"What makes CrashPlan so compelling to me is that my mom can use
it to backup her Windows box to my Linux PC, from across the state
-- automatically simply by having the PC on and scheduled to do the
backup. It is very simply to use and honestly, it has never failed
"I also like that CrashPlan offers both incremental and
differential backups, so I am not filling up space that is really
unneeded. At the end of the day, this is as secure as Amanda but as
simple to use as sbackup. And it has offsite network storage with
self-discovery of other CrashPlan awareness on your LAN. This means
other PCs or Macs with CrashPlan installed can be set to "see" one
another to make networked backups a simple thing.
"The biggest two downsides unfortunately, include the sbackup
USB hard drive problem meaning PCs used to backup to ought to be
left on. And of course, it is not open source."
