6600 @ 2.40GHz" with 8G RAM. /var/lib/backuppc is a ZFS raidz array of
three 4TB disks, giving a useful space of 3.6T, of which 1.1T is now
used. The CGI interface reports:
There are 9 hosts that have been backed up, for a total of:
* 109 full backups of total size 15511.81GB (prior to pooling and
compression),
* 65 incr backups of total size 235.11GB (prior to pooling and
compression).
but I like to keep an archive as well as a backup so storing 15.5TB of
files in 1.1TB of space may be misleading because there are so many
files de-duplicated.
The server is on a single 1 gigabit NIC. It runs up to four backups
simultaneously and a full backup of a 0.4TB machine takes araound 12
hours; this appears to be disk IO bound at each end as incremental
backups of other machines proceed at a decent rate.
TL:DR: A 10 year old box very easily copes with my load. YMMV. In
particular, you may wish to have more than one ethernet NIC and perhaps
more RAM.
