You need multiple backups and versions of all your projects!! I've had projects get corrupted in
properly licensed versions of daws.
Truth: This does not happen very often when your stuff is properly paid for. But it does happen. And I can count on 1 hand the amount of times its happened to me..
Actually this very thing happened to me a few weeks ago, with something I was doing in Renoise... "save number 24," or whatever, didn't open.. Something had totally gone bonkers with that particular file... I had to go back to, "save number 23."
You've got to save. You need a system for saving. Learn the automatic back up features, have a proper file system for versioning...
Do you think I trust my hard disk, or do you think at this point I've got accounts at icloud, 4share, box, etc, etc.. I'm not going to name all the clouds I'm using, but you can believe I've got enough free acounts to cover several gigabytes of backups...
