From Apple’s basic Backup to your iDisk, through the first version of Time Machine in 2007, to Time Machine to APFS in Big Sur.
Most hard disks become increasingly likely to fail after 3 years. All Time Capsules are now in that zone, and should either be replaced or have their hard disks replaced.

Here’s what happens when a Time Machine backup, normally the first, slows to the point where it’s just never going to finish.
