The following best practices apply to using the Deduplication Option with the Central Admin Server Option:

• Create a deduplication disk storage device on managed Backup Exec servers in a CASO environment.

• Do not run jobs that use a deduplication disk storage device on a central administration server. Instead, assign backup jobs to managed Backup Exec servers and select a Backup Exec server pool as a setting for the destination device.

• Share the deduplication disk storage devices that are on multiple managed Backup Exec servers with the Backup Exec server that is the replication target. This provides the best use of optimized duplication. For example, the main office site that has a managed Backup Exec server deployment shares the deduplication disk storage device with the central administration server at a remote site for disaster recovery purposes.

• Use the following recommendations for optimal catalog placement:

  • For local LAN deployments, use replicated catalogs.

  • For site-to-site optimized duplication, use distributed catalogs.

• Do not use Backup Exec server pools as device targets in standalone backups. This prevents duplicate data from being hosted on multiple managed Backup Exec servers.

• Subdivide the remote computers that are enabled for direct access sharing among the servers that host the deduplication disk storage folders to best optimize several managed Backup Exec servers at a single site. For example, a large site with two managed Backup Exec servers and 10 remote computers should split the remote computers evenly between the managed Backup Exec servers.

• Limit the sharing of remote computers that are enabled for direct access sharing with other Backup Exec servers that use deduplication disk storage. This prevents duplicate data from being hosted on multiple backup servers.

• Verify all backup data.

  Note:

  Due to the rehydration of data during the verify process, slow performance over Wide Area Networks can be expected if you use optimized duplication with verify templates.
