Like everyone else, I have been reviewing the Release Notes for the latest Update 1 release of vSphere 4.1, but I decided to point out specific fixes that will make full image VM backups better for everyone. Note that I work for Veeam Software, but the fixes I am referring to are all VMware resolved issues that surface from time to no matter what backup solution you use. There are numerous other fixes and impovements in the U1 release, but, since most of my world is backup these days, these particular items â€œpopped outâ€ at me.
Your vSphere VMs may be running from snapshots even though you didnâ€™t create them. That is, if a scheduled job which auto creates snapshots runs into a datastore with insufficient free space. In this scenario a special Consolidate Helper snapshot will be created.
