[ale] how do I make a virus proof nas?

[Ron Frazier (ALE)]

Hi all,

I'm considering making a mini nas to run backups on here at home.  It would probably have 2 - 4 TB of storage.  My router has 1 USB port, so I could just attach a HDD to that.  Or, I could get something like a Buffalo Link Station which holds two drives and attaches to the router.

The main concern I've always had about having backup media attached all the time is that, if a virus got into the machine, it could attack and wipe out the backup drive.

So, I need to know how to make a virus proof nas, such that at least one partition on the device is accessible only  to the backup software for write mode.  I don't care if everything can read the backup file, but I only want the backup software to be able to add new files, write to them, or delete them.

I need something that can run while Windows 7 is running and backup using the volume shadow copy service.  I also need it to be able to back up the ext4 Ubuntu partition on the PC's HDD, either by reading the native file system or by using a sector by sector approach.  This way, I can just let the backups run periodically on their own and not worry about malware affecting the backup.

Any help is appreciated.

Sincerely,

Ron
