Hi,

I have heard people talking about "Business Copy".

Is it a name of the product or technology ?

Thanks,

Both.

Functionality depends on the storage hardware.

Principally it is making a copy of an existing LUN.

So you can duplicate the data device of your database for testing - just an example.

It is the name of a product but is synonymous to technology in greater terms.
There will be products with different names from different vendors which will perform the functionality that HP Business copy makes.
IBM - Flashcopy
Netapp - SnapClone

The functionality is available for HPs VA, EVA and XP arrays. It's normally a licenced feature. The name and the way to do it may be different, but the result is the same - a copy of a LUN.

Shalom Shiv,

We're specifying an EVA-4000. Business copy is a feature that permits us to create an instant delta or change on a portion of the disk, permitting us to take backups in seconds.

Business Copy is the name of the functionality built into the VA, EVA and XP Storage Arrays that aside for "making a copy" of a LUN... allows direct access to data with minimal impact to performance and with minimal downtime to your data. BC allows for automated local data replication (the snapclone process) of data, easy management of replicated data and simple local data restoration.

HP StorageWorks Business Copy VA is an array based software product that allows customers to create up to 1023 non disruptive high performance, local business copies of any active application volume or LUN for the VA7000 family array within the array while benefiting from full RAID protection for the business copies. These LUN copies can be used by another application or system for a variety of purposes, including batch processing and backup. You can create up to 1023 Business Copy LUNs with the VA7000 family arrays. Business Copy VA is fully integrated into and enabled through the HP Command View SDM software interface.

Features:

â ¢ Business critical data can be executed in parallel to enhance efficiency and cost effectiveness.
â ¢ Instantly creating point in time copies of source LUNs, scheduling backup activities, and maintaining I/O Host performance because all LUN creation and activity is handled directly by the array.

hi;

business copy is the name of feature that allows local copies in eva. it licenced and gives the abilities to take snapclone and snapshot of vdisks. Snapclone is the point-in-time independent copy of a vdisk. Because all data is copied from the source disk. and snapclone can be created in different disk group than the source.Snapshot is depented, point-in-time copy of a vdisk. Data is not copied to snapshot, Just pointers to data in vdisk is created. if data changes after taking the snapshot, point-in-time data is copied to snapshot. There two types of snapshot: Demand Allocated and Fully Allocated. Demand allocated does not allocate space as source vdisk, but fully allocated allocates the exact space. Snapshot is created in the disk group of source vdisk. Snapshot's raid level must be the same level or lower( raid 1 > raid 5 > raid 0). if demand allocated snapshot does not have enough space when growing, eva stops writing both to snapshot and the source.

Generally snapclone is used for testing, data mining etc., snapshot is used for temporary needs like back up. With snapshot you don't need to stop database for backing up i.e.

This is a software for local replication.
As soon as purchasing it you will find a license key that you should input it on your stotage also you can purchase a media pack for using this new ability of stotrage for replication.
