Few days ago, Microsoft released a new option for backup policies. Azure Backup now enables you to create a backup policy or modify an existing one to take multiple snapshots a day.
You can create a policy to back up Azure file shares from the Backup policies section of the Recovery Services vault.
Then you can select the following frequencies:
- Daily
- Hourly
