Answer

  • System Configuration Backup file is everything needed to bring the cluster and nodes back to the operational state (in case of disaster) when the configuration backup was taken.
  • Node backups include configuration files under /mroot/etc/ and in cfcard  including bootargs.
  • Cluster backup files contain the node configuration and RDB replicated records backup for each node in the cluster.  
  • Additionally, they contain manifest and md5 signature files.
  • Internal Structure of Backup Files:

cluster_backup_file
|-> MANIFEST
|-> node1name/node1_backup_file
|-> node2name/node2_backup_file
|-> cluster_replicated_records/replicated_records.7z

Additional Information

  • RDB is a replicated data base of the cluster configuration.  It contains names of ports, LIFs, SVMs, and volumes and other configuration information. No client data is kept in RDB.
