Time Machine backups have changed in
Catalina, and Apple warns users that all
backups made by, and converted for, 10.15
won’t work with previous versions of macOS,
even Mojave...
This is partly because, in Catalina, backups
contain three volumes instead of the single
boot volume: one for the writable Data
volume, another for the read–only System
volume unless you decide not to back that up,
and a third for Recovery, which is normally
invisible as it’s not mounted. In addition to
this, Catalina uses different methods to
determine what it should back up. These
include using snapshots when backing up anAPFS volume, with the option of using
macOS’s internal database of changes
made to the file system, on both APFS and
those still in older Mac Extended format.
Those are put in new database files in the
backup, which won’t work with older versions
of Time Machine.
To retain your existing backups unaltered,
before upgrading to macOS Catalina, make
good backups in case you need to revert to
them. Turn Time Machine off, and then
archive your existing backups. After the
upgrade is complete, turn Time Machine back
on, and make a new backup set, ideally to
a different volume or disk.
Preserving your old Time Machine
backups in Catalina
I’m preparing to upgrade to macOS Catalina, but gather it upgrades Time Machine backups
so they can’t be accessed from older versions of macOS. How can I prevent that?Before you make the leap to Catalina, make sure you turn off Time Machine to archive your existing backups.Image rights: Apple.TECH SUPPORT & TECHSPLANATIONS
