Managing data transfers

Scheduling backups

All data transfers are managed by Data ONTAP in response to requests from the NetBackup interface. Backup policies, however, are scheduled using the NetBackup Administration Console. Policies are a set of rules that define backup criteria for a particular client or group of clients. For example, NetBackup policies control backup intervals, number of versions, and how long to retain a particular archive.

For more information, see the VERITAS NetBackup System Administrator's Guide.

File naming

Default file system naming for NBU NearStore qtree images is as follows:

.nbu_image_data is a special qtree that contains information specific to the tar images associated with each qtree.

nbu_clientname_policyname_suffix is the qtree naming convention where each name is specific to NetBackup client and policy settings.

Each qtree contains a .nbu_no_access subdirectory. NBU NearStore in Data ONTAP 7.1 does not support viewing the contents of this subdirectory from the storage system console. However, you can view the backup files from the NetBackup Administration Console.

For more information, see the VERITAS NetBackup System Administrator's Guide.

Monitoring qtree status

To confirm that a destination qtree has been created on the storage system, use the qtree status command to display NBU volume status.

system*> qtree status

Checking the status of a data transfer

To check the status of a data transfer, use the snapvault status command. This display can be used to view recent backup activity and confirm transfer status.

system*> snapvault status

Snapvault secondary is ON.
