Snapshots in VMware vSphere often cause various problems with configurations and performance, unless they are properly used – for live backup of virtual machines and temporary keeping VM configuration before the update.
However, using them in large infrastructures is unavoidable. At some point you may need to delete/consolidate virtual machine snapshots (Delete All button in Snapshot Manager), which is quite time-consuming and demanding in terms of storage performance. Thus it would be a good thing to know in advance how much time it takes.
