Investigate storage connectivity, credentials, source paths and the job log before retrying.
Steps for Windows
- Open the most recent failed Backup job and read its log.
- Check destination availability and access credentials.
- Verify the selected source directory still exists and is readable.
- Run a small test backup and confirm a new revision.
How to verify the result
The test succeeds and the original error no longer appears.
Do not delete backup history simply to silence a failure message.
Why this matters
The practical goal is a recoverable Duplicacy revision, not just a successful-looking progress indicator. Keep your source, backup destination, Backup ID and necessary credentials documented. If this workflow changes your retention or storage configuration, verify a restore before applying it to important data.
