Seems wrong to me too considering that I back up about a dozen machines using a plugcomputer with a single ARM core running at 800MHz with just 512MB of RAM and no swap. Heck, I have for kicks got it running on a DNS-323 NAS with I think just 64MB or RAM (though I do have about 512MB in swap) and a 500MHz ARM core. I even run 2-3 dumps at once. The point is that BackupPC typically isn't such a resource a hog by at least an order of magnitude... unless you perhaps have a very different situation from ordinary pc-type backups... ------------------------------------------------------------------------------ Symantec Endpoint Protection 12 positioned as A LEADER in The Forrester Wave(TM): Endpoint Security, Q1 2013 and "remains a good choice" in the endpoint security space.
