Oracle Intelligent Policy - Storage and Retention

This topic describes storage and retention properties of the Oracle Intelligent Policy.

See the NetBackup Administrator's Guide, Volume I.

Table: Storage and retention behavior

Property	Description
Policy is a snapshot type	If the policy is a snapshot type, the following are the possible scenarios of the retention behavior: If the schedule does not override the policy storage unit, and the policy storage unit is a non-snapshot SLP, the SLP determines the retention period and the policy uses the policy storage unit. If the schedule does not override the policy storage unit and the policy storage unit is not an SLP, the schedule determines the retention period, and the policy uses the policy storage unit. If the schedule does override the policy storage unit with an SLP, and it is not a snapshot SLP, the override storage unit takes precedence over the policy storage unit, and the SLP determines the retention period. If the schedule overrides the policy storage unit with a snapshot SLP, the policy storage unit must be a non-snapshot SLP. The SLP on the policy storage unit determines the retention period for the streamed data. Also, the SLP on the schedule determines the retention for the snapshot data.
Policy is not a snapshot type	If the policy is not a snapshot type, the following are the possible scenarios of the retention behavior: If the schedule does not override the policy storage unit and the policy storage unit is not an SLP, the schedule determines the retention period. If the schedule does not override the policy storage unit and the policy storage unit is an SLP, the SLP determines the retention period. If the schedule overrides the policy storage unit, and the schedule storage unit is not an SLP, the schedule determines the retention period. If the schedule overrides the policy storage unit and the schedule storage unit is an SLP, the SLP determines the retention period.

Property

Description

Policy is a snapshot type

If the policy is a snapshot type, the following are the possible scenarios of the retention behavior:

If the schedule does not override the policy storage unit, and the policy storage unit is a non-snapshot SLP, the SLP determines the retention period and the policy uses the policy storage unit.
If the schedule does not override the policy storage unit and the policy storage unit is not an SLP, the schedule determines the retention period, and the policy uses the policy storage unit.
If the schedule does override the policy storage unit with an SLP, and it is not a snapshot SLP, the override storage unit takes precedence over the policy storage unit, and the SLP determines the retention period.
If the schedule overrides the policy storage unit with a snapshot SLP, the policy storage unit must be a non-snapshot SLP. The SLP on the policy storage unit determines the retention period for the streamed data. Also, the SLP on the schedule determines the retention for the snapshot data.

Policy is not a snapshot type

If the policy is not a snapshot type, the following are the possible scenarios of the retention behavior:

If the schedule does not override the policy storage unit and the policy storage unit is not an SLP, the schedule determines the retention period.
If the schedule does not override the policy storage unit and the policy storage unit is an SLP, the SLP determines the retention period.
If the schedule overrides the policy storage unit, and the schedule storage unit is not an SLP, the schedule determines the retention period.
If the schedule overrides the policy storage unit and the schedule storage unit is an SLP, the SLP determines the retention period.

The following are examples of the Oracle Intelligent Policy storage and retention behavior for snapshot-based policy types.
