Very reliable and useful software.
I heard of it reading the eBook "Take Control of Easy Backups in Leopard", which I recommand :
See what Joe Kissell says :
"That said, you can have your cake and eat it too (for a price). If
you use SoftRAID (http://www.softraid.com/, $129), you can create
a RAID in which your internal disk is mirrored onto two or more
external drives at once. You can then periodically rotate one of the
drives off-site, where it will function as a stand-alone duplicate of
your disk at an earlier state. When you plug it back into your Mac, it
will automatically synchronize with the remaining drives in the RAID.
The beauty of this approach is that you never have to set up, schedule,
or run backup software to make duplicates-it happens automatically.
This scheme can even be expanded to include archives. Using
SoftRAID, it is possible (though a bit awkward) to partition an
external drive so that one partition is used along with your internal
drive to form a mirrored RAID while another, non-RAID partition
on the external holds archives. Set up two drives this way and you're
in business-as close to a painless backup system as I can imagine."
So, I use it :
- to prevent a disk failure,
- in my backup strategy, in order to have a mirror of all my important disks in both my home and my office. Each of these disks is connected to a mirror disk in each place : either I rotate the mirror or I move the main disk.
Add an overnight daily incremental backup, and you get a rock solid backup strategy.
Most of all, Mark James has always been incredibly reactive and helpful : for example, I had an issue today (jan. 1st !!) with a corrupted syslog file, I got an answer from him within a few minutes.
