ok, what you need to do is edit teh file /etc/sudoers
Then, assuming you named you user user1, add the follwing line:

user1           ALL=(ALL)       ALL

Open in new window


You can add it under the line that reads

root           ALL=(ALL)       ALL

Open in new window


Hope that helps

Hello,

There is an excellent article on how to do this here:
https://www.digitalocean.com/community/tutorials/how-to-add-delete-and-grant-sudo-privileges-to-users-on-a-debian-vps

Basically you need to login as the root user (or with root permissions) and add the user to the sudo user list:

sudo visudo

please see link below for examples, as root you can provide required priv to run certain commands to certain users:

Normally it is better to use groups of which the allowed users are members of rather than add every user to the sudoers file.

But otherwise it is the same, just edit that file.

mac_g, manually changing the gid for a user is not recommended under any circumstances, please follow my instruction to provide su access to a user.

after you edited the sudoers file,
the backup user should run the command with sudo before it, or use su to move up to root level before executing the command.
