Incremental backups
Duplicati performs a full backup initially. Afterwards, Duplicati updates the initial backup by adding the changed data only.
Processing similar data in How the backup process works explains. Please detail, if you see otherwise.
Duplicati is not:
- A file synchronization program.
Duplicati is a block based backup solution. Files are split up in small chunks of data (blocks), which are optionally encrypted and compressed before they are sent to the backup location. In backup location, Duplicati uploads not original files but files that contain blocks of original files and other necessary data that allows Duplicati to restore stored files to its original form by restoration process. This block based backup system allows features like file versioning and deduplication. If you need to be able to access your files directly from the backup location, you will need file synchronization software, not block based backup software like Duplicati.
Feature request seems unlikely (to me) as the backup process (see above) uses discrete backup times.
Enable, start and check running status of the duplicati service:
sudo systemctl enable duplicati.service
sudo systemctl daemon-reload
sudo systemctl start duplicati.service
sudo systemctl status duplicati.service
but what you might really mean is you’d rather get direct copies. That’s a totally different program.
It would also prevent most of the Features (please look). It’s the wrong direction for deduplication.
Dont createnmultiple files called volumes says more, with a comment from the interim maintainer:
Thank you. It has been a long effort by many, starting in 2008 for Duplicati and 2012 for Duplicati 2.
Major redesigns such as some of these suggest are very unlikely. Let’s get Duplicati 2 finished first.
