Backup File Server to DAS
-
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.

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

windows built in backup
Then you are right back to square one - your backups will be limited to one day.
no, i will have daily version of my backups because windows backup can do this if the destination is a local HD
You MUST stop saying local or network. You are confusing yourself. The options are only block and file. Block is what you are calling "local" and file is what you are calling "remote" and Windows calls "shared."
If you need using terms that don't make sense, you will keep making bad decisions because you can't differentiate the technologies properly.

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
You stated that this was not true in the original post.

Did you read the article about understanding NAS and SAN that I linked for you?

No, you skipped my article. DAS, NAS and SAN have no price difference. Anyone telling you that they are different based on cost does not understand the terms and you should not talk to them about storage further. We are only talking about protocols here, that there is a cost difference makes no sense conceptually.

No, the Drobo 5D, a DAS unit, was mentioned. The Drobo 5N is a NAS and only a NAS. It is, in fact, the only pure NAS available on the sub $50K market. The only SMB NAS device made.

I don't think anyone agrees that that is a good idea, because you are unnecessarily exposing and limiting yourself. What is your reason for going that route?

They are all the same price. You would have to look at specific devices. Most DAS, SAN and NAS are the same units in this price range. So it is all in how you hook them up, primarily.
The cheapest option would be different backup software with a NAS for all of your devices to backup to, surely.

For one server or all of the servers?

of course one server, since i will use DAS,
