[linux-lvm] LVM Snapshots for remote archiving.

[Chris Beck <cbeck@gene.concordia.ca>]

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?

Thanks,
Chris
