Understand data protection and disaster recovery options in Azure NetApp Files

  • บทความ

Learn about the different data protection and disaster recovery features in Azure NetApp Files to understand what solutions best serve your needs.

Snapshots

The foundation of data protection solutions including volume restores and clones and cross-region replication, Azure NetApp Files snapshot technology delivers stability, scalability, and swift recoverability without impacting performance.

Benefits

  • Efficient and frequent primary data protection for fast recovery from data corruption or loss
  • Revert a complete volume to a point-in-time snapshot in seconds
  • Restore a snapshot to new volume (clone) in seconds to test or develop with current data
  • Application-consistent snapshots with AzAcSnap integration and third party backup tools

To learn more, see How Azure NetApp Files Snapshots work and Ways to restore data from snapshots. To create a Snapshot policy, see Manage Snapshot policies in Azure NetApp Files.

Backups

Azure NetApp Files supports a fully managed backup solution for long-term recovery, archive, and compliance. Backups can be restored to new volumes in the same region as the backup. Backups created by Azure NetApp Files are stored in Azure storage, independent of volume snapshots that are available for near-term recovery or cloning.

Benefits

  • Increased productivity, reliably integrated service that is easy to manage and can be set once
  • Application-consistent backups with AzAcSnap integration
  • Retain daily, weekly, monthly backups for extended periods of time on cost-efficient cloud storage without media management

To learn more, see How snapshots can be vaulted for long-term retention and cost savings. To get started with backups, see Configure policy-based backups for Azure NetApp Files.

Cross-region replication

Using snapshot technology, you can replicate your Azure NetApp Files across designated Azure regions to protect your data from unforeseeable regional failures. Cross-region replication minimizes data transfer costs, replicating only changed blocks across regions while also enabling a lower restore point objective.

Benefits

  • Provides disaster recovery across regions
  • Data availability and redundancy for remote data processing and user access
  • Efficient storage-based data replication without load on compute infrastructure

To learn more, see How volumes and snapshots are replicated cross-region for DR. To get started with cross-region replication, see Create cross-region replication for Azure NetApp Files.

Cross-zone replication

Cross-zone replication leverages availability zones and the same replication engine as cross-region replication. This technology creating a fast and cost-effective solution for you to asynchronously replicate volumes from availability zone to another without the need for host-based data replication.

Benefits

  • Data availability and redundancy across zones within regions
  • Bring data into same zone as compute for lowest latency-envelope
  • Efficient storage-based data replication without load on compute infrastructure
  • Lower TCO due to absence of data transfer fees

To learn more, see Understand cross-zone replication. To get started with cross-zone replication, see Create cross-zone replication relationships for Azure NetApp Files.
