 Customers using NFS Azure file shares can now take point-in-time snapshots of file shares. This enables users to roll back their entire filesystem to a previous point in time, or restore specific files that were accidentally deleted or corrupted. Customers using this feature can perform share-level Snapshot management operations via REST API, PowerShell, and Azure CLI. This feature is now available in all Azure public cloud regions.

+#### Expanded character support for Azure File Sync
+

This expansion allows users to create and sync SMB file shares with file and directory names on par with NTFS file system, for valid Unicode characters. For more information on unsupported characters, refer to the documentation [here](/troubleshoot/azure/azure-storage/file-sync-troubleshoot-sync-errors?toc=%2Fazure%2Fstorage%2Ffile-sync%2Ftoc.json&tabs=portal1%2Cazure-portal#handling-unsupported-characters).
