VMware: how big can VM snapshots grow?
Ever wondered how big a VM snapshot (redo file) could grow? It seems that snapshots can only grow to a max of the size of the original VMDK, and never larger. Multiple changes to the same block are only stored once. So the snapshot for a 30GB VMDK could ultimately grow as big as 30GB if every block changes needing a total of 30GB.
