Indeendent and dependent disk modes

[baber]

As I read a few documents about independent and dependent disk I understand following is that correct:

I read this document

Virtual Machine Disk Modes

independent-persistent disk = this type is such as dependent disk just we can not get snapshot from disk in this mode

independent-non persistent disk = in this type after reboot-poweroff/on all of data on that disk will be remove

Is that correct ?

Yes, it sounds like you understood the modes correctly.

”Independent” means independent of any VM snapshots, so the virtual disk will be excluded from any snapshot taken of the VM. This is true regardless of “persistent” or “non-persistent”.

"Persistent” means data is written to the virtual disk immediately and there is no reversal of changes during VM operations such as a power off/on.

"Non-persistent” means that changes to the virtual disk are written to a delta file rather than to the base file, so the virtual disk reverts to the previous state when you power off/on the VM.
