Uh no, it's not if you do it properly.

Personally I spend about 2-3 minutes doing this. It's called regular
backups of /etc and other key locations of configuration data. Pull a
copy prior to the compromise.

That's why, dundunDUNNNNN, he said "copy only data, not programs."
Backing up data, not programs, means the chances of you getting
anything malicious in there is extremely low. In fact I dare say
nonexistant

Backup data areas, not areas in the path? Just a thought.

Which is extremely hard to do on a compromised system where the basic
tools you rely on to detect such things have been modified to hide the
very things you're looking for.
