How to plan for an upgrade to NetBackup 9.0
Several factors must be considered when you prepare for an upgrade to NetBackup 9.0.
The NetBackup 8.1 upgrade includes a rolling conversion of the Media Server Deduplication Pool (MSDP).
By default, the rolling conversion is performed when the system is not busy. In other words, the conversion runs when backups, restores, CRQP, CRC checks, compaction, etc. are not active. This conversion is not expected to affect normal system operations. After the rolling conversion is finished, there is no difference between the converted system and a new installation. More information about the rolling conversion is available.
If you plan to use role-based access control (RBAC), you must designate a security administrator. More information is available:
Beginning with NetBackup 8.0, the NetBackup master server includes a configured Tomcat web server to support critical backup operations. This web server operates under user account elements with limited privileges. These user account elements must be available on each master server (or each node of a clustered master server). More information is available:
It is recommended that you save the details of the user account that you use for the NetBackup Web Services. A master server recovery requires the same NetBackup Web Services user account and credentials that were used when the NetBackup catalog was backed up.
If the NetBackup PBX is running in secure mode, please add the web service user as authorized user in PBX. More information about determining PBX mode and how to correctly add users is available.
Upgrades of NetBackup 8.2 UNIX clusters with NAT enabled incorrectly identify the NAT state. As a result, NAT is disabled after the upgrade to 9.0. After you complete the NetBackup 9.0 upgrade, you must turn NAT on again. More information is included in the post-upgrade procedure.
It is not supported the installation or upgrade of the NetBackup database on a
btrfs file system. If the NetBackup database resides on a
btrfs file system, move the database to a supported file system (such as
xfs) before you start the upgrade. The database files reside on the master server in the directories under
/usr/openv/db. More information about moving the database before an upgrade is available. See Preinstall procedure for upgrading to NetBackup 9.0.
Starting with NetBackup 8.3, the Java GUI and the JRE packages are optional for UNIX, Linux, and Windows media servers and UNIX and Linux clients.
As with previous releases, the Java GUI and JRE packages are installed automatically on all master servers because they are required. The Java GUI and the JRE are not part of the default installation on Windows clients. Install the Java Remote Administration Console if you require this functionality on your Windows clients.
The various NetBackup upgrade methods allow the user the choice to upgrade or uninstall the Java GUI and JRE packages. More information about installing or removing the Java GUI and the JRE after upgrade is available.
NetBackup uses security certificates to authenticate NetBackup hosts for secure communication. The security certificates conform to the X.509 Public Key Infrastructure (PKI) standard. A NetBackup master server acts as the certificate authority (CA) and issues digital certificates to hosts. NetBackup now supports the following certificate key sizes: 2048 bits, 4096 bits, 8192 bits, and 16384 bits.
With a NetBackup 9.0 upgrade, new root CA with 2048 bits key strength is deployed. To use a certificate key size larger than 2048 bits, set the NB_KEYSIZE environment variable on the master server before you start the installation.
NB_KEYSIZE = 4096
The NB_KEYSIZE can only have the following values: 2048, 4096, 8192, and 16384.
For more information about CA migration and certificate key sizes, see the NetBackup Security and Encryption Guide.
