I wouldn't try backing up a live partition due to issues with
referential integrity. Suppose two interdependent files, A and B, change
during the backing up, like so:

A is backed up.
A and B are both changed.
B is backed up.

Your originals are fine, they both have the changes. But the backup is
broken: only one file has the changes.

The only exception to that is an LVM logical disk (or similar) where you
have taken a snapshot, and you back up the snapshot.
