Yeah. I can do that for the things I watch all the time, but sometimes I need to pull up a chart I haven't been collecting for (or if for some reason I miss a day of data, etc.). That's when I need backfill. The option for it has to exist and work well.
It seems from the API release notes that you can get up to 6 months of data. If you request 1 min bars you get 1 day's worth per request. For five minute bars, you get 1 week of data per request. For each request you specify the end date for the requested data. By making multiple requests with appropriate end dates, you can have 6 months worth.
