Answering Your Questions and Sharing Your
Tips About Getting the Most From Your MacDON’T USE CLOUD BACKUP
SERVICES TO MAKE COPIES
OF YOUR TIME MACHINE
VOLUMES. HERE’S WHY
Time Machine is a simple and generally
effective way to make an ongoing archive
of a Mac’s files and folder structure. But it’s
only a single copy of your data. The same
goes for third-party apps that can clone a
drive (make an exact duplicate) or makeincremental archives that let you retrieve a
snapshot of the current state of a volume
or older versions of files that have been
modified. These packages include Arq,
Carbon Copy Cloner, ChronoSync, and
SuperDuper!, as well as many others.
That single, on-site copy is a problem.
It’s why I’ve recommended for many years
that people also use a cloud-based
backup service that has robust encryption.
