one thing you need to remember though is that ...
disk mirroring will not protect you from software errors
... you do "rm -rf" from "/" by mistake or have software corruption that affects the box and your box is toast because that error is also propagated to the mirror disk ...
you might want to do snaphot copies of your mirrors to a non-mirrored disk through a nightly cron job using unix backup utilities (i.e., dd, ufsdump, tar, cpio, etc.) just so you can at least recover quickly to a known clean point without resorting to fresh rebuilds and restores from backup tapes ...

UKOPP(1) Ukopp man page UKOPP(1)
NAME
Ukopp - copy files to USB stick or other disk or disk-like device
SYNOPSIS
ukopp [ -nogui ] [ -job | -run ] jobfile
DESCRIPTION
Ukopp is a graphical menu-driven program operating in its own
window. Ukopp copies the files and directories specified in the
job file to disk or disk-like media (e.g. USB stick).
OVERVIEW
Ukopp works incrementally: only files that are not already identical
on the target media are copied (new and modified files or files newly
added to the backup job). Files/directories to include or exclude can
be selected from the file system hierarchy, using a GUI navigator.
Specifications are saved in a job file which can be re-edited and/or
executed. Ukopp can be run in batch mode using the -nogui option.
Ukopp can optionally keep old file versions instead of replacing them
with updated versions. The retention time and/or the number of old
versions to keep can be specified for each selected file or directory.
File owners and permissions are retained even if the copy media has a
Microsoft file system.
Summary of functionality:
- Copy files incrementally with optional file version retention.
- Three media verification modes: full, incremental, compare.
- Report disk:backup differences in detail or summary form.
- Select and restore files from backup media or use drag and drop.
OPTIONS
Command line options:
[ -job ] jobfile open job file for editing
[ -nogui ] -run jobfile execute a job file
SEE ALSO
The online user manual is available using the menu Help > contents.
This manual explains Ukopp operation in great detail.
