rsync -az remote_user@remote.com:/home/remote_folder/ /home/rsync/from_remote

“-e ssh” n'est plus nécessaire

rsync -avz -e ssh remote_user@remote.com:/home/remote_folder/ /home/rsync/from_remote

À noter la présence ou l'absence du slash '/' à la fin du répertoire source qui détermine si c'est le répertoire lui-même qui sera synchronisé (sans le /) ou bien son contenu (avec le /).

Si l'on veut passer des options à la commande ssh on ajoute des guillemets '“':

rsync -avz -e "ssh -i ~/.ssh/une_cle_privee" remote_user@remote.com:/home/remote_folder/ /home/rsync/from_remote

Quelques options pour la commande rsync:

    -v, --verbose increase verbosity (-v -vv -vvv)
    -q, --quiet decrease verbosity
    --progress show progress during transfer

    -n, --dry-run show what would have been transferred
    -z, --compress compress file data

    -a, --archive archive mode. It is a quick way of saying you want recursion and want to preserve everything.
    -r, --recursive recurse into directories
    -R, --relative use relative path names
    -t, --times preserve times
    -c, --checksum always checksum

    -u, --update update only (don't overwrite newer files)
    -W, --whole-file copy whole files, no incremental checks
    -I, --ignore-times Normally rsync will skip any files that are already the same length and have the same time-stamp. This option turns off this behavior.
    --size-only only use file size when determining if a file should be transferred
    --existing only update files that already exist

    --delete delete files that don't exist on the sending side
    --delete-after delete after transferring, not before
    --force force deletion of directories even if not empty

    --exclude=PATTERN exclude files matching PATTERN

    --daemon run as a rsync daemon
    --password-file=FILE get password from FILE
