What is machine snapshot?
A virtual machine snapshot (VM snapshot) is the state of a virtual machine (VM) that is copied and stored at a specified time. It develops a copy of the VM that is used for VM migration, backup and restore procedures. A virtual machine snapshot allows a VM to be restored to a former state of snapshot creation.
Can we take snapshot of powered off VM?
Snapshots limitations VMs with independent disks must be powered off before you take a snapshot. Snapshots of powered-on or suspended VMs with independent disks are not supported. Snapshots are not supported with PCI vSphere Direct Path I/O devices.
How many snapshots we can take?
Maximum of 32 snapshots are supported in a chain. However, for a better performance use only 2 to 3 snapshots. Do not use a single snapshot for more than 72 hours. The snapshot file continues to grow in size when it is retained for a longer period.

How are snapshots created in a virtual machine?
Each time you revert a snapshot and take another snapshot, a branch (child snapshot) is created. The first virtual machine snapshot that you create is the base parent snapshot. The parent snapshot is the most recently saved version of the current state of the virtual machine.
How to take a snapshot of an image?
Locate the snapshot (.vmsn) or suspend file (.vmss) in the virtual machine directory; the vmss2core tool also accepts monolithic or non-monolithic memory (.vmem) files Run the vmss2core tool with the -M flag to create a core file (vmss.core) with a physical memory view suitable for the Gnu debugger gdb
What happens when you remove a snapshot from a VM?
Removing the snapshot does not destroy any data in the virtual machine. You keep all changes made since you took the snapshot, then permanently accumulate additional changes as you run the virtual machine. You cannot revert to a previous state because the snapshot no longer exists.
When to use a snapshot in a test?
Snapshots are useful as a short term solution for testing software with unknown or potentially harmful effects. For example, you can use a snapshot as a restoration point during a linear or iterative process, such as installing update packages, or during a branching process, such as installing different versions of a program.
