Only you can answer that. Ask yourself what you can afford to lose.

Hardly surprising if you're doing it with tar, which is making a
complete copy every time. That's the wrong approach. As I mentioned
earlier, rsnapshot, obnam and others can do incremental backups which
take up little space. They are also better run as cron jobs, i.e.
automatically. I run mine when my system is quiescent (4am every day)
but again that's your call.

And it goes without saying that the backup should be to another machine,
e.g. using rsync or a net-mounted filesystem.

Note that these are recommendations for a personal system that you can't
afford to lose. For larger systems you might want to look at solutions
such as Amanda or Bacula (not that these won't work on a personal system
as well, they just need a bit more setting up).

I can second that.

We're using rsnapshot for over 100 systems, combined with the traditional method that came from the days that people were still using tapes: daily (incremental), weekly(full), monthly (full).

And if you are worried about size, we do only the changeable stuff. (/home, /etc, /srv)
Anything else we regard as waste-of-time, as systems (iron&virtual) are installed automatically from templates in less than a few minutes.
