Snapshot Prerequisites

Important:

Maestro Security Groups that contain different Security Appliance models do not support Gaia Snapshot operations (in the Global Gaia Portal or Global Gaia Clish).

To collect or import a Gaia Snapshot in such a Security Group, connect directly to Gaia Portal or Gaia Clish on each Security Appliance in the Security Group.

  • We recommended to configure the GRUB password. See System Passwords.

  • Before you revert to a snapshot on a new appliance, or after a reset to factory defaults, you must run the Gaia First Time Configuration Wizard and configure the same settings as before you created the snapshot.

  • Before you create a new snapshot image, make sure the appliance or storage destination meets these prerequisites:

    • The required free disk space is the size of the system root partition multiplied by 1.15.

      Note - A snapshot image is created in unallocated space on the disk.

      Not all of the unallocated space on a disk can be used for snapshots.

      To find out if you have enough free space for snapshots:

      Step

      Instructions

      1

      Connect to the command line on the Gaia computer.

      2

      Log in to Gaia Clish.

      3

      On Scalable Platforms, go to Gaia gClish:

      Type gclish and press Enter.

      4

      Run:

      show snapshots

      The output shows the amount of space on the disk available for snapshots.

      The value in the output does not represent all of the unallocated space on the disk.

    • The free disk space required in the export file location is the size of the snapshot image multiplied by 2.

      The minimum size of a snapshot image is 2.5GB.

      Therefore, the minimum necessary free disk space in the export file location is 5GB.
