Tools for protecting against data-loss disasters

Data ONTAP provides tools that enable you to back up or replicate data stored at a primary data storage site to an off-site network location. This ensures that you can restore data if data loss is caused by disaster at a primary data storage site.

SnapVault backups for FlexVol volumes

SnapVault is a Snapshot copy backup and restorability tool on FlexVol volumes. You can locate a SnapVault secondary volume on the same cluster or on a different cluster.

Data recoverability
If a data-loss disaster occurs at a source volume, you can restore data that is backed up to a SnapVault secondary volume. You can restore the data to the source volume after it is running again, or you can restore data to an alternate volume.
Currency of restore data
You can restore data from any Snapshot copy that was replicated to the destination system.
Advantage
A SnapVault backup provides an inexpensive backup solution.

Data protection mirror copy

A data protection mirror copy is a Snapshot copy replication, availability, and restorability tool. You can locate a data protection mirror destination on the same cluster or on a different cluster.

Data availability
If a source site experiences a data-loss disaster, you can quickly make available data at the data protection mirror copy destination site.
Data recoverability
If a data-loss disaster occurs at a source storage site, you can restore data from a data protection mirror copy destination volume. You can restore the data to the source volume after it is running again, or you can restore data to an alternate volume.
Currency of restore data
You can restore data from the last Snapshot copy that was replicated to the destination volume.
Advantage
Data protection mirror copies provide data protection and availability.

MetroCluster configurations for FlexVol volumes

MetroCluster configurations provide inter-site, real-time backup, availability, and restorability. You can locate synchronously mirrored MetroCluster systems at different sites, up to 100 km from one another.

Data availability
If a storage site experiences a data-loss disaster, you can quickly make available data that is mirrored to the partner site.
Data recoverability
You can restore data from a mirrored partner site to the source storage system after it is running again, or you can restore data to a system at an alternate location.
Currency of restore data
You can restore data from the time of the last NVRAM checkpoint.
Connection requirements
Data ONTAP cluster connections supplemented with switches and DSL or faster connections are required.
You should preconfigure routers, switches, and DNS servers to direct users to the MetroCluster partner if the clustered system that they first attempt to access is unavailable.
For more information about MetroCluster configurations, see the Clustered Data ONTAP 8.3 MetroCluster Installation and Configuration Guide.
Advantage
MetroCluster configurations provide real-time, off-site protection and availability.
