Troubleshooting

Resolve Duplicacy Backup Disk Space Errors

A full destination or local cache can interrupt large backup and restore operations.

Quick answer:

A full destination or local cache can interrupt large backup and restore operations.

Steps for Windows

  1. Inspect free capacity on the source, target and temporary directories.
  2. Review the Web Edition temporary-directory settings.
  3. Move temporary data only using supported configuration controls.
  4. Retry with a small test after ensuring sufficient free space.

How to verify the result

The job completes without disk-space errors and a file restores.

Important limitation

Do not delete unknown backup chunks or configuration files manually.

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.
