NetBackup multi-version co-existence: what combinations of 7.x, 6.5.x, 6.5, 6.0, 5.1, 5.0 client, media, and master servers are compatible?

Symantec NetBackup maintains a policy by which they can deliver various levels of releases to accommodate customer needs. The following list defines the various release types and the version number schemes associated with each type. NetBackup products and the NetBackup Appliance products use this same process.

  • A major release is the first in a series of single-dot releases such as 2.0 or 7.0. This type of release contains new features, new supported platforms, and a complete set of the latest product documentation. These releases are available from FileConnect.
  • A minor release is a single-dot release that follows a major release, for example, 2.1, 7.1, 7.5, and so forth. This release type contains much of the same requirements as a major release. It contains a smaller set of new features and enhancements, platform proliferations, and a complete set of updated documentation. These releases are available from FileConnect.
  • A release update is a double-dot release, for example, 2.0.1, 7.0.1, 7.0.2, and so forth. This release type may contain a few new features and enhancements as well as a many product fixes. Only those documents that are applicable to the new features or enhancements are updated and republished. These releases are available on the Support website and are listed below.
  • A maintenance update is a triple-dot release, for example, 2.0.0.1, 7.1.0.2, 7.5.0.1, and so forth. This release type is comprised of a small number of fixes that are developed to address issues in either a major, minor, or release update. This release type only contains fixes to known issues and does not contain new features or enhancements to NetBackup. These releases are available on the Support website and are listed below.

NetBackup releases are cumulative releases, features and fixes released in one release are included in the next release. For example,

  • NetBackup 7.1 minor release contains the features and fixes from 7.0.1
  • NetBackup 7.1.0.2 is a maintenance patch and contains the defects addressed in 7.1.0.1.

Symantec NetBackup has always maintained that the master server within your environment must be at a version level that is equal to or greater than the version levels of your media servers and client servers within the same environment. Beginning with NetBackup 7.1 and the NetBackup Appliances, you can apply a maintenance update (triple-dot release) to just a media server or client server within an environment where your master server is at a matching major, minor and release update level.  More information specific to maintenance compatibility can be found below.


Solution



It is recommended to have all NetBackup (NB) master, media, client, and database extensions on the same major, minor, or release update.  In larger environments it is not possible to update all servers and clients simultaneously. NetBackup therefore allows for servers to run a mixture of NetBackup major releases and release updates in the same environment. This capability gives rise to a number of general multi-version co-existence rules, together with some version-specific rules.
 
General rules for major, minor, and release update co-existence:
  • The statements made below do not override standard EOL policies.  Once a NetBackup version is EOL, no version of that product is Supported.  Please review the EOL technote for more information: www.symantec.com/docs/TECH74757
  • OpsCenter/OpsCenter Analytics must always be running the same or higher major, minor, release update or maintenance patch as the master servers in the environment.
  • In a mixed version configuration, master server must be running the highest major, minor or release update version of NetBackup in use in that configuration. 
  • NetBackup clients should not be running client software that is a newer major, minor or release update than the NetBackup master and media servers.  For example, a NetBackup 7.0 master server will not be able to properly back up or restore files to a client running the NetBackup 7.0.1 client software.  
  • Media and Client server backwards compatibility extends only one major release behind the master server.  A NetBackup 7.0 Master is compatible with 6.x media and client system, however, NetBackup 5.x and earlier systems are not compatible.
  • All components (master, media, client, console, and agent) on an individual system must be at the same version.
  • Backup images created under an older version of NetBackup will always be recoverable with a newer version of NetBackup
  • A new feature may not be functional until the master, media and client are updated.
  • Administration Consoles cannot be at an earlier version than the NetBackup server version they connect to via the "change server" functionality in the console


Rules specific to NetBackup maintenance updates:

  • Maintenance patches can be applied to the master, media, or client in any order to maintain compatibility
  • All OpsCenter components must be at the same patch level and a higher or equal level as the NetBackup master server
  • It is recommended for the customers using Bare Metal Restore (BMR) to have the highest maintenance patch level on all the three BMR components, that is master server, BMR boot server, and BMR clients. However, already supported BMR clients can run with a higher maintenance patch level than the master or BMR boot server.
    In case you are deploying a maintenance patch on BMR client/s to enable the disaster recovery protection for newly supported platform, then you may need to update the master server and BMR boot server as well with the same or higher maintenance patch version. This is required condition as the newly supported platform may contain changes at the master and BMR boot server side. Refer NetBackup Release Notes document for the maintenance patch release to get more information..
  • All components (master, media, client, console, and agents) on an individual system must be at the same maintenance patch
  • Certain defects may require fixes on the master, media, and client system to resolve the issue
 
Rules specific to NetBackup 7.5
  • A 7.5 master server is compatible with 6.5.X/6.0 media servers; clients connecting to the 6.5.X/6.0 media servers are compatible as long as they are at least version 6.0
  • OpsCenter Server should be at the same or higher level as the NetBackup Master being reported on
  • The NetBackup accelerator feature requires configured media servers to be at a NetBackup 7.5 version level
 
Rules specific to NetBackup 7.1
  • Vsphere 5 Support in 7.1.0.3 requires all components be upgraded to 7.1.0.3
  • A 7.1 master server is compatible with 6.5.X/6.0 media servers; clients connecting to the 6.5.X/6.0 media servers are compatible as long as they are at least version 6.0.
  • OpsCenter Server should be at the same or higher level as the NetBackup Master being reported on.
 
Rules specific to NetBackup 7.0
  • A 7.0 master server is compatible with 6.5.X/6.0 media servers; clients connecting to the 6.5.X/6.0 media servers are compatible as long as they are at least version 6.0.
  • OpsCenter Server should be at the same or higher level as the NetBackup Master being reported on.

Rules specific to NetBackup 6.5, NetBackup 6.5.X
  • A NetBackup 6.5 master server is not compatible with a NetBackup 6.0, 6.0 MP1, or 6.0 MP2 media server that has tape media configured. A change to correct this issue was made in the NetBackup 6.0 MP3 release and was carried forward to NetBackup 6.5. Therefore, 6.0 MP3 media servers or later is compatible with NetBackup 6.5 master servers.
  • If the EMM server is a separate server from the master, it must also run NetBackup 6.5.
  • 6.0, 5.0MP4 (or later) or 5.1 clients are compatible with a NetBackup 6.5 master server and media server; however, 4.5 clients are not compatible with NetBackup 6.5.  While compatible, NetBackup 5.x is no longer Supported and 5.x clients should be upgraded to a 6.x level.

Rules specific to NetBackup 6.0:
  • 5.x is no longer Supported as a released version, the details below are for reference only.
  • A 6.0 master is compatible with 5.1 and 5.0MP1 (or later) media servers.  NetBackup 5.0 Maintenance Pack 1 or later is the minimum required version for a 5.x Media server in a 6.0 environment. See TechNote 278153 for additional details. 
  • A Hot Catalog recovery of a NetBackup 5.x media server will require additional steps. See the 5.x Media Server Catalog Recovery section of the NetBackup 6.0 Troubleshooting Guide for additional information.
  • The EMM host and the master server must be running the same version of NetBackup. Always upgrade these machines first. Only then can media servers be upgraded and finally client machines.
  • It is not recommended to use a storage unit on a NetBackup 5.x media server for the Hot Catalog Backup.
  • NetBackup 6.0 master and media servers is compatible with NetBackup 5.1 and 5.0 MP1 or later clients. 4.5 clients are not compatible.
  • NetBackup 6.0 does is not compatible using NetBackup 4.5 media servers.  Any NetBackup 4.5 Media servers must be upgraded to a minimum of NetBackup 5.0 MP1.

Rules specific to NetBackup 5.1:
  • The End of Standard Support for NetBackup 5.1 was March 31st 2008 and the End of Support Life is December 1st 2008.
  • The volume database host, the global device database host, the vmd/DA host, and the master server must all be running the same version of NetBackup. Always upgrade these machines first. Only then can media servers be upgraded and finally client machines.
  • Only by installing NetBackup 5.1 on a master server can any media server be upgraded to NetBackup 5.1.
  • Only clients running NetBackup 4.5 or later are compatible when the master server is running NetBackup 5.1, regardless of the version of NetBackup installed on the media server.
