What is your definition of an incremental backup? I do not understand how bacula cannot restore data that was on your machine at the time of backup. As far as I can see that is exactly what it does.
A proper incremental backup should also track files that were removed since the previous backup. This is the only way that a system can be restored to the exact same state that it was in at the time of backup.
Also Bacula's incremental depends on files' timestamps, not their ctime, so files that get moved without having their timestamps manually updated won't get picked up during an incremental run.
These are common limitations of a lot of backup software. That doesn't necessarily make them excusable... whether they're significant deal-breaker issues depends on your environment and data. Bacula claims to have projects in progress to fix both of the above issues.
