Size of the future / change rates of volume snapshots

ITExpert — Mon, 08 Jan 2024 09:27:47 GMT

Hello everyone,

I would like to determine the change rates of the snapshots for our volumes. The only way I currently see is to record all snapshots in a table and repeat this process multiple times for data comparison. But that can't be the only solution.

Does anyone have an idea?
Could it possibly be done with a script + perhaps NetApp API?

Are you currently using this command ?

::> volume snapshot show-delta

::> volume snapshot show-delta -vserver <vserver> -volume <volume> -snapshot1 daily.example -snapshot2 hourly.example

volume snapshot show-delta (netapp.com)

hello:

Snap delta is used to display the data change rate between two snapshot copies. If no parameters are used, it shows the data change rate between snapshots of all volumes in the system. If a volume is specified, it will display the data change rate of that specific volume. snap reclaimable volname snapshot-name

Best regards.
