Snapshot: how is uniquename used?

Postby QM » 16. Apr 2018, 16:08

How is the uniquename parameter used in snapshot?

The help shows:
Code: Select all   Expand viewCollapse view
snapshot take <name> [--description <desc>] [--live] [--uniquename Number,Timestamp,Space,Force]

but no explanation is given for these. In fact, a search for 'virtualbox snapshot uniquename timestamp' only turns up regurgitations of this syntax help. Have I missed something?

The name is what is shown beside the snapshot in the manager UI. The name you are asked for if you use tha UI to create the snapshot.

Not that it should matter much, since experienced people don't use the snapshot feature anyway. Google for why.

You have not managed to explain the use of these options, only some result. Examples?

I don't think I've ever heard of anyone using this feature. It's an exotic thing that was most probably due to a customer requirement and never got the full attention it needed. You can find where and how it's used to uniquely identify the description of a snapshot in the following file:
https://www.virtualbox.org/browser/vbox/trunk/src/VBox/Frontends/VBoxManage/VBoxManageSnapshot.cpp

Search for "SnapshotUniqueFlags".
If you obfuscate any information requested, I will obfuscate my response. These are virtual UUIDs, not real ones.
