RE: recommendation for mirroring software

Sounds like a job for a RAID array - two identical disk where one mirrors the
other (raid 1 - http://en.wikipedia.org/wiki/RAID). Windows XP Pro supports
that:

(from Help) dynamic disk
A physical disk that can be accessed only by Windows 2000 and Windows XP.
Dynamic disks provide features that basic disks do not, such as support for
volumes that span multiple disks. Dynamic disks use a hidden database to
track information about dynamic volumes on the disk and other dynamic disks
in the computer. You convert basic disks to dynamic by using the Disk
Management snap-in or the DiskPart command line utility. When you convert a
basic disk to dynamic, all existing basic volumes become dynamic volumes.

Now there are many backup programs that do real-time backups, but that won't
give you a disk that's can take over right away in case of a disk crash.
