About NetBackup installation requirements
This release of NetBackup may contain changes to the minimum system requirements and procedures that are required for installation. These changes affect the minimum system requirements for both Windows and UNIX platforms. Much of the installation instructional information in the NetBackup Release Notes is provided for convenience. Detailed installation instructions are found in the NetBackup Installation Guide, the NetBackup Upgrade Guide, and the NetBackup Getting Started Guide.
Before you upgrade the NetBackup server software, you must back up your NetBackup catalogs and verify that the catalog backup was successful.
Database rebuilds are likely to occur in each major, minor (single-dot), and release update (double-dot) version of NetBackup. Therefore, before upgrading to NetBackup 8.1.1, 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. That means for default installations, you are required to have that amount of free space on the file system containing the
<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.
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.
Master and media servers must have a minimum soft limit of 8000 file descriptors per process for NetBackup to run correctly.
For more information about the effects of an insufficient number of file descriptors, refer to the following tech note on the Veritas Support website:
To install NetBackup on Windows 2008/Vista/2008 R2/ UAC-enabled environments, you must log on as the official administrator. Users that are assigned to the Administrators Group and are not the official administrator cannot install NetBackup in UAC-enabled environments.
To allow users in the Administrators Group to install NetBackup, disable UAC.
NetBackup master and media servers exchange server version information at startup, and every 24 hours. This exchange occurs automatically. During startup after an upgrade, the upgraded media server uses the vmd service to push its version information to all of the servers that are listed in its server list.
Veritas recommends that you have the master server services up and available during a media server upgrade.
All compressed files are compressed using gzip. The installation of these files requires gunzip and gzip, so make sure that they are installed on the computer before you attempt to install NetBackup. For all UNIX platforms except HP-UX, the binaries are expected to be in /bin or /usr/bin and that directory is a part of the root user's PATH variable. On HP-UX systems, the gzip and gunzip commands are expected to be in /usr/contrib/bin. Installation scripts add that directory to the PATH variable. These commands must be present to have successful UNIX installations.
