umask Question

I have a backup drive, and I only want the root account to have access to any files on the backup. The drive mount point is owned by root and has 700 permissions. How can I make sure that all files in the drive are also 700 permissions? I assume that 700 permissions on the drive mount point is sufficient to make sure only root can write to it. Isn't the answer somewhere in umask? I tried man umask, but didn't get any info.

Okay, I found a site where I read up on umask. If I were to put the following command:

umask 077

at the beginning of my backup script, would it then make all my backed-up files have 700 permissions, and then the umask effect would end after the script terminated? Just want to make sure it doesn't last longer than the shell it's used in.

Yes, it should work. After the script is done, if you log out and back in, or simply re-source /etc/profile your umask will be re-set back to what you always had.
