Here is a datapoint. I am backing up 2000+ user directories on 1600 mac workstations with a 'cluster' of 7 low end 1U servers via xtar (needed to pick up resource forks). Each server is connected to a Exastore NAS from which they mount the /var/lib/backuppc and /etc/backuppc directories. Each server is limited to 6 backups at a time and they average a load of 2 - 5. The cluster currently uses 4TB on the NAS which is roughly 6TB of data from the workstations. I have written a few glue scripts so that new workstations are added automatically to the 'cluster' and the load is distributed among machines in the 'cluster'. I say 'cluster' because it is not a true fail-over cluster in that each server node is responsible for its set of workstations and the cpool is not shared among all server nodes. For all intents there is no limit to how much this architecture can scale -- I just add on more server nodes as needed. cheers, ski -- "When we try to pick out anything by itself, we find it connected to the entire universe" John Muir Chris "Ski" Kacoroski, kacoro...@gmail.com, 206-501-9803 or ski98033 on most IM services ------------------------------------------------------------------------------ Apps built with the Adobe(R) Flex(R) framework and Flex Builder(TM) are powering Web 2.0 with engaging, cross-platform capabilities.
