Sync by ssh, including only one type of files

rsync -uPhivaz --stats  --include='*/' --include='*.dat' --exclude='*'  user@server.org:/path/to/remote/dir/ /path/to/local/dir/

First include all subdirectories, then all \*.dat files, and then exclude all others

umount /home/user/dir1; umount /home/user/dir2;

rsync -havxHAWXS --numeric-ids --info=progress2 > ~/rsync.out 2> ~/rsync.err

-v : verbose, mention files

-x : stay on one file system

-H : preserve hard links (not included with -a)
