Backups don’t include everything. Here are details of those items excluded from Time Machine backups, and why they’re excluded.

A brief reference to excluding items from being backed up, from Spotlight indexing their contents, and for them to be copied up to iCloud Drive.
Consider the fidelity of backup copies, the speed of a backup method, and the risk of losing the contents of that backup. And test backups by restoring samples from them.
Preserve documents according to how much time or money would be needed to replace them. For work in progress, macOS versioning can be a great help.
Automatic Time Machine backups aren’t scheduled to run at precise times, but when it’s convenient. This explains how, and what to do if goes wrong.
Two different errors when backing up two different Macs, a recursive RTFD document, and APFS path length limits. But what’s this about FileProvider?
In the past, a second, cloned bootable volume on a separate disk was a great advantage. Cloning has become harder, and Recovery better. What should you do now?
Copies, clones and backups are three different things. Here their differences are explained with examples from APFS and modern macOS.
If apps control the Quality of Service, which sets how macOS allocates them to different processor cores in an M1 chip, how can we have any control?
Signs of an SSD going down may be confusing, but when random apps seem to freeze, be suspicious. Diagnosis and recovery are also covered.
