Dell PowerFlex 4.5.x Administration Guide

Restoring

Restoring PowerFlex Manager returns user-created data to an earlier configuration that is saved in a backup file. To restore from a backup, you need to run a script outside of PowerFlex Manager. The user interface does not support the ability to restore from a backup.

1. Login to the node where the PowerFlex Manager platform (PFMP) installer was initially run.
2. Run the restore script that is included with the installer bundle:

   ./restore_backup.sh

3. Provide details as needed to complete the execution of the script.
   You will be prompted to provide the SSH username and password. In addition, you will be asked to specify whether the passwords are the same for all nodes, and also provide the location of the backup file and the encrypted password for the file. You may also be asked to provide the CIFS username and password. The CIFS credentials may not be required for a CIFS share that allows for anonymous access.

   NOTE:The passwords must be in base64 encoded format.

   To complete the execution of the restore script, you must specify whether the restore operation will be performed on an existing cluster or a new cluster.

   Here is a snippet that shows a sample run of the restore script:

   [root@sheetal-installer scripts]# ./restore_backup.sh
