Managing Media

 

Copying Media

 

 

NOTE

When copying media, it is possible that the target medium reaches the

 

end of the tape before the source medium. This may happen if the source

 

medium was written in streaming mode and you make a copy on a busy

 

system or through a loaded network, which can create blank space where

 

the tape has stopped and started again. You can prevent this by enabling

 

tape padding when you format media. See “Formatting Media” on

 

page 108.

 

 

Moving Copies

Typically, you want to move the copies of the media to a safe place. See

 

“Vaulting Media” on page 140 and “Ejecting a Medium from a Device” on

 

page 137 for more information.

Exporting Copies

Exporting a medium removes all information regarding this medium

 

from the IDB. If you export the original medium, but one or more copies

 

of the medium exist, one of the copies becomes the original.

 

If you try to import the removed copy, but the original media are not in

 

the IDB, you have to import these media using the force option. See

 

“Importing Media” on page 113 for instructions.

Restoring from a

When you restore data, Data Protector prefers restoring from the

Copy

original media. However, if the original media are not available, but a

 

copy is available, the copy will be used for the restore.

 

If neither the original nor a copy is available in the device during restore,

 

Data Protector issues a mount request, displaying both the original and

 

the copy as the media required for restore. You can use any one of these.

 

If you perform a restore using a standalone device, you can choose to

 

restore from the copy rather than from the original. To do this, insert the

 

copy in the device that will be used for the restore, or select the device

 

containing the copy. However, if you perform a restore using a library

 

device and the original is in the library, Data Protector will use it for the

 

restore.

 

For detailed instructions on how to restore data from the media archive,

 

see “Vaulting Media” on page 140.
