I recommend a dead man’s switch like Healthchecks.io, which can be selfhosted for free. Whenever you have something that’s regularly occurring, add an extra callout to your unique Healthchecks callout UUID as part of the automation, and Healthchecks will send you a notification if something misses its callout schedule. You can also attach whatever data (e.g. a log) to the callout so you can look back through the run history. IIRC Borg will give you a non-zero return code if it detects problems, so you can send e.g. https://hc-ping.com/your-uuid-here/$? and a non-zero code will signal a notification as well (more examples here).
Also, Borgmatic is really easy to use for managing Borg repos. There’s a lot of configuration options (including Healthchecks.io integration) but you can delete like 90% of it for normal usecases.
There’s an unnerving lack of substance over on reddit. Recently I decided to look at reddit for the first time since last June, and every post’s comments had 1k people saying absolutely nothing worth reading. It feels like I’m reading AI-written posts that are in the uncanny valley of almost making sense and almost being on-topic. News articles have people that literally only talk about the exact words that were in the headline. Every single post’s top comments must be lame “jokes” or one-liners, and those must have several replies that riff off the joke in decreasingly-funny ways.
I’ve picked up a strong habit of immediately looking in comment sections for good discussion and TL;DR’s on Lemmy posts and it took me a while to realize that I wasn’t actually reading anything in reddit comment sections. The words pass through my brain and nothing of value is absorbed, over and over. It feels like low-hanging fruit to say “reddit is all bots now” but there’s something seriously wrong about how it feels over there. You only really need ~10-20 top-level replies on a post to get a broad spectrum of answers, and Lemmy comment sections feel solid for the content that’s here. I wish there were more communities here (especially niche ones), but I’m grateful for what we have.
