copy methods

Hello, can you make a copy method that verifies the modified and new files from one backup to another and only copies those that changed and the new ones, but maintaining the structure of the folders, or updating the new structures if they change, something similar in incremental mode, but assuming the new folder structures??

Do you mean, if the source structure is changed, scan then the destination for existing files? Is it not easier to delete the existing backup and force a new full backup plus normal incrementals then?

That's what I do now, but it takes me a lot more time.

The only solution I see if to use the much maligned Mirror function.

I have a kinda similar question... If I initiated my first "full" copy with a copy /paste and setup my Cobian task to run incrementals, it does not work. it ignores the 3 days of new files.
Would that mean I have to run a Cobian reflector "Full Backup" overwriting what is there (930Gb worth) and then the incrementals will work..?

You can simulate a full backup if you don't want to run a real full backup.

I've run a "Dummy Task" if that is what you are referring to. I'll include the logfile if that would help.

There should be at least 3x files to copy from Fri Manual backup (Copy/Paste). So that is why I need to know if I have to rerun all my new tasks as full first. There are Tb of data from multiple sources, some 25km away running over wireless links..

A simulation doesn't backup anything. It just adds an entry in the history of the task.
