Is there a plan to support Blob Snapshot?

We need to back up files from a directory on azure VM to a container in azure storage.
- This directory can possibly have couple of TB of data
- Directory can have sub-directories

What we need is:
- Run the sync job periodically (that should sync the files in directory and its sub-directories on azure VM to container in azure storage)
- Snapshot the upload

During Restore
- Download a specific snapshot on Azure VM
- It should pull down all the files tagged with that snapshot

Please note that directory we need to sync has multiple files and sub directories

Not sure if blob snapshot will do the trick or you can suggest some other solution.
