It does not have to be a dedicated server, by from my experience, a Windows 2012/2016 Server, completely dedicated to Backup and Restore is best, and this could be virtual or physical.

do i have to connect backup san storage to san switch ?

If you want to utilize SAN Transport for faster backups - yes. But not compulsory.

do i have to install any other product of veeam on my server ? "i am plan to get veeam backup and replication"
thanks.

No, other than a vanilla patched Windows OS

Do you intend to use Veeam on its own or leverage the MSA2040's remote snap feature? If I remember correctly you can connect the two MSA2040's together using a 10Gb iSCSI DAC cable (no switch needed) and replicate LUN to LUN using that, it would be whole LUN replication that way though, but you could mount the remote snap on a separate server to pull off individual VMs.

Note that DAC cables are limited to about 7m, for greater distances you would need 10Gb SFPs and fibre cable.

Even if it's backup rather than replication You're probably still better off connecting a dedicated backup server to the SANs directly using DAC cables (FC or 10Gb iSCSI) rather than going through the switch, It's cheaper and just as fast.

You can also install Veeam on virtual machine and utilize hot-add transport mode. Then it is not necessary to have a separate physical host. But you need to think where you would like to store your backups? You cas use some NAS device and connect it to Veeam backup server. Also to comply with Veeam 3,2,1 rule you should have 3 copies of data, on two different media and one copy offsite. So I would suggest also to utilize replication functionality of Veeam B&R and replicate your data offsite. Or use tape libraries (physical or virtual) and keep tapes in secure location.

hello,
i will use a san storage for veeam backup .
do you recommended to use nas for backup instead of san ?
thanks.

SAN is OK but it needs to be different SAN - not the same where production VMs reside. As in such case you'll have single point of failure and in case of disaster you'll loose not only VMs but also backups.

What ever storage you have available, you may find your SAN storage expensive to store backups, compared to an inexpensive NAS.

Correct cheap storage for backups ideal

How do you do a DR restore if Veeam is on a VM? Of course if the NAS is WSS2012 you may install Veeam on that as it appears to work as opposed to not working on WSS 2008 R2.

Consider a catastrophic failure where your SAN goes tits-up and you need to do a DR restore, how will you start the virtualized Veeam server? It can be restored of course but you would have to install Veeam first which takes time.

You need to reinstall Veeam but if you have configuration backup in place while Veeam config can be restored within few clicks. You can also in addition make periodic full backups of Veeam VM keep them aside and use extract utility when necessary to extract whole Veeam server as well without need to have working Veeam VM in place.
