Duplicacy filters reduce unnecessary upload volume, but a wrong rule can omit essential files.
Steps for Windows
- List required file types and directories first.
- Open the backup's Include/Exclude settings.
- Add rules cautiously and check their precedence in the edition-specific help.
- Run a small test and inspect the resulting revision file list.
How to verify the result
Required files appear in the revision and excluded disposable files do not.
Never rely on an untested wildcard exclusion for a production backup.
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.
