I use a similar approach, but backed up to encrypted volumes on removable drives (CRU Dataport 25) that I carry off site. The LVM snapshot is key, so you get an image of the file system in a consistent state (I always create the snapshot when backuppc is idle). A refinement is to alternate among two or more backup drives, so that in case the primary host goes down during a copy, you don't end up with your only backup in an inconsistent state. ------------------------------------------------------------------------------ Protect Your Site and Customers from Malware Attacks Learn about various malware tactics and how to avoid them.
