Does Azure File Share support immutability features?
Asked by

I'm looking to enable immutability (WORM or Write Once Read Many) for Azure File Share, but I've noticed that only Blob Storage mentions support for this feature in the documentation. Has anyone successfully implemented immutability or any similar data protection mechanisms for Azure File Shares? I'm particularly interested in options like legal hold, snapshots, or backups, and would appreciate any insights or workarounds that have worked well in production.

There’s also a managed solution from Veeam called Data Cloud Vault, which is a more cost-effective option at per TB billing compared to setting up your own solution.

We’ve set up immutability for our Azure Files using the Recovery Services Vault, applying a Files Vaulted Standard policy. Just a heads up though, there are some limitations, like a maximum size of 10TB per share, and it might lead to higher costs.

Currently, Azure Blob Storage is the only native service with immutability support. However, there are partner solutions, like Komprise, that provide SMB shares backed by Blob Storage which utilize that feature. You might also want to check out Azure NetApp, as they might have options related to this too.

DataWiz42: NetApp indeed has support for WORM storage options and has been doing so for a long time.
CuriousCat123: Thanks for the info! I'll look into that.
