  5. To view the snapshots, go to left-side navigation pane and click Instance Snapshots. You can see the progress and status of the snapshot.

Time required for each snapshot creation may vary because of the

  • disk volume.
  • Creation of the first snapshot will take relatively longer than subsequent snapshots due to the first snapshot being a full snapshot.
  • However, depending on the amount of changed data since previous snapshots, the length of time for each snapshot creation varies.
