I’ve noticed that whenever I close Scrivener for Windows, I get a little window that says “creating a backup”, with a little progress bar that takes maybe 10 seconds to complete. I’m not familiar with this behaviour from Scrivener for Mac. I just wanted to make sure that this is intentional and that I haven’t somehow triggered a setting that is creating needless duplicate backups.
Go to File > Options > Backup (icon in the far upper right).
Here you’ll be able to view and modify Scrivener’s backup settings – where, when, how, and how many. The default setting is to retain 5 backup files. I recommend changing that to 25, unless you’ve got some other bulletproof backup system in place.
I’ll spare you my usual lecture about having proper backups. All I’ll say is a Scrivener zipped backup is cheap insurance, and the easiest (by far) mechanism for recovering a Scrivener project, if you encounter some issue that would otherwise cause Scrivener data loss.
