Question: What are unpopular ideas about Time Machine in macOS?

Answer:

Here are some unpopular or controversial opinions / ideas about Time Machine that appear frequently in forums, support threads, and tech discussions (especially among more experienced or critical users), even though many people still consider it one of the better built-in backup systems:

Time Machine is unreliable and fragile in practice
Many long-term users claim it “works fine until it suddenly doesn’t,” with silent corruption, cryptic errors, backups marked as damaged for no reason, and failed deletions. Some say you only discover the backup is broken when you desperately need to restore.
It is overrated and people overestimate how good/safe it really is
The fancy starfield restore interface gets praised, but critics argue the actual reliability is mediocre compared to third-party tools (CCC, SuperDuper!, rsync, etc.). Some call relying only on Time Machine “self-sabotage” for important data.
You should not use Time Machine as your only/primary backup
A fairly strong minority view recommends turning it off entirely or using it only as a secondary tier. They prefer bootable clones (Carbon Copy Cloner / SuperDuper!) because Time Machine can be opaque, hard to verify, and worse at full-system disaster recovery in recent macOS versions.
Time Machine is basically broken after certain macOS updates (Sonoma, Sequoia, etc.)
Complaints spike after major releases — iCloud Drive sync blocking backups forever, failing initial backups on Apple Silicon, massive slowdowns since Catalina/APFS changes, encryption weirdness, and needing full wipes/recreates far too often.
The “set it and forget it” promise is misleading
Many users say you actually need to manually verify backups monthly, exclude folders carefully, babysit it during big macOS upgrades, and accept that it will occasionally demand hours/days to “repair” or restart from scratch.
Restoring from Time Machine often fails when you need it most
Multiple reports exist of people unable to recover critical files or systems despite “successful” recent backups — either the restore process hangs, permissions break everything, or older versions simply aren’t accessible/usable.
It’s not a real archival solution
An unpopular take among casual users: Time Machine aggressively purges old backups when space runs low and was never designed for long-term archiving. If you want to keep files from 5–10 years ago, it’s the wrong tool.

These views are definitely in the minority compared to the general “it’s great and easy” consensus, but they appear consistently across Reddit, MacRumors, Apple Discussions, Hacker News, and tech blogs — especially from power users, developers, and people who have been burned multiple times.
