My BX750MI-GR has saved my precious data on two occasions. Earlier this year, my seven year old, well used waffle iron shorted, popping loudly and sparking quite brightly in the process, probably because of all the gunk that had accumulated inside its less cleanable interior over the years. That not only made my breaker trip, but also blew the 16 amp main fuse. The UPS kicked in immediately, making a klick and a beep, which felt amazing. That was my first time ever.
As for the second time, see this post.
Instructions unclear. May I interest you in some stories of the opposite subject?
So, I don’t have an UPS, but I have three short stories where my data was affected by its absence during a blackout.
First time,
btrfs zero-logcame in handy and nothing was lost. The SSD itself, however, was suddenly crashed just two weeks later.Second time my near-endgame Hollow Knight save file was irreversibly corrupted during the Zote dream fight, so I had to replay it from the beginning. Another of Zote’s dirty tricks for sure…
And the third time the entire FS was corrupted beyond all repairs. It was still capable to mount in read-only and was almost completely readable, apart from a few of cache files, but I still had to recreate the whole FS from scratch. Good thing I set up my backup just shortly before this incident!
By the way, I’ve been using Btrfs for 6-7 years, and have survived dozens of power outages, but so far only these three incidents have happened. So I take it as a success!
Did you ever find out what caused it to crash?
Reminds of when my smart ass didn’t check whether MiSide supports Steam’s cloud backups and I did a fresh install of my system. All my progress gone. GONE.
No, I have absolutely no idea. I’ve successfully received a refund for it, though!
