Hi list.
I would like to ask which is the simplest yet effective way to dump
backuppc stuff (mainly __TOPDIR__) eg to a removable hard disk that will
be used in a disaster recovery scenario where the plant were destroyed
and I need to restore data from this survivor device. Is a "rsync -aH"
enough?
TIA.

If your 'topdir' is its own filesystem, lvm, etc., you can use 'dump' to back
up a snapshot of your pool. Adapting the link earlier:
#!/bin/bash
EXTDISK=/dev/sdc
POOLDISK=/dev/mapper/Group0-Vol0
lvcreate -l '100%free' -s -n snapshot /dev/volgroup/backuppc
mount $EXTDISK /mnt/tmp
dump -a0f - /dev/volgroup/backuppc | gzip >
/mnt/tmp/pool-backup.0.gz
