Backup File Server to DAS

Don't go for Drobo! They apply mods to Linux so you'll have hard times recovering data back from their devices. Been there done that (c) ...
Modify Linux? They don't even run Linux!

DAS also means if you get something like cryptolocker on the fileserver then it will likely mess with your daily backups. I hope you have off site backups too.
And to be clear, by DAS here he means all block devices as I mentioned above. Anything that appears to the system as a local disk is 100% vulnerable to ransomware like cryptolocker. There is a reason that local, always attached disks are not used for backup devices generally.
NAS will protect you from this as there is a ton more security and protection.
NAS will protect you from this only if the NAS isn't mapped. Most ransomware will walk standard shares today too.
So if your NAS has to be mapped into the OS before the backup software can run, hopefully you can create a script to map/unmap it as needed. -
hhhh i can see many choices and suggestion here,
what i want is only to make sure whether my windows server 2008 R2 will consider DAS as local partition so that i can make daily schedule backup (not overwrite the previous backup version but rather append the changes and keep daily version backups) -

Have you considered not using the built in Windows backup but instead using something for free? I'm not 100% sure on the features or limitations to Crashplan but I know that they are completely free and do some really cool stuff. And since they are free you could download it and test it all that you want. If it isn't better than the Windows Backup you could just switch back, no money lost.

They list local drives (external hard drive) as a backup option.
windows backup also offer these option (local and external HD) but for the external HD they don't keep old version backup but rather they overwrite each time the previous backups
for this reason i want an external HD but still considered by windows as local -

Yup, and that is answered. Without question, Windows has no means to determine if it is local or not local. It's block that you are asking about, not local. Windows doesn't have a concept of local or network, only block or file.

That's why he recommended a free alternative. Any reason that you are only looking to use Windows' limited backup options?

so how they know network shared folder ?? is it because they use SMB protocol right ??

Correct, Scott listed the two types above. Block and Network

oh great
what a about NAS ? is it considered local or network ?? -

Yes, the tip here is "shared." DAS, SAN, local disks are not shared - those are block protocols. NFS, SMB, FTP are shared - they are file protocols.

DAS and SAN are block. NAS and File Servers are file. Understanding NAS and SAN.
-
To get what you want, the ability to use Windows built in backup utility to get multiple days worth of backups, you have to use a block level protocol, which Scott already listed DAS, SAN or internal disks.
But the rest of us were warning you of the potential issues with regards to ransomware viruii that can easily damage those volumes since they are constantly online and accessible to the server in question.

thank you guys very much, now i'm ready to go
since i can acheive my goal with NAS, i will change my mind to buy a NAS, maybe i will need to backup other stuff on my network, since it is shared in the network
i will not buy DAS anymore cuz it is limited to one machine -

windows built in backup

Then you are right back to square one - your backups will be limited to one day.

i have been using it for a long time, i think it is great
the only limitation that i had is how to keep my backup externally
now that i will buy a NAS, this problem will be solved

no, i will have daily version of my backups because windows backup can do this if the destination is a local HD
-
But a NAS is NOT considered local. NAS uses file protocol, so it will not work for your needs.
