To protect your snapshots against accidental deletion, Azure Backup has added one more level of security to the Azure file shares snapshot management solution by integrating with the Azure Files platform capability of acquiring a lease on the snapshots. The lease operation creates and manages a lock on the snapshots for delete operations. After taking a snapshot, Azure Backup takes an infinite lease on it. This lease protects the snapshot from accidental deletion. To ensure that a snapshot does not get deleted during a restore operation, Azure Backup also checks the lease status at the beginning of the restore, and in case it is found to be non-leased, it acquires a lease on the snapshot.
