NetBackup™ Upgrade Guide

Database user, port, and disk space requirements

For Linux environments, the new NetBackup database must have a non-root user for operations. You are prompted for the non-root user if the root user starts the NetBackup daemons. The username must meet the criteria shown:

  • Root accounts are not allowed.

  • Accounts with access to the sudo utility are not allowed.

  • The username must be 1-31 characters.

  • The username must contain only English characters.

  • Do not use the nbwebsvc user as the scale-out database user.

  • For more details, see: https://support.cohesity.com/s/article/article-100053091

If the NetBackup daemons already start with a non-root user this same account is used to run the NetBackup database.

The new database has a connection pooler service that by default uses port 13787. Confirm that this port is available for database operation before upgrade. Failure to provide valid port numbers renders NetBackup unusable until the port issues are resolved.

If this port is not available, you can change the value with the answer file during a Linux upgrade. The Linux interactive upgrade does not have a prompt. For a Windows primary server, you can change the port value by selecting the Custom installation path during upgrade. More information about the answer file is available:

See About the NetBackup answer file.

During upgrade, additional disk space is required for the conversion. The space is necessary to create the new PostgreSQL databases as well as to store the temporary .dat files. NetBackup expects the new database to be approximately the same as the old database. The temporary .dat files require space equivalent to size of the current ASA .db files.

The additional disk space for the NetBackup database conversion is only required when you upgrade from pre NetBackup 10.2 to NetBackup 10.2 and later. Once the database is converted, this additional disk space is not required.

On Linux primary servers, the database files are in the /usr/openv/db/data directory. On Windows primary servers, the database files are in the install_path\NetBackupDB\data directory.
