I need files from an old server that ran a daily duplicity backup and was deactivated six months ago. The backup files are store in an Amazon S3 bucket and the last backup was made about six months ago. When I try to restore it using duplicity, It doesn't find any backup chain. My guess is that it cannot find any backup chains because the last signature date is very old, and it expects a relatively new one to exist. Using the -t argument doesn't solve the problem. Any ideas? Thanks for taking a time to help.
