As the title says, after smoothly running a Nextcloud server for 2 years and since version 13 with standard server-side encryption enabled since the beginning, last month I had the very bad idea to enable the master recovery key. I just now realized that files created prior to that date are not accessible anymore. Is there something I can do to recover user data?
Things I tried:
occ encryption:decrypt-all; it successfully decrypted recent files, but not those files encrypted before I enabled master key.
- I disabled master key from the interface and re-run
occ encryption:decrypt-all; this time it processed the old files, but after it completed successfully files still appeared to be encrypted. Very scary.
I know it’s my fault, no need to point it out. I just need to recover those files, any help would be greatly appreciated. Thanks.
