I was wondering how long rainwater can be saved and still be bennifical to water my herb garden during the dry spells.

Just about forever as the algae and stuff that might build up and contaminate the water is not harmful to the plants - not real good for you though!
However if your area has high air pollution (lots of smog alerts) it might contain heavy metals and acids which are not good for your plants. In that case if you can alternate tank water with town water, it might help reduce the stress to the plants.

The rainwater will still be good long after the barrels have rotted away!
If the mozzies are likely to be a problem, a couple of soup spoons of kerosine on the top of the water will stop them breeding. The larvae won't be able to breath through the kero and will die.

We only have rain water where we live and have to stow rain water to live. We have a 10,000 gal under ground tank, an 8000 gal plastic tank and two 1500 gal metal above ground tanks. The water in these is never empty and we have been here 12 years so I don't think there is any limit as long as the water is covered

You can save it until you need it. Keep your barrels covered to avoid mosquitoes. If they are not a problem, the algae that will form in the uncovered barrels is good fertilizer.
