If you are referring to a VMware snapshot of a virtual disk it is bit a backup of the disk but log file recording changed to the underlying virtual disk -

When you merge a snapshot those changes are merged on to the underlying virtual disk - if discard the snapshot the virtual disk will revert to the exact state the disk was in when the snapshot was taken -

Hi Friend,

I assume you are talking about VMware snapshot:

Here are some one point stop resources to understand the snapshot & merging :

VMware KB: Understanding virtual machine snapshots in VMware ESXi and ESX

Best practices for using VMware snapshot:

Nice details on what is snapshot and what snapshot is not

Hi Satish,

just keep one thing mind whenever u are working with VMware...don't consider VM snapshot as a backup ..its just like a restore point..

use other backup solution to taking care of vm backup. To merge snapshot is best practice do it one bye one  like newer to older..

Thanks

Restore snapshot, or we say commit the DELTA files to the original VMDK. This process is actually create a second snapshot. All writes that the VM performs now, go into the second snapshot and let the first snapshot commit to the original VMDK.
