+#### Missing Data Segments

 To fix errors related to missing data or files:
 
 1. First run `borg check $REPO_URL`. This will first check the repository files and then one or more archives.
 2. If the first step reveals errors, you should make a local repo copy, unless the data is non-critical.
 3. Next run `borg check --repair $REPO_URL` to ask Borg to fix any errors.
 4. Finally run `borg create ...` to do a full backup run and add potentially missing data.

-1. First try to the local cache `borg delete --cache-only $REPO_URL`
-2. If the first step doesn't resolve the issue, try moving or removing the security folder in `~/.config/borg/security/$REPO_ID`. Where the `REPO_ID` can be found using `borg config $REPO_URL id`
