SAN backup for Vmware is 1 HBA card enough on ESX side and Media server (Verison 7.6.0.2)

[faiskhan]

Hi,

Please do let me know if i have 2 HBA on my ESX server is that enough For san based Backup if all things are virtualised.

I have gone thorugh the Guide Provided by Symantec For vmware but what i am looking for i am unbale to find. during planning phase if my master and media server is on Virtual and i require it to be SAN based backup.

If i only connect one Fibre cable from my ESX server to Media server would it be enough?4

Thanks

what is the backup host does it virtual or Phyiscal?

if your backup host is virtual you can not make the SAN backups.. and you need to go for hot-add method..

SAN backup requires to have the Physical backup host

have a look at

It is virtual like on vmware. Does hot-add would give me the same speed as of SAN backups

Thanks

definatly not as good as SAN... but you have make it without phyiscal server

Hot-add Transport

  You can think of hot-add transport as a special case of SAN transport where the backup host is also a virtual machine. Plus there is a bonus, it works for non-SAN data stores as well. The backup host VM accesses the VMDK objects of other VMs directly from the data store (similar to SAN transport). It can protect all VMs on datastores to which it has access.

Pros:

  No need for a physical backup host

  Does provide offhost backups for those VMs not collocated with VM backup host

  The most efficient backup method for NFS based data stores (e.g. NetApp or FileStore providing VM storage)

Cons:

  It does use ESX server resources where the VM backup host is deployed

  You cannot protect VMDK files larger than 1TB (a vADP limitation with hot-add)
