Put policy managers to work to automate various rule-based data recovery functions.
Almost all storage hardware or software products support some form of rules-based policy storage management. The benefits of automated policy-based storage management include faster failover to standby and redundant systems, shortened recovery times and less human error. But before heading down the road to automated data protection for business continuity (BC) and disaster recovery (DR), it's crucial to thoroughly understand what types of policies various products support, where the policy manager resides and what it's capable of doing.
Automated policy management relies on rules (policies) that describe what actions to take or enforce for different events and conditions. Policies are enforced by policy managers also known as policy engines. It's not uncommon to have multiple and overlapping policy managers found in host-based software, network devices and storage systems.
