Backups for Blob storage as NFS?

Hello all,
The questing is as follows. I have a Blob storage account that I want to mount as NFS 3.0. I see there is no option for blob(file) backups like there is when mounting with blobfuse(when it's not hierarchical namespaces). So what are my options when it comes to backups? Do I make another machine and store files as backups with scripts or is there any other built in function like versioning, soft delete that works on NFS 3.0 that I don't know about?

Thank you.
