I must rewrite the group ID after transfer, because the destination gid
(special group), is neither the source (users) nor the invoking id
(root) and I see no option to rewrite it in rsync.
There is none, effectively.
If you are using ssh, what you can do is to:
- define a dedicated account for your backup at the destination with
a uid of 0 (ie: root) and a gid of the special group you want
- change you backup script:
- to use this account
- to use not -a but -rlptoD (ie: -a without -g)
Yes, that looks good.
I run a second command at present to chown and chgrp the results, your
suggestion might be faster.
If you are not using ssh, but a mount of your destination on the
source machine, look at the possible mount options and use -rlptoD

PS: Using "rsync -a $SRC/* $DEST" is unsafe:
- it will fail if $SRC contains a file whose name contains a space
- it may fail if you have a lot a files under $SRC:
Argument list too long
- will not copy dot files
Use instead: rsync -a $SRC/ $DEST
Thanks, I had already realised this and have amended my script
accordingly (not that I usually create filenames with spaces, but
someone else might).
Many thanks Francis,
Robert
