The SAM file system can be viewed as a cache: All the files are kept in the cache until it fills up, at which point the

oldest or least recently accessed files are released

. If a released file is later required, the data is quickly brought back

from the archives by the SAM's stager

process. These actions are transparent to applications with the benefit that the

contents of the file system are managed so that it should never overflow

. However, SAM can be configured so that a

file is never released from the cache.

The benefits of using Storage Archive Manager with Enterprise Vault include:

● Tiered Storage: Customers looking for an email archiving solution are often interested in using tiered storage

as well. The customer's first objective is to relieve congestion on the email servers and related storage

subsystems by migrating content from the primary email storage to cheaper archival storage, but in time the

archival storage itself becomes congested. The ability of Storage Archive Manager to seamlessly migrate data

from its Vault Stores to other storage tiers resolves this problem.

● Transparent Backup of Archived Data: SAM can make at least one, and up to four, copies of the data archived

by the Enterprise Vault software. These copies can be made to local or remote tape disk, tape archives, or

both. Archiving policies can be customized to suit a customer's business requirements.

● Continuous Backup and Quick Restore: Backing up and restoring file systems containing large numbers of files

can be a long process using traditional backup software. In a SAM solution, the file system backs itself up

continuously to disk archives, tape archives, or both without the requirement for a backup window. Also, a

SAM file system can be brought back online very quickly following a hardware failure or when the file system

is being migrated to another platform because only the metadata of the SAM file system needs to be restored;

the files themselves can all be left in the archives.

3 It is still necessary to size a solution according to the amount of data that will be archived and the customer's retention policies. This

information is gathered as part of the Enterprise Vault sales process.
