For now my server doesn’t have very important data most of it are your “Linux isos” I can just download again and I’m thinking of starting to move my file and photos to the server but in afraid. What if I get a ransomwarei don’t realize and all my backups get encrypted too? Or if the backups are corrupted and my disks breaks? But also I’m afraid about cloud because I’ve seen some posts about people getting their google accounts closed without notice for breaking TOS (maybe they did something wrong maybe not).
It is impossible to fully eliminate the risk but with a decent backup system in place it is somewhat unlikely to lose all of your data.
The 321rule should be used as a baseline. Your local backup should be snapshotted and somewhat hardened against ransomware (pull backups instead of pushing them, do not mount the backup volume to other machines). Cold backups also help.
Can I construct scenarios in which I lose all my stuff? Sure. But in those, we are either in deep shit anyway (CME, some big astroid) or it is pretty unlikely (targeted hacking)
I’m too poor for a 321 lol
How much value does the data have for you?
If it’s of very low value, that it doesn’t even justify the costs of doing proper backups, then it’s not so important to worry about it either.
me too
My backups are tiered. Some stuff gets no backup at all, some gets even more than 3.And I tend to reuse HDDs that got replaced in my main machine due to size for my backups. Power consumption hardly matters when it only runs for a few minutes a day.
This. With a proper backup strategy, you are reducing the probability of a catastrophic sequence of events. It becomes P(some unlikely event) x P(some other unlikely event) x … Etc. for as many events you can think of and/or can afford to mitigate.
As you say, the risk will never be zero. And even the best-laid plans can fail - the Gitlab incident a few years back saw five layers of backups and disaster preparedness fail.
Really, all you can do is backup your data using standard methods, and TEST THE RESTORE before you need to rely on it!
