Introduced in AOS 5.18 is a feature known as the Recycle Bin, which is enabled by default and allows a 24-hour hold on VM files that were deleted and need to be recovered, unless the cluster free storage space reaches critical thresholds.
This feature was introduced to simplify the recovery procedure for accidentally deleted storage entities (Virtual Machines, Volume Groups, or individual disks). You can disable and enable the recycle bin or clear its contents.
To restore an entity, you MUST contact Nutanix Support.
