I’m deploying MRR storage and planning to enable immutability via the “Enable Retention Lock” workflow at the storage pool level, I’m keen to know anyone’s experience with this because once it’s enabled it’s not reversible.
Typically, when using Retention Lock on a policy copy, we wouldn’t use extended retention on a copy and have the basic retention set to the requirement e.g.:
- One Selective Copy for Monthly backups with the required basic retention
- Another Selective Copy for the yearlies with the required retention
- Both Selective Copies would be pointing to the MRR storage pool with WORM enabled as a dependant copy in the storage pool via the workflow.
Is this the best way to setup MRR with immutability?
