Do you know that a file system level backup is only useful if
a) the postgres instance is stopped or b) your are using WAL archiving and have an appropiate setup to tell PG about backup starts and ends
c) your are using lvm (or zfs) snapshots and know that postgres would run recovery after backup restore.
