How to save cracking progress?

[fefafefa]

Hello Hashcat users!

My problem is that I don't know how to safe the cracking progress
in order to continue it later.
I know you can pause the process and later you can continue but without
closing the program. I am trying to stop the cracking process, reboot the
machine and later continue with it without losing the time spend before.

I didn't find a parameter or anything to do that...
Is it possible?

Thanks for all!

P.D.: I am using oclHashcat-plus with bruteforce.
