If it crashes while doing an incremental backup....

If it crashes while doing an incremental back up, can I just delete the increment that crashed and run it again?

For example if I have full back 1 plus increments 2, 3,4 and 5 and while doing increment 6 it crashes, can I just delete increment 6 and run another incremental back up (a new increment 6)?  If I delete the crashed 6th one will it know to start from where 5 left off?

Thanks
