Table: NDMP default options for EMC backup and restore

Item

Description

Backup method

Specifies the backup level. Level 0 provides a full backup. Levels 1 through 9 provide various levels of incremental backups. Level 1 backup method backs up new or modified files since the level 0 backup. Level 2 backup method backs up new or modified files since the level 1 backup, and so on.

Backup type

Determines the backup type for backup jobs.

The following backup types are available:

  • VBB

  • Dump

Back up with integrated checkpoints (SnapSure)

Enables Backup Exec to create a backup set that uses the EMC SnapSure feature.

For more information about SnapSure, see your EMC documentation.

Enable file history

Allows for the recovery of selected subsets of data from the backup history. If you uncheck Enable file history, file history data is not generated, but backup time may be reduced. This option is selected by default.

Enable Direct Access Recovery

Enables Backup Exec to use Direct Access Recovery (DAR) during the restore job. With DAR-enabled recovery, Backup Exec can specify the exact location of a file in a backup data stream. The NDMP server can then read the data applicable to the single file being restored. This practice reduces the amount of information that is processed and significantly reduces recovery time. If DAR is not available, the restore may take significantly longer.

Preserve tree

Restores the data with its original directory structure intact. This option is enabled by default. If you clear this option, all data in the directories and the subdirectories is restored to the path you specify in the File Redirection dialog box.

See File Redirection restore options .

Note:

This option affects the restore of EMC data only. For non-NDMP data, use the Preserve tree option on the General Restore Job Properties dialog box.

See General options for restore jobs.

Restore over existing files

Overwrites files on the target resource that have the same name as files that are being restored. Use this option only when you are sure that you want to restore an older version of a file.
