Data protection

Storage systems provide a wide range of data protection features such as aggr copy, MetroCluster, NDMP, NVFAIL, SnapLock, SnapMirror, SnapRestore, Snapshot, SnapVault, SyncMirro, Tape backup and restore, Virus scan support, and vol copy.

Feature Description
aggr copy This is fast block copy of data stored in aggregates; it enables you to copy blocks of stored system data from one aggregate to another.

For information about aggregates and aggr copy, see the Data ONTAP Storage Management Guide.

MetroCluster MetroCluster enhances SyncMirror functionality for disaster recovery by providing continuous volume mirroring over 500-meter to 30-kilometer distances.

For information about disaster protection using MetroCluster, see the Data ONTAP Active/Active Configuration Guide.

NDMP (Network Data Management Protocol) NDMP support enables third-party applications that use NDMP to manage tape backup operations of system data. The ndmpcopy command carries out NDMP-compliant backups and restores. Security login restricts access to NDMP operations.

For information about NDMP, see the Data ONTAP Data Protection Tape Backup and Recovery Guide.

NVFAIL The nvfail option provides protection against data corruption by nonvolatile RAM (NVRAM) failures.

For information about NVFAIL, see the Data ONTAP Data Protection Online Backup and Recovery Guide.

SnapLock software (license required) SnapLock provides an alternative to traditional optical WORM (write-once-read-many) storage systems for nonrewritable data.

For information about SnapLock, see the Data ONTAP Data Protection Online Backup and Recovery Guide.

SnapMirror software (license required) System-to-system Snapshot mirroring enables you to mirror Snapshot copies on one storage system to a partner system. Should the original storage system be disabled, this ensures quick restoration of data from the point of the last Snapshot copy.

For information about SnapMirror, see the Data ONTAP Data Protection Online Backup and Recovery Guide.

SnapRestore software (license required) The SnapRestore feature performs fast restoration of backed-up data on request from Snapshot copies on an entire volume.

For information about SnapRestore, see the Data ONTAP Data Protection Online Backup and Recovery Guide.

Snapshot software Manual or automatically scheduled multiple backups (or Snapshot copies) of data using a minimal amount of additional disk space at no performance cost.

For information about how Data ONTAP organizes and manages data, see the Data ONTAP Storage Management Guide.

For information about Snapshot copies, see the Data ONTAP Data Protection Online Backup and Recovery Guide.

SnapVault software (license required) SnapVault combines Snapshot schedules and Qtree SnapMirror to provide disk-based data protection for NetApp storage systems. You can also install the Open Systems SnapVault agent on non-NetApp systems. This allows SnapVault to back up and restore data to those systems also.

Using SnapVault, you can periodically replicate selected Snapshot copies from multiple client NetApp storage systems to a common Snapshot copy on the SnapVault server. The Snapshot copies on the server become the backups. You decide when to dump data from the SnapVault server to tape. As a result, you avoid the bandwidth limitations of tape drives, you restore data faster, and you do not need to perform full dumps from primary storage, so you do not need to schedule a backup window.

For information about SnapVault, see the Data ONTAP Data Protection Online Backup and Recovery Guide.

SyncMirror (active/active configuration required) The SyncMirror software performs real-time RAID-level—that is, RAID4 or RAID-DP (RAID double-parity)—mirroring of data to two separate plexes that are physically connected to the same storage system head. If there is an unrecoverable disk error on one plex, the storage system automatically switches access to the mirrored plex.

For information about supported RAID levels and plexes, see the Data ONTAP Storage Management Guide. For information about SyncMirror, see the Data ONTAP Data Protection Online Backup and Recovery Guide.

Tape backup and restore Tape backup dump and restore commands enable you to back up system or SnapVault Snapshot copies to tape. Because the Snapshot copy, rather than the active file system, is backed up to tape, the storage system can continue its normal functions while the tape backup is occurring.

For information about tape backup, see the Data ONTAP Data Protection Tape Backup and Recovery Guide.

Virus scan support Data ONTAP provides support for third-party-scanning software for files accessed by CIFS clients.

For information about virus protection for CIFS, see the Data ONTAP Data Protection Online Backup and Recovery Guide.

vol copy This is fast block copy of data stored in volumes; it enables you to copy blocks of stored system data from one volume to another.

For information about volumes and vol copy, see the Data ONTAP Data Protection Online Backup and Recovery Guide.
