I'm thinking of top, where the total CPU is shown as 100%. But the point holds: I have lots of unused CPU, even with an *anemic* EPIA @ 1.2GHz. I'm still not sure why people say they need multi-GB of RAM and multi-GHz CPU's for their BackupPC servers. I *just* don't see why: I've got a pool >600GB on a *tiny* box (without compression, anyway). Maybe if you've got >1TB of pool data or multi-millions of files you *might* need a little more RAM (and I don't think that is the case), but I *still* don't see why you'd need more than 1GB of RAM, and still no more CPU power. Again, you need a many-drive RAID array *way* more than you do need CPU or RAM. Maybe I'm the only person who's running BackupPC on a box this small. But I've got about a *dozen* of these boxes scattered around various clients, backing up between 10 and 600GB of data. They *all* run flawlessly. Oh, and a *BIG* thank you to Craig for this. BackupPC lets me sleep better at night.
