[linux-lvm] LVM Snapshots for remote archiving.

Hi! I've been looking through the archives and I can't see anything
addressing my issue. Probably because I didn't look hard enough.
I want to use 24-hour snap shots as an archival tool.
I have 2 identical file servers, one primary and one as an off-site
mirror. I'd like the primary system to generate a transaction log that
rolls over every 24-hours and gets transmitted to the remote site.
After 7 days on the remote site, the log gets triggered so the remote is
always 7 days out of sync but with the last 6 days logs ready to go. I
could have it auto update on arrival, but I was thinking that allowing a
week for someone to realize that they deleted something vital would be a
good thing(TM) - standard archiving stuff I guess.
Do you think that lvm snapshot volumes are a simple and convenient way
of doing this? Does this make sense at all?
