Regarding with slide Prepare for an Upgrade, p. 277 on LECTURE_MANUAL-SLE321v15-SUSE_Linux_Enterprise_HA-v15.LMS.pdf, it occurs some questions:

  1. What does it mean Backup and Test the backup can be restored?
  2. Is there any script to make backup? Is there any script to restore the cluster based on backup?
  3. Or is the process completely manual?
  4. What are the best practices to backup a cluster?

Best regards,
Luís Sousa
