RSync / compare?
Quick question about rsync results - and comparing file structure/etc.
I am migrating about 2TB of data from one server to another. The rsync completed this morning - and when I go to the old server - and do a disk usage check on the old server/compare it to the new server - there's about a 2GB discrepancy.
There are literally thousands of files on the system... Is there any way to do an easy/effective comparison to see what is the cause of the discrepancy?

I haven't used those tags before with rsync (kind of an rsync noob).
So would the command go like:
rsync --size-only --list-only ssh root@xxx.xxx.x.xxx:/var/ww
?
It's giving me an error on that :)

Take the rsync command you had and add: --dry-run
What was your rsync command? Which had a bigger size? Did you use the -l option to force the copy of symlinks as links, otherwise, they may just expand the files.
You can find try finding the symlinks in each tree to see if they match

find -L /PATH/ -type l
Try this
-a archive mode
-v verbose
-H preserve hard links
-c checksum
--dry-run actions simulated
I got this from this forum, it just so happened I needed this recently.
rsync -avHc --dry-run ssh root@xxx.xxx.x.xxx:/var/www/ /newdir/-a archive mode
-v verbose
-H preserve hard links
-c checksum

rsync -avzhe ssh root@xxx.xxx.x.xxx:/var/ww
is the command I used.

The dry run command doesn't seem to really do much - except show me the entire list of files (which is odd - because I would've thought it ought be incremental...meaning...fi
