A storage policy is a logical data management entity with rules that define the lifecycle management of the protected data in a subclient's content. It manages subclient data based on business requirements, even when the subclient's content resides on different servers in the CommCell. It defines a specific set of rules to manage the associated data; which data will be protected (which subclients); where it will reside (the data path and library); how long it will be kept (retention settings); and other media management options such as deduplication, compression, and encryption of the data in protected storage. The first storage policy defines the primary copy of the backed up data, which can be stored on local libraries for quick access. Additional copies of the backed data can be automatically created from existing copies already in the protected storage environment, to other libraries and locations for consolidation, auditing, business continuity, or ease of out-of-place recovery.
The following tables describes different types of storage policies:
|
Storage Policy Type |
Description |
|---|---|
|
Standard |
This storage policy will be used for following operations:
|
|
Incremental |
This storage policy will be used for following operations: Incremental and Differential Backups - All the subclients associated with any iDataAgent can use an incremental storage policy to perform incremental and differential backups. |
|
Disaster Recovery Backup |
This storage policy will be used for following operations: Disaster Recovery Backup and CommServe Disaster Recovery The software stores all information for the CommCell in a SQL database, and in the Windows registries. It is critical to be able to retrieve this information in the case of a disaster or system failure. This metadata and Windows registry data are backed up during a Disaster Recovery Backup. |
