LVM2 snapshots allow you to backup live filesystems. Usually, you
shouldn't backup a live (i.e. mounted and being used) filesystem with

backed up to avoid changes made by running processes.
A LVM2 snapshot, however, guarantees consistency as it "takes an
image" of the filesystem and freezes it which can be backed up to
tape, or to remote storage without worrying about possible
inconsistencies caused by running processed modifying data.
That seems very good, where can I find more information about this? Or
what should I google for exactly?
Maybe you can get started by reading this:
