Troubleshooting the Storer

The .str files are not being stored in the Inventory database
The Storer running on a Windows Inventory server randomly stops updating the scan data in the Inventory database
The CPU utilization of the Inventory server is 100% when the Storer is active
How do I back up the .str file?
How do I change to another Inventory database after the scan data has been stored in the Inventory database?
The Storer takes too much time to store the .str files
