Dell NetWorker 19.9 Administration Guide

Raw partitions

The NetWorker software must have exclusive access to a file system to perform a raw backup. Close as many applications as possible before doing a raw disk backup. If the raw partition contains data that are managed by an active database management system (DBMS), ensure that the partition is offline and the database manager is shut down. For greater flexibility when backing up partitions that contain DBMS data, use a NetWorker Module application.

Raw partitions on Windows

Back up raw disk partitions on Windows by specifying the raw disk partition in a save set with the save command. Identify the raw partition as a physical drive or logical drive. For example:

save -s NetWorker_server_name -o VSS:*=off \\.\e:
save -s NetWorker_server_name -o VSS:*=off \\.\PhysicalDrive0

Raw partitions on UNIX

Back up raw disk partitions on UNIX by using the rawasm directive.

Raw partitions on Linux

NetWorker can only save an unbound Linux raw device. When you back up a Linux raw disk partition, you must specify /dev/sd or /dev/hd in the Save set attribute on the General tab of the Client Properties dialog box for the Linux Client resource. The backup fails if you use the /dev/raw device.
