You need to be a little careful about configuration, but believe it or not, as long as Redis is configured with an append only file [1] it will provide you with a durability guarantee just like Postgres would. If it crashes, any jobs that were in there are recovered the next time it starts up.
From the docs:
> From now on, every time Redis receives a command that changes the dataset (e.g. SET) it will append it to the AOF. When you restart Redis it will re-play the AOF to rebuild the state.
