Amazon FSx for Windows File Server provides fully managed, highly reliable, and scalable file storage that is accessible over the industry-standard Server Message Block (SMB) protocol. It is built on Windows Server, delivering a wide range of administrative features such as user quotas, end-user file restore, and Microsoft Active Directory (AD) integration. It offers single-AZ and multi-AZ deployment options, fully managed backups, and encryption of data at rest and in transit.
Amazon FSx for windows file system backups are block-based, incremental backups, whether they are generated using the automatic daily backup or the user-initiated backup feature. This means that when you take a backup, Amazon FSx compares the data on your file system to your previous backup at the block level.
Amazon FSx can take an automatic daily backup of your file system. These automatic daily backups occur during the daily backup window that was established when you created the file system.
By default, FSx backup is enabled and the retention period is set to 7 days.
