Ho-lee crap, this is fantastic.  Everything seems to work.  I find thou=
gh that if I stop myth -and- mysql, I cannot export the database, so I =
only stop Myth.  It's the only thing using the database anyway, in my c=
ase.

Well it's been 12 hours and I'm still doing my first HTPC data transfer=
, so not all commands are tested (untested=3D=3D#), but I am confident =
they will work.  I'm donating my (weekly) cron script here in case it h=
elps someone. (below)

I have four systems:
hex - work laptop
droog - HTPC with a 4TB btrfs raid0 array on /home and 500GB raptor on =
/
slepnir - backup server in a cube case out in the garage (in case of th=
eft or fire) with a SuperMicro 5 disk hot-swap cage, 6TB so far. (WD Gr=
een 2TB now $80 with rebate!)
phone - Android Nexus One with 16GB SD

The backup server has SSH credentials on the other systems, but only th=
e work laptop can ssh to it (limited by Shorewall).  The backup server =
will also handle security cameras and will presumably dnat a port to th=
e HTPC, which will serve it to the WAN on SSH (reverse tunnel) so I can=
 get motion notifications and video on my phone. (ZoneMinder)  The HTPC=
 is the only system allowed to present anything to the WAN as it has no=
thing sensitive, and -that- will be on a subnet.  Maybe I can limit it =
to my phone's IP.

I do have a (disused) WindowsXP partition, but unsure how to back that =
up.  Maybe ssh with a dd command.

Thanks for the help all.
