Snapshot policies provide automated scheduling of SnapVX snapshots using a highly available and flexible policy engine that runs internally on the storage array. Snapshot policies can be managed through Dell EMC Unisphere for PowerMax, REST API, and Solutions Enabler.
Snapshot policies can be customized with rules that specify when to take snapshots, how many snapshots to take, and how long to keep each snapshot. Compliance requirements can also be specified to send alerts if the rules of a policy are not being met. Applications can be protected by multiple policies with differing schedules and retention parameters according to the requirements of the business. Each policy can protect many applications, even protecting a mix of open systems and mainframe applications.
Snapshot policies provide reliable protection for applications in an automated fashion that requires little to no maintenance by the business. Administrators can manually take snapshots of applications that are protected by snapshot policies to satisfy on-demand requirements.
