Surely many people encounter this error. This forum helps people a lot in answering their questions
It sounds like you are trying to configure Cobian Backup to run an incremental backup but are facing an issue where it continues to copy all files instead of just the new or modified ones. Here are a few things to check:
Verify Backup Type: Ensure that the backup task is correctly set to "Incremental" in the backup settings. You can check this in the "Task properties" under the "General" tab.
Archive Attributes: Cobian Backup uses file attributes (specifically the archive attribute) to track changes in files. Make sure the archive attribute is enabled on the files. You can do this by:
- Right-clicking on a file.
Choosing Properties.
Under the General tab, click Advanced, and check if the "File is ready for archiving" box is checked.
Full Backup: After a complete backup, make sure that Cobian Backup has cleared the archive attribute from the files. If not, it will treat all files as new during the next incremental backup. You can manually clear the archive attribute by right-clicking on the files and using the file properties, but Cobian should do this automatically.
Permissions: Make sure Cobian Backup has permission to modify file attributes. If it's running under a user account without sufficient privileges, it might fail to change these attributes.
If you've already checked these settings and the issue persists, restarting the program or reconfiguring the task from scratch might help. Let me know if you'd like more detailed steps for any of these checks!
