Resilience in Amazon FSx for NetApp ONTAP
The Amazon global infrastructure is built around Amazon Web Services Regions and Availability Zones. Amazon Web Services Regions provide multiple physically separated and isolated Availability Zones, which are connected with low-latency, high-throughput, and highly redundant networking. With Availability Zones, you can design and operate applications and databases that automatically fail over between zones without interruption. Availability Zones are more highly available, fault tolerant, and scalable than traditional single or multiple data center infrastructures.

Infrastructure
In addition to the Amazon global infrastructure, Amazon FSx offers several features to help support your data resiliency and backup needs.
Backup and restore
Amazon FSx creates and saves automated backups of the volumes in your Amazon FSx for NetApp ONTAP file system. Amazon FSx creates automated backups of your volumes during the backup window of your Amazon FSx for NetApp ONTAP file system. Amazon FSx saves the automated backups of your volumes according to the backup retention period that you specify. You can also back up your volumes manually, by creating a user-initiated backup. You restore a volume backup at any time by creating a new volume with the backup specified as the source.
For more information, see Protecting your data with volume backups.
Snapshots
Amazon FSx creates snapshot copies of the Amazon FSx for NetApp ONTAP volumes. Snapshot copies offer protection against accidental deletion or modification of files in your volumes by end users. For more information, see Protecting your data with snapshots.
Availability Zones
Amazon FSx for NetApp ONTAP file systems are are designed to provide continuous availability to data even in the event that a server failure. Each file system is powered by two file servers in at least one Availability Zone, each with its own storage. Amazon FSx automatically replicates your data to protect it from component failure, continuously monitors for hardware failures, and automatically replaces infrastructure components in the event of a failure. File systems automatically fail over and back as needed (typically within 60 seconds), and clients automatically fail over and back with the file system.
Multi-AZ file systems
Amazon FSx for NetApp ONTAP file systems are highly available and durable across Amazon Availability Zones, and are designed to provide continuous availability to data even in the event that an Availability Zone is unavailable.
For more information, see Availability and durability.
Single-AZ file systems
Amazon FSx for NetApp ONTAP file systems are highly available and durable within a single Amazon Availability Zone, and are designed to provide continuous availability within that Availability Zone in the event of an individual file server or disk failure.
