This may come as a surprise to you, but data is stored on storages.

Yes, on some physical storage devices with read-write access. No, you must specify each of them individually. WolfRecorder doesn't know on which you exactly want store your data. By default, after installation only “Default” storage is available. Its located in /wrstorage directory of root filesystem.

You can add as many “Storages” as you want. Only empty, writable directories on mounted file systems may be defined as “Storage path”

Like that
