[H-GEN] Linux Block Level Backups

[Hilton Travis]

G'day Guys and Gals,

I'm looking at a way to get similar functionality to that available with 
Windows-based products such as ShadowProtect that will allow me to run a 
block-level image-based backup with a single base image and 
"incrementals forever", resulting in an easy way to handle offside 
backup replication with significant historical points of recovery.  
ShadowProtect can take snapshots at up to 15 minutely incrementals and 
replicate these offsite (as well as to local storage).

DRBD seems to be able to handle replication (and therefore DR), but 
isn't a backup/archival system - or at least not to my reading thus far.

Does anyone know of any other Linux product that would work in a similar 
way to ShadowProtect with timely "continual" backups?
