RE: Secure Backups

I've been seeing similar issues where I work. Unfortunately the
administrator responsible for it has not being doing things quite the
'proper' way.

I would use the rule of least privilege. If you make it a domain user, just
add it to a Backup group or something and give that group the appropriate
rights in the GPO to allow it to execute properly. Plus it will need some
NTFS permission on the appropriate directories/files. I think it will need
at least Write permission if it is going to be setting the Archive attribute
(differential backups).

It will depend on what you're using to do the backups, so some trial and
error may be required. Or checkout the release notes or something that may
tell you what permissions the backup account will require with your
particular software.

Regards,
Lee Clemens

Hello security world,

I'd like to establish a secure and reliable backup procedure. Currently, the
person whom had this responsibility has not been using standard procedures
throughout our network. Things I'm looking for include account type to use
(local or domain - admin or not), and what rights should this account have
in each server? I'm assuming that the account should hold enough admin
rights on each box to be able to run the job but I'm unsure if it should
hold complete administrator rights. 

Your comments and suggestions are greatly appreciated. 

With best regards,
 
Rolando Ruiz
