Issue

After using the out-of-the-box online backup feature to back up and restore AEM on a system, which uses FileDataStore, it displays the following errors [1] and [2]. These errors indicate missing files in the restored datastore.

Cause

Online backup currently does not back up the FileDataStore properly. It is a known product bug, fixed in the latest AEM 6.1 Oak cumulative fix pack 1.2.23. This bug will also be fixed in AEM6.3 and in the later AEM versions.

Currently, the bug is only fixed in a hotfix for AEM 6.1, not AEM 6.2.

Resolution

  • Back up the datastore separate from the crx-quickstart folder:
    1. Stop AEM.
    2. To point to a location outside the AEM installation directory, modify the path configured in the FileDataStore configuration under crx-quickstart/install.
    3. Move your crx-quickstart/repository/repository/datastore to the new location you have configured.
    4. Start AEM. 
    5. After running an online backup, use some other backup technology to back up the datastore folder. Incremental backup is acceptable as files are only added to the datastore. Remove the files only after running the Datastore Garbage Collection.
  • Or, if you are using AEM6.1, apply Oak 1.2.23 CFP. Continue to use the online backup feature.
