I wanted to perserve everything, so I just took my archiving rsync command and altered it to go to localhost:/media/RALLY2/ (name of flash drive). I am getting errors with changing the group owner. Huh?So I try to just use mkdir to create a directory on the flash drive. The directory has a group of root ???So I try a chgrp and get: [root@mine me]# chgrp me /media/RALLY2/Stuff chgrp: changing group of `/media/RALLY2/Stuff': Operation not permitted OK why can't I set the group to something other than root? ls -lstr /media/ total 4 4 drwxr-xr-x 3 me root 4096 May 30 16:28 RALLY2 and of course for /media: 8 drwxr-xr-x 3 root root 4096 May 30 16:18 mediaMost likely the device is formatted as FAT32, which has no concept of permissions.Reformat it, ignore the errors, or modify your rsync command to not preserveuid/gid.Unfortunately, I have to use it on Win systems as well...
You can't expect it to maintain ext3 file permissions in a FAT32 partition :D
you could use tar, but then the files are not available without untaring.you MIGHT be able to also use acl permissions and getfacl/setfacl to build a permissions file which you can use to reset the permissions and still have the files available as normal files on the flash drive.
