I should probably know this, but is there any reliable method for backing up recordings to keep them in the event of a hard drive failure? I realize we have the ability to transfer recordings to an external drive, but that is still a single point of failure. If the external drive fails, the recordings are gone. Is there anything that can be done to keep a copy of recordings to protect against that? My External HDD is getting old and I have some recordings that are 10+ years old that I don't want to lose.
