Windows doesn't have a concept of local or network, only block or file.
so how they know network shared folder ?? is it because they use SMB protocol right ??
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.
-
the limitation comes when you choose network shared folder
-
To get what you want, you will have to use a DAS or a SAN. The only difference between DAS and SAN are the protocol you use to talk to the device. i.e. DAS = SATA or SCSI communciation, SAN = iSCSI or other block protocol.
*edited for clarity
-
ooooooh i'm very very sorry i confused between NAS and SAN
-
in this case i will content myself with DAS, because as far as i can see SAN is the most expensive one
-
great, now i understand
i made my decision, buy a DAS and connect it with my file server and i'm done

Well, that really depends. You don't have to do crazy expensive SAN. The Drobo 5n mentioned earlier might be perfect for this.
-
i think i will buy a RAID 1 DAS, what do you think ??
-
i want the cheapest option
-
the size of the business is very small, and the size of data i want to backup is about 500 GB
