Nimble Snapshot Size

[nimuser]

Hi,

I am looking to find size of each snapshot of a volume and also understand how the size of each snapshot is determined? I was sent info like the following, I am trying to understand what the total size of the each snapshot is and how much of a physical space is being occupied by each.

--------------------+--------------------+----------+------+-------+------------

Volume               Snapshot             Size       Online Status  New Data

Name                 Name                 (MiB)                     (MiB)

--------------------+--------------------+----------+------+-------+------------

A       AdhocSnap              2306867 No     Okay          7317

A      A1-2020-10-15::18:00:21.642    2306867 No     Okay         27372

A       A1-2020-10-14::18:00:22.631    2306867 No     Okay         37534

A       A1-2020-10-13::18:00:29.959    2306867 No     Okay        560692

Have you read the chapter on Snapshots in the Nimble Administration Guide? Available at InfoSight.

After that, look at the Command Reference, starting with the snap command.

Hello Sheldon,

Thank you for your response. I do not have access to InfoSight, I registered there but my email is not linked to my org's Nimble.  Can that be shared with me?

Referring more to your question - Nimble snapshots are redirect on write rather than full copies of your data (ie copy on write). This means that a snapshot is just a metadata file with pointer references to blocks on your array. A Nimble block on your array can be pointed to by many snapshots, but none of those snapshots actually 'own' the data - in esscence not duplicating the data behind the scenes, but also meaning that the size of the snapshot is fluid.
