As far as i see in the restic documentation, when i backup a folder that was already backed up, restic may not check the contents of each and every file. Only those files whose meta-data (modification time, size, etc.) indicates that they were changed, are being checked for content changes.
Is there a way to force full content comparison of the folder being backed up (usually done by calculating file checksums)?
It is a little pedantic, but under some circumstances file meta-data may be deceiving.
