Support use of snapshots in katello-backup to allow service to be restored quickly
Description of problem:
katello-backup is horrendously slow, and while the backup is being taken
the satellite system is offline (since the services have been shutdown).
My customer is reporting that their backups are now taking over 11hrs
In order to minimize the time taken for the we should support
taking LVM snapshots of the various volumes for postgresql, pulp,
mongodb (and any other required data).
The technique is as follows. Use SSM to manage the snapshots.
- Shutdown services
- Create snapshots and mount them
- Restart services
- Backup snapshots (without
v and -z, see bz#1283578) Unmount and remove snapshots
Version-Release number of selected component (if applicable):
Without using this procedure, backup speed remains unacceptable
Restoration of the satellite services is much faster.
There is no need to wait for the backup to complete.
