What are the differences between AWS File Gateway and Volume Gateway?

AWS Storage Gateway is a hybrid cloud storage that enables low latency access to on-premises clients and applications using industry standard storage protocols like NFS, SMB and iSCSI. AWS Storage Gateway offers three types of Gateways – File Gateway, Volume Gateway and Tape Gateway. In this post, I will provide the differences between File Gateway and Volume Gateway.

AWS File Gateway AWS Volume Gateway
AWS File Gateway provides access to Amazon S3 Storage using file level protocols NFS and SMB.AWS Volume Gateway provides access to Amazon S3 storage using block level protocol iSCSI, in two modes, cached and stored.
In addition to NFS and SMB, you can access your files as objects through S3 bucket directly using S3 API.You cannot access your files through S3 API directly. You can access only through iSCSI using Volume Gateway or through EBS volume using EBS snapshots.
You need only cache disk for local storage, minimum VM disk is 1.You need both upload buffer and cache disk for local storage, minimum VM disks are 2.
You can take backups by enabling S3 versioning on the S3 bucket. You can use S3 lifecycle policies to maintain versions.You can take backups using EBS snapshots which are stored in S3. You can use AWS Backup to schedule and maintain backups.
Maximum file shares for a file gateway are 10.Maximum volumes for a volume gateway are 32.
Using S3, you can have virtually unlimited storage for the file share size.Maximum volume size for cached volume gateway is 32 TiB, stored volume gateway is 16 TiB.
