Use cases for long-term data retention
The following are the use cases for long-term data retention (LTR) using Access Appliance:
Use Case: Access Appliance with Veritas Data Deduplication
Veritas Data Deduplication technology is installed on top of Access Appliance and integrates with NetBackup. It catalogs and organizes incoming deduplicated backup data and stores it on Access Appliance storage.
MSDP deduplicates the primary backup data and stores it on the NetBackup server.
The same deduplicated data is sent to Access Appliance for long-term retention purpose using SLPs through duplication jobs.
Veritas Data Deduplication can also act as a source or destination while replicating deduplicated data using Auto Image Replication (AIR).
Note:
Veritas supports a deduplication pool of size upto 2790822931980000 bytes (approximately 2.478 PiB) if the Veritas Data Deduplication version is 20.4.0.1 or later. If the Veritas Data Deduplication version is 19.0.1, you cannot create a deduplication pool of size greater than 1392125484720000 bytes (approximately 1.236 PiB).
If the Veritas Data Deduplication version is 19.0.1 and you want to use 2.478 PiB of storage, the following configurations are possible:
Configure two instances of Veritas Data Deduplication with 1.236 PiB (approximately) storage each.
Configure MSDP-C with four buckets of size 600 TiB each.
Configure Veritas Data Deduplication with 1.236 PiB (approximately) storage and configure MSDP-C with two buckets of size 600 TiB each.
Use the virtual IP of one node for Veritas Data Deduplication and use the virtual IP of another node for MSDP-C.
Use Case: Access Appliance with MSDP-C
MSDP deduplicates the primary backup data and stores it on the NetBackup server.
The same deduplicated data is moved to Access Appliance through SLP using MSDP-C.
See Configuring Access S3 bucket with NetBackup MSDP-C.
Use Case: Access Appliance as an S3 connector
Backup data is stored in non-deduplicated format on the NetBackup server as primary backup. The same primary backup data is moved to Access Appliance through SLP over the Access Appliance S3 protocol.
Or
MSDP duplicates the primary backup data and stores it on the NetBackup server.
The deduplicated data is rehydrated and then moved to Access Appliance through SLP over the Access Appliance S3 protocol.
Figure: Backup data stored in non-deduplicated format on the NetBackup server as primary backup and the same backup data duplicates to Access Appliance over Access S3 protocol.
Note:
Configurations and use cases beyond storing copies for long term retention periods require a Support Exception. Please contact your Veritas representative for details on the Support Exception approval process.
