Creating a Backup using lkbackup

!Before performing a LifeKeeper or OS upgrade, create a backup of your LifeKeeper hierarchies on all nodes.

To create a backup run the following command:

/opt/LifeKeeper/bin/lkbackup –c

The backup will be created in a file called:

/opt/LifeKeeper/config/archive.<date-time-stamp>.tar.gz

Automatic lkbackup

*An automatic lkbackup runs in versions 7.5 and above.
The backup file is saved with the name:
/opt/LifeKeeper/config/auto-backup.<x>.tgz (where <x> is a sequential number)

To change the time of the automatic lkbackup:

1. Go to /etc/crontab

The entry looks like this:

0 3 * * * root /opt/LifeKeeper/bin/backupadm -c (3 represents the hour the backup will run)

2. Change the hour to the desired time

Restoring a Backup

*Restoring from a backup is limited to current versions only. Backups should not be restored across versions.

To restore a backup run the following commands:

1. /opt/LifeKeeper/bin/lkcli stop

2. /opt/LifeKeeper/bin/lkbackup –x –f <file-name>

3. /opt/LifeKeeper/bin/lkcli start

*Restore the backup on all systems in the cluster.

The use of lkbackup with DataKeeper resources requires a full resync.
