The BACKGROUNDCOPY parameter can be specified on the GLOBAL command. It has a matching site option, &BACKGRND.

The BACKGROUNDCOPY and MODE parameters serve the same purpose and cannot be specified together. They are mutually exclusive.

Syntax

BACKGROUNDCOPY({Yes|No|NOCOPYRD|VSE})

You can specify the NOCOPYRD keyword as follows:

• NOBACKGROUNDCOPYONREAD
• NOBGCOPYONREAD
• NOCOPYONREAD
• NOCOPYREAD
• NOCOPYRD

Options

No

Establishes a snap relationship where tracks are copied from the source to the target when tracks are updated on the source or target or read on the target. Additional updates to the same source track are not copied.

NOCOPYRD

Specifies that the background copy occurs only when a track is changed on the source or target. This causes the original source track to be copied to the target. Additional updates to the same source track are not copied to the target. A read of the source or target track does not cause the track to be copied.

VSE

This option allows you to run a background copy function when in VSE copy mode. This option is the same as MODE(VSE).

Yes

(Default) Enables background copy.
