I do. And since I’ve been slowly taking back control over all my online stuff as much as I can, I’m very happy with it. It gives me peace of mind it’s secure and I am super unlikely to just lose it.
I use backblaze on my synology. I backup photos automatically to it with their built in app on my phone, then every night I run encryped backups. I also could setup an encrypted backup to go to my parent’s synology.
My backup is about 900gb and costs <$5/mo. That is my music, pictures, movies, and TV shows. Obviously that will increase, but well worth the nominal coat to have that much backup encrypted and in the cloud.
I had a heat pump and you could barely hear it outside. I had to be within 10ft to hear it running. It could be an age thing too. Mine was installed within the past 3 years, so that probably helps too.
