I'm running a linux-based media server which I've been using rsync to backup to individual external USB hard drives based on content. For arguments sake, say I have a TV backup drive and a Movie backup drive. I've been using the following command to back up the TV drive:

sudo rsync --size-only -rltDvu --progress /rmedia/video/television/ /media/backup/television/

Now the TV backup drive is full and I want to start backing up to a new TV backup drive. How can I tell rsync to back up TV files that were created only after a certain date? IOW, I don't want to backup files that have already been backed up.

I'd suggest creating a new directory named /media/video/television2. That
will allow you to keep your same backup method. Also it will let you know
which backup contains which files based on the directory on the server.

It would be good to do the incremental backup which will only transfer the newly created files and the modified old ones.

As an example,

rsync `find . -name "*.pdf" -mtime -60` prasanta@anothermachine:/tmp/

The above command would look for files with modified date less than 60 days and then copy across to another machine. Hope this helps.

Thanks! Once I added an -R option to rsync this does exactly what I want.
