Amazon S3 File Gateway now supports DOS attributes



[Amazon S3 File Gateway](/storagegateway/file/) now supports capturing, retaining, and enforcing DOS attributes listed in file metadata. Previously, files copied to the gateway were copied without this common metadata (Archive, Hidden, Read Only, and System). Support for DOS attributes is intended for users who want to hide files or folders, enforce read only access at the file or folder level, or mark files as archived once moved to Amazon S3. Amazon S3 File Gateway users who archive data often need the data and its corresponding metadata to remain intact for consistency and compliance purposes. Other gateway users want to denote that files moved to Amazon S3 are now “archived”, when viewing the files on the gateway. In both cases, the gateway will now capture, retain, and enforce the metadata flags for A = Archive, H = Hidden, R = Read Only, and S = System. Customers can preserve attributes that their file system will enforce, even if the data moves to Amazon S3, is removed from the gateway, and then recalled back to the gateway from Amazon S3\. Customers maintain complete control over these metadata flags even as they persist into Amazon S3. Amazon S3 File Gateway enables your on-premises applications to seamlessly store files as objects in Amazon S3, and access them using industry standard file access protocols such as NFS and SMB. You can use Amazon S3 File Gateway for migrating on-premises file data to AWS while maintaining fast on-premises access to recently accessed data, backing up on-premises file data to AWS, and providing on-premises applications low latency access to data stored in Amazon S3. This capability is now available on new gateways in [all commercial regions](/about-aws/global-infrastructure/regional-product-services/). For existing gateways, this new capability will be made available during the next scheduled software update.
