Using any browser comes with the same amount of risk, in fact.
But if the regular user cannot overwrite the backups - there's little
harm in that.

Cron can and will send a e-mail to a pre-determined address, if a batch
job writes something to stdout/stderr.

a) Log all and everything, and get your e-mail every day.
b) Log errors only and get your e-mail only if something goes wrong.
I prefer the latter, but YMMV.
