I am writing because I am seeking some guidance on connecting a spare external drive to my Linkstation via USB.
I am running a Buffalo LinkStation Pro Duo (2TB model LS-WTGL/R1-V3) with firmware version 3.07 in a RAID 1 mirrored configuration for redundancy so that I have approximately 1TB of effective disk capacity. One of the two USB ports on the Linkstation is being used for connectivity with a UPS unit, leaving one USB port available. I also have a spare Western Digital 1TB external drive (My Book Home Edition model WD10000H1CS-00) which I am considering connecting to the Linkstation via USB.
It appears that I can either attach the external drive for additional disk capacity or I can configure it to serve as an external backup for the data on the Linkstation.
Is this correct? If this is correct, then I'm a bit confused about how this would work with the RAID array that I've already established. Could you please clarify?
Do you have any recommendations or suggestions?

So, I've connected my Western Digital 1TB external drive to the Linkstation via USB. Since the 2TB Linkstation is in a RAID 1 configuration with only 1TB of effective capacity, my intent is to configure the Linkstation to periodically backup the entire Linkstation to the external drive. How do I do that?

Thanks for the response, PCPiranha!
I will need to format the external USB drive. While the RAID array in the Linkstation is XFS, I would prefer the external USB drive to be FAT or FAT32 so that it can be read easily on other systems. It is actually FAT right now (which is strange I think since I didn't think FAT could go up to 1TB -- perhaps I'm wrong). So, what do I need to know about the format of the external USB drive? Can I keep it as FAT (or perhaps FAT32) and use it as a "backup destination" for my RAID array in the Linkstation?

I just read some pertinent help notes in the admin web interface:
"To use a USB hard drive as your backup destination, its file system must be either FAT32, XFS, or EXT3. FAT32 has a maximum file size of 2GB. XFS or EXT3 is recommended for backup hard drives."
So, it sounds like FAT32 will work, but since it's not actually recommended, I have to ask, what are the cons/risks to using FAT32 instead of XFS or EXT3?

It seems I'm at an impasse and I need some guidance please.
I have tried twice to format the external USB drive to FAT32 but after the format is complete, the file format is indicated as FAT in the admin web interface.
On the Disk Management > Disk Format page, I selected the target to be the external USB drive, and I selected the file system to be FAT32. I then go through the confirmation process and eventually it completes the format. Then I checked the file format on the Disk Management > Drive Properties page, and on the System Status > Drive Properties page.
Lastly, I went through the above process TWICE just to make sure I wasn't being daft. Both times, the file format after formating the disk indicates FAT instead of FAT32.
So, what gives? Am I doing something stupid, or is this a bug? If it is a bug, is it a known bug? Is it fixed by a more recent firmware version?
Your assistance is appreciated!

Okay, I'm trying to configure the Linkstation to backup the internal RAID array to the external USB drive every week on Sunday at 5 AM, but I think I've run into another bug and I need some guidance please:
On the Disk Backup > Disk Backup page when attempting to create a new backup job, I am presented with a drop-down selection box for the Backup Operation Mode. Specifically, the options are:
Please note that the second option is repeated TWICE. What gives? Is this a known bug, and if so, was it addressed in a more recent firmware?
Lastly, having read the "HELP" on the page indicated, I'm still somewhat confused as to how to achieve my intent. I would like to configure the Linkstation to backup it's internal RAID array to the external USB drive in the most efficient way possible. Please correct me if I am wrong, but I would think that the most efficient way would be to take a full backup every week AND to take differential backups every day. How do I configure this? Do you have any other recommendations?
