Hmm, but it doesn't save your ass on harddisk failures. :-| Wintel decided that they don't process
relevant data at all since the user
in most cases has noc chance to backup his data to something useful (no
1,44MB Disk please). Backing up a Windows so that it can be reinstalled
on a possibly different hard disk or machine is another story. Almost
impossible. No Problem on Linux or *BSD...
I've heard very good things about CrashPlan. They let you run on local disks or LAN
machines for free, but they also have a pretty attractive offsite solution. Never used
them, but Neil Gaiman does. :-)
On OS X, TIme Machine is fantastic. It's actually brilliantly simple; it just makes
hard links to the files for each iteration (except the modified ones, which it copies) so
that you have a working image for each backup that is indistinguishable from a
non-incremental backup (and the hard links only take up the space of an inode each).
It's so simple that I'm surprised I'd never seen it anywhere else.
