delay for background job per five minutes

Now we need configure the background job per five minutes,the job should get material document data during time entry every five minutes .

For example,Back Ground Job Start at 10:05:00 , 10:10:00, 10:15:00 , then

i.     10:05 need to download 10:00:00 - 10:04:59

ii.     10:10 need to download 10:05:00 - 10:09:59

iii.     10:15 need to download 10:10:00 - 10:14:59

But I'm worried that if the job delay more than five minutes ,the next job will not run,then the material document data in this five minutes will be missed.

So I want to search better solutions to meet user's requirement as get material document data every five minutes.
