Dear rsync users,<br>
<br>
I want to backup my Documents directory and instead of copying
everything to my external disk I tried to use this command line to
create an incremental backup with rsync on my external disk:<br>
<br>
$cd /media/My\ Passport<br>
$rsync -a --delete --link-dest=../BackUp08.2009_Ubuntu/ /home/thomas2/Documents/ BackUp01.2010_Ubuntu/<br>
<br>
<br>
but I get the following output:<br>
<br>
<br>
rsync: chgrp "/media/My Passport/BackUp01.2010_Ubuntu/." failed: Operation not permitted (1)<br>
rsync: chgrp "/media/My Passport/BackUp01.2010_Ubuntu/Cealign-0.8-RBS.zip" failed: Operation not permitted (1)<br>
rsync: chgrp "/media/My Passport/BackUp01.2010_Ubuntu/Cytoscape_2_6_3_unix.sh" failed: Operation not permitted (1)<br>
rsync: chgrp "/media/My Passport/BackUp01.2010_Ubuntu/Dendroscope_unix_2_3.sh" failed: Operation not permitted (1)<br>
rsync: chgrp "/media/My Passport/BackUp01.2010_Ubuntu/NAMD_CVS_Linux-x86_64-CUDA.tar.gz" failed: Operation not permitted (1)<br>
rsync: chgrp "/media/My Passport/BackUp01.2010_Ubuntu/PfMDR1_AAA1.fasta" failed: Operation not permitted (1)<br>
......<br>
<br>
<br>
Moreover when I try to create hard links from an older backup in my external disk with the following command line:<br>
<br>
cp -al BackUp08.2009_Ubuntu/Reduce/reduce.3.13.080428.linuxi386 BackUp01.2010_Ubuntu/<br>
cp: cannot create link `BackUp01.2010_Ubuntu/reduce.3.13.080428.linuxi386': Operation not permitted<br>
<br>
I also tried to use sudo, even login as root with "sudo su" but didn't
make any difference. The permissions of my external disk are the
following and cannot add write privileges:<br>
<br>
drwxr-xr-x 22 thomas2 root 32768 2010-01-13 04:18 My Passport<br>
<br>
Is this normal? Any advice would be greatly appreciated.
