Do you know Snapshots - 10/12/2022

We follow a best practices for VMWare snapshots.  See the link below.  

Highlights --

  • Do not use VMware snapshots as backups.

    The snapshot file is only a change log of the original virtual disk, it creates a place holder disk, virtual_machine-00000x-delta.vmdk, to store data changes since the time the snapshot was created. If the base disks are deleted, the snapshot files are not sufficient to restore a virtual machine.
     
  • Maximum of 32 snapshots are supported in a chain. However, for a better performance use only 2 to 3 snapshots.
     
  • Do not use a single snapshot for more than 72 hours.

    The snapshot file continues to grow in size when it is retained for a longer period. This can cause the snapshot storage location to run out of space and impact the system performance.
