You can use backup reconciliation to synchronize the data on the source content and the index. For new subclients, backup reconciliation is enabled by default. For upgraded subclients, you must manually enable it.
When backup reconciliation is enabled, backup operations identify files that are missing from the subclient content on the source and the index, and then include the missing files in the backup.
If you cut and paste content in a file, the modified time of the file does not change. Because the modified time does not change, if you use the recursive scan method, the file is not backed up. However, when you perform a reconcile backup operation, the file is backed up.
If you enabled synthetic full backups for IntelliSnap at the CommCell level, then, for all subclients, after a synthetic full backup runs, a reconcile backup for the incremental backup automatically runs. However, if you selected the Reconcile Backup setting for a subclient and the backup copy runs after the snapshot backup with the catalog setting or the deferred catalog setting, then the reconcile backup does not automatically run. If you did not select the Reconcile Backup setting for a subclient, then the reconcile backup still runs automatically after every incremental backup that runs after a synthetic full backup.
Note
If a backup runs with the catalog setting or the deferred catalog setting, then the reconciliation is performed in the FileScan phase of the snapshot backup job and of the deferred catalog job. In this case, the same index for the backup copy is used instead of running the reconciliation on the backup copy.
