You don't say how big the drives are, but 40 hours says "terabytes" to me. If that's not the case, I'd seriously consider [re]examining your rsync version on the client. (Or perhaps beefing up your server.) It's also possible that the client is underpowered in terms of CPU or RAM for the vast numbers of files involved; it may be worth examining the client during a backup to see what kind of resources it's using. (I generally don't see a lot of slowness, even on active machines, here, but we're not backing up terabytes from workstations, either.) The suggestion you already made (namely, breaking the three modules into three hosts) is probably the next thing I'd try. ------------------------------------------------------------------------------ Live Security Virtual Conference Exclusive live event will cover all the ways today's security and threat landscape has changed and how IT managers can respond.
