Is bit rot really a threat that I should worry about? (midwest.social)

I have recently become interested in mini PCs, but one thing that is stopping me is a feeling that bit rot could cause me to lose data.

Is bit rot something to worry about when storing data for services such as Git, or Samba. I have another PC right now that is setup with btrfs raid1 and backups locally and to the cloud, however was thinking about downsizing for the benefit of size and power usage.

I know many people use the mini PCs such as ThinkCentres, Optiplex, EliteDesks and others, I am curious if I should be worried about losing data due to bit rot, or is bit rot a really rare occurrence?

Let's say I have backups with a year of retention, wouldn't it be possible that the data becomes corrupt and that it isn't noticed until after a year? for example archived data that I don't look at often but might need in the future.

Thanks for the reassurance. What I currently have is exactly that, RAID for the local data, and a spare drive that is mounted and unmount when data is backed up, and that is rsynced offsite to a cloud provider. I figured that my current setup was really reliable as I had slowly been researching and working on this over a few years.

I have a sort of itch to play with a mini PC, I guess it would be best not to hurt any of my important data by downgrading the setup, however this is a good time to really sort and figure out what I need and is important and what isn't as important and can be reobtained if something fails on the mini PC.
