Symptoms

After performing an upgrade or a site XML import, the space or global activity history is missing.

Cause

The Usage Tracking (Activity and Global Activity) plugin stores the previous entries in the <confluence-home>\index\plugin directory. The missing index folder could lead to the global activity not showing.

Workaround

The only way to recover the data is from a backup of the index directory prior to any deletion.

Perform the following steps:

1. Stop the Confluence instance
2. Copy the <confluence-home>\index\plugin directory from the backup directory
3. Place it back to the existing index directory
4. Restart Confluence instance
5. Re-build the content indexing via the Administration console
6. Check if the previous data are being restored

Resolution

Track USGTRK-33 for a more robust storage mechanism.
