Administrator's Guide

Data That Can Be Exported and Imported

Administrators can export or import the following types of ADSM data:

• Server control information, which includes:
  • Administrator definitions
  • Client node definitions
  • Policy and scheduling definitions

• File data from server storage, which includes file space definitions and authorization rules. You can request that file data be exported in any of the following groupings of files:
  • Active and inactive versions of backed up files, archive copies of files, and space-managed files
  • Active versions of backed up files, archive copies of files, and space-managed files
  • Active and inactive versions of backed up files
  • Active versions of backed up files
  • Archive copies of files
  • Space-managed files

Attention: You can export information from an earlier version of ADSM to a later one, but not from a later version to an earlier.

Your decision on what information to export depends on why you are exporting that information:

• To copy information to a second server (the target server) to balance the work load across servers, use the EXPORT NODE, EXPORT POLICY, and EXPORT ADMIN commands. For example, when many client nodes access the same server, users contend for communication paths, server resources, and tape mounts during a restore or retrieve operation.

  To relieve a server of some work load and improve its performance, you may want to take one or all of the following actions:

  • Move a group of client nodes to a target server
  • Move policy definitions associated with these client nodes
  • Move administrator definitions for administrators who manage these client nodes

  When you complete the import to the target server, you can delete file spaces, client nodes, policy objects, scheduling objects and administrators from the source server to reduce contention for server resources.

• To copy data for the purpose of installing a new server, use the EXPORT SERVER command to copy all data to sequential media volumes.
