I have just begun using rsync at Caroline Chisholm Catholic College,
Braybrook, Australia. To complete backups of our home directories to an off
site server. The link between the servers is 32MBps (soon to be 100MBps when
Australian Comms Authority licence for the microwave spectrum goes through)
and both servers are 1GHz Celerons with 512MB RAM.
They both run on a 120GB RAID 0+1 configuration (120GB available to use,
240GB total in disks). They are running Linux, with kernel version 2.4.15.
100MBps network cards in each.
I have run rsync to copy 100GB across the link (multiple sized files, mp3s
(unfortunetly students like their illegal music), word files, databases,
etc) I have not had a single problem with it. Rsync seems to use all the
bandwidth it can get, but since the syncronisation is completed overnight
(2am) there is no worry about it distrupting network operations.
Great work guys.
