Audacity crashed, hours of work silenced

You can Store them in the cloud or back them up to the cloud.

But it’s pretty unwise to have a live project open in the cloud - remote far away storage like that can’t keep up with the real-time demands of audio recording and editing,

So if you do have a project archived or backed up in the cloud you really need to copy it back to on-board storage for working on it in Audacity.
