How policies work in Data Lifecycle Manager

In Data Lifecycle Manager, you create policies to establish the rules you want applied to your replication and disaster recovery jobs. The policy rules you set can include which cluster is the source and which the destination, what data is replicated, what day and time the replication job occurs, the frequency of job execution, bandwidth restrictions, etc.

When scheduling how often you want a replication job to run, you should consider the recovery point objective (RPO) of the data being replicated; that is, what is the acceptable lag time between the active site and the replicated data on the destination. Data Lifecycle Manager supports a one-hour RPO: data is preserved up to one hour prior to the point of data recovery. To meet a one-hour RPO, you must consider how long it takes to replicate the selected data, how often the data is replicated, and network bandwidth capabilities.

As an example, if you have a set of data that you expect to take 15 minutes to replicate, then to meet a one-hour RPO, you would schedule the replication job to occur no more often than every 45 minutes, depending on network bandwidth.
