2 | # This helper script makes it easy to use a passwd or group file to map |
3 | # values in a LOCAL transfer. For instance, if you mount a backup that | |
4 | # does not have the same passwd setup as the local machine, you can do | |
5 | # a copy TO the backup area as follows and get the differing ID values | |
6 | # mapped just like a remote transfer TO the backed-up machine would do: | |
7 | # | |
8 | # rsync -av --usermap=`mapto /mnt/backup/etc/passwd` \ | |
9 | # --groupmap=`mapto /mnt/backup/etc/group` \ | |
10 | # /some/src/ /mnt/backup/some/dest/ | |
