There is no feature to restart job in 7.0.1.. You have to write your own logic to restart your job.. You can use DSPrepareJob function in batch program..
I think you may find the checkpoint-restart feature in 7.1 or later version, e.g. 7.5. However, from my own experience, the tool does not seems better than do it yourself.
Anyway, goto your supporting consultant and ask for an evaluation.
