FAQs
There’s no fixed time period for how long Time Machine keeps your files; the length of time that files are retained depends on the storage capacity of the disk you’re using to create backups. The Time Machine app automatically deletes older backups to make space for new ones whenever the backup drive fills up.
All Time Machine backups are automatically stored in a Backups.backupdb folder. You can find this folder on your backup disk or network-attached storage that you selected when creating a Time Machine backup for the first time.
Time Machine maintains a series of incremental backups, each representing the state of your Mac at different points in time. When you delete a specific backup, you’re only removing a particular snapshot from the backup history. The remaining backups will remain intact, and you’ll still be able to browse and restore files for your entire system from your existing Time Machine backups.
