It is enough for my use case, considering the likelihood of my SSD and the USB stick going kaboom in the span of a single month is next to zero; if only one of them does it, I can use the other to recover the data to a third medium.
Do keep in mind that if you’ve got a flood, fire, or something else happening to your pc, it will be lost. That’s why I’d recommend an off-site backup, or at least to somewhere else in the house than where the pc is.
The stick in question is off-site; it sees the PC once per month, then it gets back to the drawer in another room. And regardless of its fate, if I had a flood or fire affecting my PC, in the second store of a brick house, odds are that I’d have far more pressing matters than the data.
As long as your data isn’t super important that’s okay. But if it is, keep in mind that the chance of your USB stick failing when you try to read all the data off it after your SSD fails is fairly high. USB sticks do not do well with long reads or writes and tend to overheat and kill themselves. I’d strongly recommend picking up a hard drive to use as a third backup; a new 2TB drive is maybe $60, and a refurbished one half that.
It’s mostly fluff kept for sentimental value. Worst case scenario (complete data loss) would be annoying, but I can deal with it.
That’s one of the two things the 3-2-1 rule of thumb doesn’t address - depending on the value of the data, you need more backups, or the backup might be overkill. (The other is what you’re talking with smeg about, the reliability of each storage device in question.)
I do have an internal hard disk drive (coincidentally 2TB)*; theoretically I could store a third copy of the backup there, it’s just ~15GiB of data anyway. However:
HDDs tend to be a bit less reliable than flash memory. Specially given the stick and SSD are relatively new, but the HDD is a bit older
since the stick is powered ~once a month (as I check if the backup needs to be updated), and I do a diff of the most important bits of the data, bit rot is not an issue
those sticks tend to fail more from usage than from old age.
Any failure affecting my computer as a while would affect both the HDD and the SSD, so the odds of dependent failure are not negligible.
I tend to accumulate a lot of junk in my HDD (like 490GiB of anime and shit like this), since I use it for my home LAN
That makes the benefit of a potential new backup in the HDD fairly low, in comparison with the bother (i.e. labour and opportunity cost) of keeping yet another backup.
*I don’t recall how much I paid for it, but checking local hardware sites a new one would be 475 reals. Or roughly 75 euros… meh, if buying a new HDD might as well use it to increase my LAN.
Depends a lot on the quality of the stick. I have some that have worked well for years, and had others that failed after just a few writes. You’ll probably be fine, but probably isn’t good enough for a critical backup.
Yeah I’d definitely agree with not using them for critical backups. I think they’re generally fine as long as they’re never holding your only copy of something, but then I’d probably say that about every kind of drive…
I wouldn’t even say that. Flash drives are good as temporary storage for copying/sharing files, or for stuff you need on hand (like a Linux boot stick), but I’d never include them as part of a backup system.

Out of interest how high is “fairly high”? I don’t think I’ve ever had a USB flash drive fail!
