+#### Azure File Sync support for system-assigned managed identities is now generally available
+
+Azure File Sync support for managed identities is now generally available, enabling customers to be secure by default.

 #### Azure Files vaulted backup is now generally available
 
 Azure Backup now supports vaulted backup of HDD file shares to protect against ransomware and data loss. You can define backup schedules and retention settings to store data in the Backup vault for up to 10 years. Vaulted backups provide an offsite copy of your data. In case of data loss on the source account, you can restore it to an alternate account. You can manage vaulted backups at scale via Azure Business Continuity Center and monitor them using Azure Backup's alerting and reporting features.
