Dell PowerStore Protecting Your Data
Data protection
PowerStore provides various means for protecting your data:
- Local protection - Create snapshots (point-in-time copies) of volumes, volume groups, virtual machines, or file systems on the PowerStore system .
- Remote protection - Replicate data to a remote system, or mirror the data using metro volumes for redundancy if there is a disaster.
- Remote backup - Back up volumes and volume groups directly from PowerStore to a PowerProtect DD.
PowerStore enables you to create custom protection policies, which are sets of rules for snapshot creation, replication, and remote backup, and assign them to storage resources. Protection policies apply the defined rules on the storage resource, providing it with local protection, remote protection, and remote backup.
NOTE:Remote backup rules can be applied only to volumes and
volume groups.
NOTE:Protection policies that include a replication rule cannot be assigned to metro volumes.
See
Using protection policies with metro.
NOTE:As of version 3.x, protection policies cannot be applied to virtual volumes (vVols) based virtual machines. See
Virtual volumes replication.
PowerStore also enables you to configure standard backup for NAS servers using NDMP. For details, see Enable NDMP backup.
