[Securiry] Backup product and Vulnerability

Recently a lot of vulnerability was found in Backup product.
such as Arcserve and Netbackup.

• Arcserve

• Backup Exec

Backup product have to use system privileged user for backup system files.
I think only backup (file copy process) have to use system privileged role, and other
process unnecessary to hold system privileged.

Backup vender Should design with secure default!
