Subject: Cache Driver - Backup Never Loaded The condition that checks to see
 if the backup driver input is valid was prefixing the input with "cache_".
 Since the valid driver values don't have this prefix, the condition was
 always returning FALSE and the backup drivers were never being loaded. I've
 removed the prefix in the condition and added a debug log message for when
 the backup driver is used.
