High Availability Backup Procedure

You can use this procedure to reduce backup time ONLY for Exalead CloudView HA deployments where the slave hosts are simple duplicates of your master host.

Warning: Do not use this procedure if the slave hosts support the Storage Service role.

This task shows you how to:

Back Up Data on the Master Host

  1. Go to the <DATADIR>\bin directory.
  2. If your Exalead CloudView configuration uses a crawler, stop it using: 
    cvcommand <HOSTNAME>:<BASEPORT+11> /mami/crawl stopCrawl crawlerName=mycrawler
  3. Freeze all build groups with the cvcommand tool:
    1. Go to the <DATADIR>\bin directory.
    2. Freeze the services using the master freeze method. For example: 

      cvcommand <HOSTNAME>:<BASEPORT+11> /mami/master freeze

      Note: While in freeze mode, all push operations are suspended, no indexing jobs are created and trigger job conditions are ignored.

  4. Disable that processes using: 
    cvcommand <HOSTNAME>:<BASEPORT+11> /mami/indexing getBuildGroupStatus buildGroup=<BUILDGROUP>
  5. Define the following to enabled=”false”: PushServerStatus, AnalysisStatus, ImportStatus.
  6. Back up the <DATADIR> and the <INSTALLDIR>. To reduce disk copy time, do not copy the DATADIR>/run folder (containing logs).
  7. Unfreeze all build groups. For example: 
    cvcommand <HOSTNAME>:<BASEPORT+11> /mami/master unfreeze
  8. You can now restart your crawler if your Exalead CloudView configuration uses one. 
    cvcommand <HOSTNAME>:<BASEPORT+11> /mami/crawl startCrawl crawlerName=mycrawler

Back Up Data on the Slave Hosts

Context: On the slave hosts hosting the search servers:

Back up the <INSTALLDIR> if you applied patches. Saving the <INSTALLDIR> does not require freeze/unfreeze steps.
