# Can I choose the time or the file name of an automatic backup?

No. A backup runs when it is due, as soon as the app is open, so it does not wait for a set hour. The file name is fixed, for example privacynotes-backup-2026-11-11-0902-macbook.pnbackupz: the date and time first, so the files sort in order, then the name of the device that made it.

The device name keeps the files of two devices apart when they use the same folder. Each device deletes only the older copies it made itself, never the files of another device or your own files.
