Rsync copy files if dont exist
I have a setup where I have two drives.
  • TV
  • TVbackup

For what ever reason, I have a lot of content on my TVbackup drive which isn't on my TV drive.
  1. I want to copy all the files across which are on TVbackup but are not currently on TV.
  2. If there is a file with the same name but a different size or date, I want to copy this across too, perhaps with a (1) after it, or something similar so it doesnt overwrite the existing file.

The end result is that the TV drive will end up having all of the files which are on the TVbackup drive as well as its own files.

My starting point is this:
Code:
rsync /media/tvbackup /media/tv

But how do I make it skip if the same file (size and date) already exists in the destination.

Not yet, im paranoid about deleting my data.

So, if I have my setup like this:

TV
  • File 1 (Newer)
  • File 4

TVbackup
  • File 1 (Older)
  • File 2
  • File 3

Then I run this command:
Quote:
rsync /media/tvbackup /media/tv
I should end up with this result on the TV drive:
  • File 1 (Newer)
  • File 2
  • File 3
  • File 4

How can I get it so if there is a file with the same name on the destination as on the source, but a different size or datemodified, then the source will still be moved to the destination but with a different filename, such as file(1) or file(new).

This is 2TB of my music, movies and documents so I'm a little paranoid.
