Simple rsync command

Sync a directory to a remote host — no trailing slash on the source or you’ll miss a level:

rsync -aP /home/user/data user@192.168.1.100:/home/user/

Useful flags:

--delete    remove files on dest that no longer exist on src
--dry-run   preview without making changes
-a          archive mode (recursive, preserves permissions/timestamps)
-P          show progress + keep partial transfers
