Block Backup
Catalogic DPX Block Data Protection assures minimal business interruption and maximum data integrity in the event of any data resource loss – large or small. The Catalogic DPX Block Data Protection utilizes proprietary Catalogic technologies for block-level backup and fast, reliable recovery.
Block backup is the backup component of the Catalogic DPX Block Data Protection. In the desktop interface, block backups are implemented through the Block Backup Wizard. In the web interface, block backups are defined in the Job Manager section just like any other backup type.
NetApp Deduplication Features Considerations
Block backups interact with the NetApp deduplication (Advanced Single-Instance Storage) for the NetApp storage systems.
The Catalogic DPX Block Data Protection processing automatically invokes block deduplication after the data transfer; all data at the root of the volume is deduplicated at that time. Due to differences in deduplication support between Data ONTAP versions, it is strongly recommended that Data ONTAP 8.0.1 or later be used with 64-bit aggregates to maximize deduplication and processing efficiency.
Deduplication is a feature that is enabled per volume. It is recommended to start deduplication backup jobs on newly created empty NetApp volumes as the NetApp deduplication will not deduplicate data already retained in existing snapshots. For volumes with A-SIS enabled, deduplication processing is automatic and occurs immediately after the backup job completes. Scheduled volume deduplication should be disabled within Data ONTAP as the backup automatically invokes the deduplication process, and any additional scheduling is redundant and an unnecessary drain on system resources. There is no option to defer deduplication until a later time.
NetApp deduplication requires a NetApp A-SIS license.
