-* `autosave`: micro will save the buffer every `n` seconds automatically
- (where `n` is the value of the option). 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. If the value of the option is `0` then micro will
- not autosave.
+* `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.
