Best practices for using snapshots in vsphere environment

Snapshots are good way of creating a quick recovery point in case the changes to be performed in immediate future cause VM to crash. However, there are best practices for using snapshots such as:

• We should not use snapshots as backups. There should be separate backup mechanism for backup.
• We should not use more than 2 or 3 snapshots in a chain.
• It is not ideal to keep snapshot for more than 2-3 days. As soon as activity is over and VM is stable, snapshots should be deleted
• If snapshots are used for backup process, then after backup is complete the snapshot should be deleted
• We should delete snapshots before increasing VM disk space by increasing size of virtual RDM.
