On my NAS where I have a datastore for my vms I noticed that there is a folder named .snapshot and within that I can see several other folders named hourly.0, hourly.1,hourly.5, nightly.0, nightly.1, etc.
Within these folders i can see the .vmdk files for the vms running on the host. It seems to be taking up quite a lot of space on my NAS now as it's filling up now.
I only have about 3 vms out of 25 running snapshots and I currently run VDP to backup my vms.
Any idea what this folder is for and if I can remove or to clear up some space on my NAS?
Thanks in advance
