the tape and then rewinds it to the beginning. This command can be useful in some circumstances. By

retensioning on the tape, you can sometimes make an otherwise unusable tape op erational again.

NOTE:

If you need to retension tapes regularly to use them, consider servicing your tape drive or replacing

your tapes.

Eject You can use this command to eject media from the selected device or eject the media magazines

fromtheselectedlibrary. Somedevicemagazineswillnotbeejectable.

Restore Catalog The Restore Catalog command provides a quick method of restoring your current

catalog, for exa mple in case it has been corrupted. For example, you might use this command if the

Data Protector Express B a ckup Server has crashed. Use this command only when your current set of

media is intact. .

The Res tore Catalog command differs signiﬁcantly from the Impor t Media command in that it command

replaces the current catalog with the last known good catalog on that media. The Import Media

command, on the other hand, does not replace the current catalog; it only adds additional data to it.

The advantage of the Restore Catalog command is that it provides a quick and easy way to replace a lost

or corrupted D ata Protector Express catalog. You could use the Import M e dia command to restore a

corrupted catalog, but this process requires importing all of your media rather than simply reading the

media containing the catalog.

NOTE:

All informat

ion in the current Data Protector Express catalog will be lost when you use the Restore Ca talog

command. This command does not append data to the current catalog; it replaces the current catalog

with the last known good catalog on that media.

NOTE:

to start and stop the Data Protector Express service.

Clean Device The Clean Device command will run the backup device through a cleaning cycle.

This command is suppor ted only by libraries. If a device in a library provides notiﬁcation that it needs

cleaning and the library has a cleaning cartridge available, a cleaning cycle will be performed

automatically at the start of a backup job. If you are using a device that is not a library, you must

manually clean the device at the manufacturer’s suggested intervals.

To clean a device in a library, highlight the device and select Clean Device from the Command bar. Data

Protector Express will check to see if one of the slots holds a cleaning cartridg e. If it does, the cleaning

cycle will be p erformed in the background; if not, an error m essage is shown.

If the Clean Device command is missing, it is not available for your backup device. In this case, a

cleaning cycle can often be p erformed by manually inserting a cleaning cartridge into the backup device.
