Symantec Backup Exec

Device

Designates a device pool, a robotic library drive, a stand-alone drive, a backup-to-disk folder, a removable backup-to-disk folder, or other type of supported storage device to which you want to send backup data.

Use client-side deduplication

Enables a remote computer that is configured as a Remote Agent for Deduplication to deduplicate data and then send only the unique data directly to the deduplication device that is selected in the Device field. This option is selected by default when you select an OpenStorage device or a deduplication storage folder in the Device field.

This option is available only if the Deduplication Option is installed and a deduplication device is selected in the Device field.

See About client-side deduplication.

Use media server deduplication

Enables the media server to deduplicate data. Media server deduplication reduces the size of backups, which reduces storage requirements. If the media server does not support deduplication, the data is deduplicated on an intelligent disk device, such as Symantec PureDisk or a device from a third-party vendor.

This option is available only if the Deduplication Option is installed and a deduplication device is selected in the Device field.

See About the Deduplication Option.

Restrict backup of the selection list to devices on the following media server or media servers in a pool

Specifies if you want a job to run on devices on a specific managed media server or on devices that are on a group of managed media servers.

This check box displays only if you have the Central Admin Server Option installed. This is an additional filter that lets you control where certain jobs are delegated. For example, to always run backups of Exchange databases only on the devices that are attached to managed media servers in a pool named Exchange Backups, select this option, and then select the Exchange Backups media server pool.

Media set

Specifies the media set for the backup. If you select Overwrite, the media in the drive is overwritten if the media is scratch, or if its overwrite protection period has expired. If allocated or imported media are in the drive, they may also be overwritten depending on the Media Overwrite Protection Level that is set.

If you selected one of the append options, the backup will be added to an appendable media (if one exists).

Overwrite media

Places this backup on an overwritable media. Make sure that appropriate media is in the stand-alone drive or drive pool you select in the Device field in this dialog box.

The media in the drive is overwritten if the media is scratch or recyclable (its overwrite protection period has expired). If allocated or imported media are in the drive, they may also be overwritten depending on the Media Overwrite Protection Level that is set.

Depending on your configuration, overwritable media is selected from scratch media or recyclable media.

See How Backup Exec searches for overwritable media.

If the media in the drive is not overwritable, an alert appears requesting that you insert overwritable media.

Append to media, overwrite if no appendable media is available

Appends this backup to the media set listed in the Media Set field in this dialog box. The backup set is appended if an appendable media is available in the selected media set; if not, an overwritable media is used and added to the media set.

If an append job fills a media, the job continues on another piece of overwritable media.

If the media in the drive is not overwritable, an alert appears requesting that you insert overwritable media.

Append to media, terminate job if no appendable media is available

Appends this backup to the media set listed in the Media Set field in this dialog box. The backup set is appended if an appendable media is available in the selected media set; if not, the job is terminated.

Eject media after job completes

Ejects the media in the drive when the operation completes.

Retension media before backup

Runs the tape in the drive from beginning to end at a fast speed, which helps the tape wind evenly and run more smoothly past the tape drive heads. Retensioning is primarily for Mini Cartridge and quarter-inch cartridges and is not supported on most oth
er types of tape drives.

Use Write once, read many (WORM) media

Specifies the use of WORM (write once, read many) media for this backup job. Backup Exec confirms that the destination device is or contains a WORM-compatible drive, and that the WORM media is available in the drive. If WORM media or a WORM-compatible drive is not found, an alert is sent.

See About WORM media.

Maximum number of devices to use for resources that support multiple data streams

Specifies the number of devices that this backup job can use. Only one device per stream can be used.

Minimum number of devices, terminate job if fewer devices are available

Specifies the minimum number of devices that can be used for this backup job. If the minimum number of devices is not available, the job ends without completing.
