             Summary: Doc task: making/using backups when there are indexes
                 Key: GEODE-2985
                 URL: https://issues.apache.org/jira/browse/GEODE-2985
             Project: Geode
          Issue Type: Bug
          Components: docs
            Reporter: Karen Smoler Miller


We should document that making a backup or using a backup to restore a system when that system
also has/had indexes can be problematic.

When taking a backup on a system that has an index, if there are region operations in progress,
the asynchronous nature of propagating the results of the operations to an index means that
the index content may be inconsistent with the region content.  If the backup were later used
to restore a system, the inconsistency will be introduced back into the system.

The fix for this is to make sure that the system is quiescent with respect to region operations
when a backup is taken.

In addition, the restoration procedure should rebuild indexes.

This issue exists for both regular (OQL) indexes and for Lucene indexes.
