-* `autosave`: micro will save the buffer every 8 seconds automatically. Micro
- also will automatically save and quit when you exit without asking. Be
- careful when using this feature, because you might accidentally save a file,
- overwriting what was there before.
+* `backup`: micro will automatically keep backups of all open buffers. Backups
+ are stored in `~/.config/micro/backups` and are removed when the buffer is
+ closed cleanly. In the case of a system crash or a micro crash, the contents
+ of the buffer can be recovered automatically by opening the file that
+ was being edited before the crash, or manually by searching for the backup
+ in the backup directory. Backups are made in the background when a buffer is
+ modified and the latest backup is more than 8 seconds old, or when micro
+ detects a crash. It is highly recommended that you leave this feature enabled.
