John, IMO, the point behind BackupPC is to use cheap, easily upgradeable disk media to make backups available and easy. That kind of steers me in the direction of several low-end backup servers, either with separate storage or all sharing a big fat fiber channel NAS. Buying a high end machine and trying to handle what is essentially a very parallelizable task on a single box is sort of self-defeating, I think. So, my response would be to keep what you've got and buy another machine to offload some clients.
There is definitely some tuning involved with respect to server performance, given the various file systems, operating systems, physical hardware choices. But BackupPC can be tuned considerably based on the transfer protocols and number of simultaneous backups. Have you exhausted these options? I'm sure you'll get a different answer from every person on the list, since most of what you're asking is kid-in-the-candy-store questions. If you're maxing out a single server, chances are, you'll be better off with two (or more) servers, or the one you have isn't configured for maximum efficiency. And get a good 3ware RAID card. :-) Hope that helps, JH John Pettitt wrote: > > > It's time to build a new server.
