Advanced Copy OPC
One Point Copy (OPC) enables the creation of a high speed copy of an entire business data volume at any specific point in time.
Unlike EC, with its data synchronization (mirroring) capability the copy volume created by OPC is always separate from the business volume (a point in time copy) and never reflects ongoing updates to the business data.
This means the copy is a snapshot of the business data at the time the OPC request is issued and as such can be backed up to a tape device in parallel with the business operation.
However for subsequent backup, OPC requires that all the data is copied once again. To copy only updated data, QuickOPC[1] is provided.
- [1]QuickOPC is not available with GlobalServer.
Applicable Operation
- Any operations where data copies are required including before/after heavy load transactions such as batch updating.
- Performing a backup.
- Performing system test data replication.
- Restoring backup data. (restoration after replacing a drive when the copy source drive has failed）
Benefits
- High-speed backup and near real-time disk-to-disk-to-tape backup extends business operation hours and availability.
