Redis tilbyr funksjoner for lagring av data i n\u00f8kkel\/verdi-format, utvidet med st\u00f8tte for strukturerte dataformater som lister, hasher og mengder, samt muligheten til \u00e5 kj\u00f8re server-side skripter p\u00e5 Lua.

To lagringsmoduser st\u00f8ttes: periodisk synkronisering av data til disk og vedlikehold av en logger for endringer p\u00e5 disk. I det andre tilfellet garanteres full bevaring av alle endringer.
