My problem is I learn some tool like this, set it, and then indeed forget it. Then I avoid testing my backups because of the work it takes to un-forget it. Because of this, I'm leaning more and more towards rsync or tools that have GUI frontends.

Rather than avoid tools that work well, I would encourage you to adopt solutions that solve your use cases. For instance, if you aren't getting notifications that a backup is running, completing or failing, then all you've set up is a backup job, and not built a BDR process. If you're looking for a tool to solve your entire BDR plan, then you're looking at a commercial solution that bakes in automating restore testing, so on and so forth.

Not considering all the aspects of a BDR process is what leads to this problem. Not the tool.

At a minimum you need backup, regular restore tests, and alerts when backups stop or restore tests fail.

Personally I automate restore testing with cron. I have a script that picks two random files from the filesystem: an old one (which should be in long term storage) and a new one (should be in the most recent backup run, more or less), and tries restoring them both and comparing md5sums to the live file. I like this for two reasons: 1. it's easy to alert when a cronjob fails, and 2. I always have a handy working snippet for restoring from backups when I inevitably forget how to use the tooling.

IMO alerting is the trickiest part of the whole setup. I've never really gotten that down on my own.

I recently set up email alerting through the syslog agent from Telegraf-Influx-Grafana, where Grafana is used for Email alerting and InfluxDB for filtering for the specific syslogs.

On another VM, I used postfix to email logs after cronjob (failed or passed), which also works great.

I use ntfy.sh for sending push notifications from scripts and such. It's open source and free (they have paid plans as well now, but I didn't encounter any limitations in the free plan).

Not an endorsement, just a happy user.
