Creating a Snapshot of qcow2 Image

 

You can create and maintain one or more snapshots of the qcow2 image to serve as a backup.

To create a snapshot of the qcow2 image:

  • Execute the snapshot_Qcow2.py script from the path where the SDK+AppSupport+Demos+Samples.tar.gz is extracted.

    The script asks for the name of the virtualized SRC instance and the path where you want to store the snapshot.

Note

Before creating the snapshot of the qcow2 image, make sure that the hard disk free space is double the size of the qcow2 image. Otherwise, the script displays an error message.

The virtual machine gets paused while creating snapshots. We recommend you to disable the Juniper Networks database (jdb component) and components involved in service activities during snapshot creation.
