Pathlight VX Site Preparation Guide 43

•The Minutes Before Copy parameter refers to the number of minutes that virtual media must be

idle before the Pathlight VX backup application is done using it. For example, if media is used for

multiple backup jobs, but it might be unloaded between jobs, then this parameter should be set to

0 minutes. If the media is usually filled during a single job, or is only used for a single job, then this

parameter should be set to a low value. For virtual media that does not need to be copied to physical

media (tape), check the Never Copy box.

•The Never Copy (Y/N) parameter allows you to specify that you never want to make Disk Extension

copies. The default value is N, which means that you do not want to enable the Never Copy setting,

because you want to make Disk Extension copies.

•The Virtual Media on Disk: Never Remove (Y/N) parameter allows you to specify whether data

should ever be removed from the Pathlight VX disk. If data should always reside on disk, check the

Never Remove box. If data should be removed from disk when the disk threshold (watermark) is

reached, do not check the box. The default value is N, which means that you do not want to enable

the Never Remove setting, because you want to migrate virtual tape to physical tape.

Note

Data removal from disk only occurs when the disk fills to more than 85%

capacity. When this internal threshold is reached, Pathlight VX clears out

virtual media until the disk usage falls to less than 75% of capacity. To

determine if specific virtual media is still on disk, refer to the On Disk

parameter of the Detail Media Report, accessed from the Virtual Media

Summary Report.
