Advanced Copy function Partial copying - SnapOPC / SnapOPC+

SnapOPC only copies the "before" picture of data being updated, to the copy volume. By only copying data subject to change, copy volume capacity can be much smaller than the original business data volume. In addition, SnapOPC+ provides generation management of the updated data. The difference between SnapOPC+ and SnapOPC is that SnapOPC+ updates data only as history information while SnapOPC stores the data redundantly. Logging as history information can provide disk based generation backup using a smaller copy volume capacity.

ETERNUS DX100 S3, DX200 S3, DX60/DX60 S2/DX60 S3, DX80/DX80 S2, DX90/DX90 S2 and DX200F provide 8 sessions of SnapOPC+ for free as standard.

The figure below is a description of SnapOPC+ operation.

Applicable Operation

• Backup of operations that have relatively few updates such as file servers.

Benefit

• Enables efficient copy retention as the overall copy volume capacity is much smaller.
