Does anyone know what happens or what I should expect if I restore all contents of
~/Library/Keychains from a Time Machine backup? I'm trying to assess the risks of doing this.
The reason I am asking is my iCloud keychain, which contains about 8 years of pretty important "Secure Notes", disappeared a few days ago. I believe the reason for it disappearing is that its local copy became corrupt (there is now a files at
keychain-2.db-corrupt and it was created around the time I noticed problems). I have tried restoring just the
~/Library/Keychains/[redacted_guid]/ folder, but that didn't fix the problem.
A reasonable next step is to restore the entire folder, which I hope has a working db and valid links to it. But I am afraid this will make things worse. Currently, my system is working fine. Using my user password, I can unlock my computer from a sleep and I can unlock the secure parts of System Preferences. I can see things going bad fast if I screw up my primary login keychain.
