What do dissimilar policies provide in IBM Spectrum Protect node replication between source and target...

In IBM Spectrum Protect node replication, dissimilar policies provide the ability to replicate client data between source and target servers with differing retention settings.

Dissimilar policies allow for more granular control over the retention settings of client data on the target server, which can be different from the retention settings on the source server. This means that the data can be kept for a longer or shorter period of time on the target server compared to the source server, based on the specific retention policies configured for the target server.

According to IBM documentation1, dissimilar policies provide the ability to use different management policies on the target replication server than on the source replication server. This means that you can have different retention periods, storage pools, or data types for replicated data on the target server. You can enable this feature by using the SET DISSIMILARPOLICIES command.
