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.
You must log in or register to comment.
Resilient filesystems/raid/multiple backup points should be more than enough.
A word of caution on relying on backups without the other types of error prevention you mention: If it takes you a while to notice that bitrot has ruined a file, then it may have already propagated through your backups. The only type of backups that would account for this is archival backups, such as on tape or quality bluray discs.
Yeah, that’s kind of what I expected and I am now thinking of keeping my setup how it is currently and getting a mini PC for less important data and services to tinker with.
