Scheduling backups with client-node proxy support

Multiple nodes can be used to perform backup operations using the scheduler.

About this task

When you grant proxy authority to the agent nodes, they perform scheduled backup operations on behalf of the target node. Each agent node must use the asnodename option within their schedule to perform multiple node backup for the agent node.

Start the schedules using dsmc sched client command:

The following examples show the administrative client-server commands using the scheduler on multiple nodes.

  • The administrator registers all of the nodes to be used by issuing the following commands:
    • register node NODE-A
    • register node NODE-B
    • register node NODE-C
  • The administrator grants proxy authority to each agent node using the following commands:
    • grant proxynode target=NODE-Z agent=NODE-A
    • grant proxynode target=NODE-Z agent=NODE-B
    • grant proxynode target=NODE-Z agent=NODE-C
  • Mac OS X operating systemsOracle Solaris operating systemsLinux operating systemsAIX operating systemsThe administrator defines the schedules using the following commands:
    • define schedule standard proxy1 description="NODE-A proxy schedule" action=incremental options="-asnode=NODE-Z" objects=/Volumes/Xsan1 startdate=05/21/2005 starttime=01:00
    • define schedule standard proxy2 description="NODE-B proxy schedule" action=incremental options="-asnode=NODE-Z" objects=/Volumes/Xsan2 startdate=05/21/2005 starttime=01:00
    • define schedule standard proxy3 description="NODE-C proxy schedule" action=incremental options="-asnode=NODE-Z" objects=/Volumes/Xsan3 startdate=05/21/2005 starttime=01:00
Note: Place the asnodename option in the schedule definition only. Do not place it in the client options file, on the command line, or in any other location.
You can also use the client acceptor daemon (dsmcad), with managedservices set to schedule in the systems options file.
Note:
  • Each schedule can be started from a different workstation or LPAR.
  • After running the schedules, any proxied client can query and restore all of the backed up data.
  • A proxy operation uses the settings for the target node (such as maxnummp and deduplication) and schedules that are defined on the IBM Spectrum Protect server. The IBM Spectrum Protect server node settings and schedules for the agent node are ignored.
