@GMENTERPRISES Welcome to Microsoft Q&A Forum, Thank you for posting your query here!
This snapshot size information is not currently available to get per snapshot. if the use-case is to find the largest snapshot to delete, I would suggest deleting snapshot based on age and look at total snapshot size on how much space was freed up.
Azure NetApp Files volumes support up to 255 snapshots per volume. The ability to store many low-impact, frequently created snapshots increases the likelihood that the desired version of data can be successfully recovered.
Snapshots can be vaulted to Azure storage. For compliance and long-term data retention requirements, use the Azure NetApp Files backup functionality to vault snapshots to cost-efficient, ZRS-enabled Azure storage, outside of the volume being protected.
Does snapshot space count towards the usable / provisioned capacity of a volume?
Yes, the consumed snapshot capacity counts towards the provisioned space in the volume. In case the volume runs full, consider taking the following actions:
Resize the volume.
Remove older snapshots to free up space in the hosting volume.
Please let us know if you have any further queries. I’m happy to assist you further.
