Rsync Tips

Be careful with trailing slashes with rsync. Always test behavior first. Excluded directories are relative to the second-to-last folder of the copy-from arg. Here I am copying the some folder. But in order to exclude folders directly beneath some, I must still reference some in the exclusion. Note the trailing slash at the remote location, which means the some folder is copied into /bk/ rather than replacing the contents of /bk with the contents of some.

rsync -av --delete --delete-excluded --exclude={"some/folder-A","some/folder-B"} /home/user/some remote-sys:/bk/
