This could be used for storage error tolerance or +caching of data in a faster storage driver. + +Configuration +============= + +An example: + +``` {.lua} +storage = "multi" +storage_multi_policy = "all" +storage_multi = { + "memory", + "internal", + "sql" +} +``` + +Here data would be first read from or written to [mod\_storage\_memory], +then internal storage, then SQL storage. For reads, the first successful +read will be used. For writes, it depends on the `storage_multi_policy` +option. If set to `"all"`, then all storage backends must report success +for the write to be considered successful. Other options are `"one"` and +`"majority"`.
