Since it’s kind of related, here’s my anecdote/data point on the bit rot topic: I did a 'btrfs scrub' (checksum) on my two 8 TB Samsung 870 QVO drives. One of them has been always on (10k hours), while the other hasn’t been powered on a single time in 9 months and once in 16 months.
No issues were found on either of them.
- modzu 1y agoif only i could trust btrfs scrub
- kassner 1y agoWhat can’t you? I’m curious, as I somewhat rely on it.
- diggan 1y agoHow much have been written to each of them across their lifetime?
- Prunkton 1y agovery little, about 25 TB written on the always-on one. The offline one just does diffs, so probably <12 TB. Both are kind of data dumps, which is outside their designed use case. That's why I included data integrity checks in my backup script before the actual rsync backup runs. But again no issues so far
