Philip, Simple answer is no.
A VM Snapshot should only be used as a temporary roll back option prior to making a system change. After the planned changes are made, and as soon as you confirm there have been no undesired adverse affects, VM snapshots should be removed. Snapshots are certainly not designed to be used as long term backups. This is general virtualisation 'best practice' and not directly related to CloudStack. When a VM has an active VM Snapshot, CloudStack limits certain features such as storage migration so another reason for not maintaining long term VM snapshots.

In principle, VM snapshots look like a very painless way for users to keep backups of VMs (compared with the alternative of doing separate volume snapshots of root disks, data volumes, etc). But when you look more into it (http://kb.vmware.com/selfservice/microsites/search.do?cmd=displayKC&externalId=1015180) you see that a lot of things can go wrong with snapshots. So I wondered if anyone has views or experiences on this, especially where CloudStack is being used as IaaS for paying customers. I am thinking about end users who only have access through the UI or API, not users who have root access to the hypervisors. Are VM snapshots a good strategy for end users to keep regular backups of their VMs??
