Create a custom snapshot policy for FSx for ONTAP volumes in BlueXP workload factory. A snapshot policy defines how the system creates snapshots for a volume.
You can create a custom snapshot policy that differs from the three built-in snapshot policies for FSx for ONTAP:
-
default -
default-1weekly -
none
By default, every volume is associated with the file system's default snapshot policy. We recommend using this policy for most workloads.
Customizing a policy lets you specify when to create snapshots, how many copies to retain, and how to name them.
-
Consider the following about snapshot capacity before you use snapshots:
-
For most datasets, an additional capacity of 20% is enough to keep snapshots for up to four weeks. As data gets older, its use for restorations becomes less likely.
-
Overwriting all the data in a snapshot consumes significant volume capacity, which factors into provisioning volume capacity.

To create a custom snapshot policy, you must associate a link. If you don't have an existing link, create a link. To associate a link in the file system, select Associate link under Account name. Once the link associates, return to this operation.
