I have a backup of the documents, pictures and videos folders on a large external USB drive which took many hours to create. – Hey, even cloud services can lose files, as I found out to my cost 😏
I now have new files and modified copies of others which I need to copy to the backup USB drive.
Is there a quicker way to update ("sync") the backup with the new and modified files in Windows 10 without select all
> copy to USB
then waiting hours for the PC to ask if I want to overwrite the modified duplicates once it has gone through the files?
Best Answer
you can try using
--ignore-existing
skip updating files that exist on receiver
With this option, preexisting destination files are renamed as each file is transferred or deleted. You can control where the backup file goes and what (if any) suffix gets appended using the --backup-dir and --suffix options
Excludes older files - if destination file exists and is the same date or newer than the source - don't bother to overwrite it.
