Step 2: Back Up the Cluster from the Controller CLI

Cluster backup creates a backup of the entire cluster.

1. Log on to the controller CLI as a system administrator.
2. Run the enable command to enable privileged mode on the CLI.

   ruckus> enable
   Password: ********
   ruckus#

3. Run the show diskinfo command to determine the current disk size of the node.

   To complete the cluster backup successfully, the /mnt directory must have at least 50GB (53,687,091,200 in 1K-blocks) of free disk space.

   ruckus# show diskinfo
   Filesystem           1K-blocks      Used Available Use% Mounted on
   rootfs                 4128448    315520   3603216   9% /
   /dev/root              4128448    315520   3603216   9% /
   /dev/sda1              2064208     97208   1862144   5% /boot
   /dev/mapper/vg00-lv00
   41276736   5646756  33533240  15% /mnt
   tmpfs                  1048576       696   1047880   1% /tmp
   tmpfs                  3066864         0   3066864   0% /dev/shm

4. Run the backup command to start the backing up the current cluster.

   ruckus# backup
   Do you want to backup system in this context (yes/no)? yes
   Backup process starts.
   Backup process has been scheduled to run. You can check backup version using 'show backup'.

5. Run the show backup command to verify that the cluster backup file has been created successfully.
