Parts of the NetBackup catalog
The NetBackup catalog resides on the NetBackup primary server. It manages and controls access to the following types of data:
Image metadata (information about backup images and copies).
Backup content data (information about the folders, files, and the objects in a backup (
.ffiles)).NetBackup backup policies.
NetBackup licensing data.
The NetBackup error log.
The client database.
Cloud configuration files.
The catalog consists of the following parts:
NetBackup stores information in the NetBackup database (NBDB). The metadata includes information about the data that has been backed up, and about where the data is stored.
The image database.
The image database contains information about the data that has been backed up.
NetBackup configuration files.
The key management service (KMS) configuration files
For more details on the KMS configuration, see the NetBackup Security and Encryption Guide.
NetBackup is sensitive to the location of the primary server components. Running any part of NetBackup (the binaries, the logs, the database, the images) on a network share (NFS, for example) can affect performance of even normal operations. NetBackup can be CIFS-mounted on SAN or NAS storage as long as the average I/O service times remain less than 20 milliseconds.
The storage must also meet certain conditions to ensure data integrity in the NetBackup catalog.
The order of file writes must be guaranteed.
When a write request is issued, the write must complete to the physical storage. The write request must not merely be buffered when the SAN or the NAS returns from the write call.
