Database rebuilds are likely to occur in each major, minor (single-dot), and release update (double-dot) version of NetBackup. Therefore, before upgrading to one of these versions of NetBackup, you must ensure that you have an amount of free disk space available that is equal to or greater than the size of the NetBackup database.
For default installations, you are required to have the free space on the file system containing the /usr/openv/db/data (UNIX) or <install_path>\Veritas\NetBackupDB\data (Windows) directories. If you have changed the location of some of the files in either of these directories, free space is required in those locations equal to or greater than the size of the files in those locations. Refer to the NetBackup Administrator's Guide, Volume I for more information about storing NBDB database files in alternate locations.
Note: This free disk space requirement assumes that you have already performed the best practice of completing a successful catalog backup before you begin the upgrade.
