Yes, and is super easy.

I do like this: cron to run the backup and then rsync to https://www.rsync.net, then an after script that check it was run and post to my telegram the analysis.

That is.

Another good option is Restic, since snapshots let you go back in time. That is useful in case you accidentally delete/break something and you're not quite fast enough to restore from backup before the next cron runs.
