I searched online, to no avail. Is there some way to recover the access timestamp of my file on BTRFS, before the access timestamp which appears currently? Using HDD (not SSD). Please let me know. Is this question better suited for superuser? I made no snapshots (willingly), using Fedora and the metadata change dates back some two weeks... In fact to be precise I'm interested in two timestamps ago, which happened in rapid succession.

No, none of Linux' native file-systems keep this kind of record (and for good reason). To get something of such granularity you'd have to enable a very garrulous and costly auditing scheme that you'd sacrifice a lot of disk-space and constant writes for ... but that won't fix the historical data question.
- 1Right, I'm not looking for an official record but maybe there is data corresponding to the previous timestamp, which was marked as available to reuse but hasn't been overwritten yet on the btrfs, and can therefore be recovered by analysing the filesystem. I'm inclined to think that even such metadata changes are not written in-place by btrfs.user324831– user3248312025-05-23 19:42:16 +00:00Commented May 23 at 19:42
