But malware can overwrite users files which then get backed up..
implying you keep lots of backups.  For how long?

If I ever put debian on something I don't turn off then cron is an
option.  But right now I've got debian on a laptop that I don't leave
running 24x7

I prefer getting email every day - with a "no problems" subject line
if all goes right.  There's been times at work when something goes
wrong & part of the something was mail on the cron server.

I just tried running a cron job that fails (didn't chmod +x thescript).  No mail

Yeah.. I know.  Someday.  But setting up mail is way down on my
priority list somewhere after "install debian on a machine I'll leave
running 24x7" and I'm still working on "figure out how to dump
windows."
