Updated September 2026: in 2022 I complained that Time Machine offered no choice of daily, weekly or monthly backups, along with other frustrations. Apple has since added a frequency setting. I have rewritten it into a guide to configuring Time Machine well.
I keep backups of everything important on my MacBook, both in the cloud and with Time Machine. My frustration was the lack of control: once Time Machine was on, it backed up hourly with no option to choose a different schedule.
Can you change how often Time Machine backs up?
Yes, since macOS Ventura. In System Settings, open General, then Time Machine, then Options, and choose Backup Frequency: automatically every hour, daily, weekly or manually. Hourly gives the most protection; daily or weekly suits people who find hourly backups disruptive.
What else can you configure?
- Exclusions: skip large folders you do not need backed up, such as downloads or virtual machines.
- Battery: choose whether to back up on battery power.
- Multiple disks: add a second backup disk and Time Machine alternates between them.
- Network backups: back up to a NAS or another Mac over Wi-Fi.
How long does Time Machine keep backups?
Hourly backups for the past day, daily backups for the past month and weekly backups for previous months, until the disk is full. Then the oldest are removed. Use a disk at least twice the size of the data you back up.
Is Time Machine enough on its own?
No. It protects against mistakes and drive failure, but a disk in the same room is exposed to theft and damage. Add an offsite copy, in the cloud or a second disk kept elsewhere.
Which frequency should you choose?
Hourly if you work on important files all day, since it limits how much you can lose. Daily if backups slow your Mac or you mostly browse and read. Weekly or manual only for machines that change rarely. Whatever you choose, keep the backup disk connected often enough for it to actually run.
How do you restore a single file?
Open the folder where the file was, choose Browse Time Machine Backups from the menu bar icon, move back to a date when the file existed, select it and click Restore.
How do you check backups work?
Open Time Machine occasionally and restore a test file. The menu bar icon also shows the date of the last successful backup.
