# Purpose {{{
|
|
|
|
|
|
## This script will check if some Ceph related Debian packages are available
|
|
|
|
|
|
## in APT cache.
|
|
|
|
|
|
## And backup all of them (ceph, rados, rbd,…) in tar with version name and date.
|
|
|
|
|
|
#
|
|
|
|
|
|
## You can use this script in a cron (for periodic backup of Ceph packages) or
|
|
|
|
|
|
## directly.
