Parece que você não quer que eles mudem após a transferência.
Experimente o comando abaixo:
rsync -avr -o -g /source/directory user@:destinationHost/destination/directory
Se você não usar essas opções, o usuário e o grupo serão alterados para o usuário solicitante no final do recebimento. Se você quiser especificar algum outro usuário, você precisará adicionar um comando chown ao seu script.
-o, --owner
This option causes rsync to set the owner of the destination file to be
the same as the source file, but only if the receiving rsync is being run
as the super-user (see also the --super and --fake-super options). Without
this option, the owner of new and/or transferred files are set to the invoking
user on the receiving side...
-g, --group
This option causes rsync to set the group of the destination file to be the same as
the source file. If the receiving program is not running as the super-user (or if
--no-super was specified), only groups that the invoking user on the receiving side
is a member of will be preserved. Without this option, the group is set to the default
group of the invoking user on the receiving side...
