Hello Maaz,

Edit the /etc/sudoers using "visudo"

#visudo

Place and entry

marshall hostname= NOPASSWD: /bin/cp -R /home /home/marshal/homedirbackup

marshall hostname= NOPASSWD: /bin/cp -R /opt /home/marshal/optdirbackup

And save the entry. Now execute as

#sudo /bin/cp -R /home /home/marshal/homedirbackup
#/bin/cp -R /opt /home/marshal/optdirbackup
Now you can be able to copy all the entries of home and /opt directories

Note: Change the hostname to your hostname. The permissions of the copied file will be same as the original files.

Senthil Murugan

Hello Maaz,

For the previous reply the, owner of the copied file will be "root" only .To preserve the file permissions use "-p" option with the cp command

Actually there is a switch to cp that is even better for backup/archive jobs than -p:

-a or --archive (same as -dpR)

==================================
-d same as --no-dereference -- preserve=link
-p same as --preserve=mode,ownership,timestamps
-R, -r, --recursive
copy directories recursively
==================================

HTH,
Ross
