Setting up encryptionThere are some steps you must follow to set up encryption with theencryptkey=save option.1. Specify encryptkey=save in the options file.2. Back up at least one file with asnode=ProxyNodeName to create a localencryption key on each agent node in the multiple node environment.Follow these steps to set up encryption with the encryptkey=prompt option:1. Specify encryptkey=prompt in the options file.2. Ensure that users of the agent nodes in the multiple node environment areusing the same encryption key.Important:v If you change the encryption key, you must repeat the previous steps.v Use the same encryption key for all files backed up in the shared nodeenvironment.Scheduling with client-node proxy supportMultiple nodes can be used to perform backup operations using the scheduler. Bygranting proxy authority to the agent nodes, they will perform scheduled backupoperations on behalf of the target node. Each agent node must use the asnodenameoption within their schedule to perform multiple node backup for the agent node.The following examples show the administrative client-server commands using thescheduler on multiple nodes.1. The administrator registers all of the nodes to be used: (1) register nodeNODE-A, (2) register node NODE-B, (3) register node NODE-C.2. The administrator grants proxy authority to each agent node: (1) grantproxynode target=NODE-Z agent=NODE-A, (2) grant proxynode target=NODE-Zagent=NODE-B, (3) grant proxynode target=NODE-Z agent=NODE-C.3. The administrator defines the schedules: (1)define schedule standard proxy1description="NODE-A proxy schedule" action=incrementaloptions="-asnode=NODE-Z" objects=/Volumes/Xsan1 startdate=05/21/2005starttime=01:00, (2) define schedule standard proxy2 description="NODE-Bproxy schedule" action=incremental options="-asnode=NODE-Z"objects=/Volumes/Xsan2 startdate=05/21/2005 starttime=01:00, (3) defineschedule standard proxy3 description="NODE-C proxy schedule"action=incremental options="-asnode=NODE-Z" objects=/Volumes/Xsan3startdate=05/21/2005 starttime=01:00.Note: Place the asnode option in the schedule definition only. Do not place it inthe client options file, on the command line, or in any other location.For more information about the server scheduler commands, see IBM Tivoli StorageManager Administrator Command Reference.Start the schedules using the following client command: dsmc schedYou can also use the client acceptor daemon (dsmcad), with managedservices set toschedule in the systems options file.Note:134 IBM Tivoli Storage Manager for UNIX and Linux Backup-Archive Clients Version 6.1: Installation and User’s Guide
