-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Rsync has 4 options for this...
1) Write all files as the owner and group that rsync is running as. This is the default and the only possibility when not running as root since only root can create files as a different UID. 2) Copy the user name and group name. This is what you get when you are running as root and use --owner --group or --archive. This means if the 2 systems have the same user name but with different UIDs rsync will translate so that the files come out with the same user name and group name on both systems if possible. If the user name or group name doesn't exist on the target system then the file/dir is created with whatever UID or GID number regardless of whether it is in use by another user or not. 3) --numeric-ids copies both as the number. This is what you normally want for backups. This way you have the exact UID and GID stored on the backups regardless of what those numbers mean to the backup system. Just remember to use --numeric-ids when you restore. This is especially important if you have to restore from a live environment that has completely different UIDs and GIDs than your normal system. That environment would have no idea how to translate names from option #2 during a restore. 4) --fake-super. This writes files like option #1 but also stores what the owner and group name or numeric IDs should be in a user xattr. The same info about --numeric-ids applies. Root access not needed except during restore.
