I had one 8TB hard drive to back up my stuff and rsync'ing that was easy. Now that my hoard has outgrown 8TB i bought another 8TB drive.
My question is, how can I tell rsync to only sync files to the second drive that are not on the first drive?
I tried creating a file list with
cd /q/backup; find -type f > /oldbackup.txt
which creates a file looking like
./a/Dir/file1 ./a/Dir/file2 ./b/elsewhere/thing ./... ...
and then use it like
rsync -rvu --delete --exclude-from=/oldbackup.txt /x/live/a /x/live/b /r/backup/
but rsync still copied all files, seemingly ignoring the exclude list.
How do I get this to work?
Also, am I correct in assuming, that even if it worked, it would leave a lot of empty directories on the new backup?
