Grml's persistence feature is the same as Debian LiveCDs - just create
an ext3 partition labeled "live-rw" and boot with the kernel option
("cheat code") of "persistence", and everything's automatically
persistent. Can also use a loopback file if you don't want to dedicate
a partition (although this could just be a USB). Can have a separate
partition/USB/file for /home as well or instead, or take manual
fs-snapshots if you prefer.
It's also easy to setup GRUB2 to boot a Debian-based ISO from the HD
if you're booting it regularly, much faster, more durable and more
convenient than physical discs.
Tangential thinking out loud:
If you have a limited time window to back up a lot of clients, this
allows you to have multiple BPC hosts running concurrently without
having to dedicate hardware to the task - a well-segmented network
scheme and fast clustered SAN/NAS storage will help reduce the
bottlenecking from those factors. Or at the other extreme, have a BPC
boot disc/image on key hosts configured to automate backing up to its
own dedicated filesystem (external drive for off-site rotation) -
multi-platform "Time Machine" functionality.
