Large first backups need enough target capacity and a connection that stays available.
Steps for Windows
- Estimate the source size and available destination space.
- Exclude only known temporary data, after checking filters.
- Run the first backup when the PC can remain powered on.
- Watch completion, logs and restore one representative large file.
How to verify the result
The job completes and a large restored sample matches its source.
Cloud bandwidth limits and provider costs can dominate the initial run.
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.
