Site to Site Replication

Afternoon all,
      I have been tasked with replicating backup data for a client between two sites. The configuration is as follows:

Datacentre:
Qnap TS-879u-RP
Vmware vSphere 5.5
VDP1 - VDP 5.5
VDP2 – VDP 5.5

Remote office:
Qnap TS-879u-RP
Vmware ESXi 5.1

The VDP appliances at the datacentre are running to iSCSI Lun on the Qnap devices. I need to replicate the data from the VDP1 & VDP2 LUN to the Remote office (100Mb pipe). I am sure there are a number of ways to complete but I seems to be going around in circles.

~Option 1  - Qnap LUN backup & Restore (the smaller 1.6TB was estimated at over 110 hours
~Option 2 – Replication Job usine VDP (is the full version required here or can this replicate to a standalone VDN on the remote office ESXi server.
~Option 3 – 3rd party software solution to manage Lun replication


Any option or fleshing out of the above would be much appreciated.

buy an external 3TB usb3.0 hd from staples for $100

export to drive, then import from destination

1. SAN based replication is often quicker, and easier if available to you, I'm not familiar with Qnap replication, but we use NetApp Snapmirror, and Equallogic Replication and it works very well, because it Snapshots the LUN, and sync-s only the delta changes, after the first initial Sync.

2. Replication at the VM, level is what Veeam Backup and Replication, VMware vSphere Replica, VDP does. Standard version of VDP 5.5, is all that is required. VDP replicates the Backups in the Repo, not the VM, to another ESXi server. So you need to have a backup already of the VM. It does a good job and means, that you can be replicating and backup up VMs at the same time.

You can also create a SINGLE Replica Job, to send ALL your Backups to another ESXi server.

3. Third Party software at LUN level, not seen any really, other than SRM, if SRM has support for Qnap.

Thanks for the prompt responce,

can you please elaborate a little. Are you talking around the Qnap device?

add an external device/Drive then create a job to the external target will this allow me to backup the LUN?

Best Practices: Disaster Recovery Testing

Besides backup, any IT division should have a disaster recovery plan. You will find a few tips below relating to the development of such a plan and to what issues one should pay special attention in the course of backup planning.

What is the speed of your connection for replication?

Do you have at least a 1GBe link?

I would use VDP.

Hi Andy,
     

1, i cant see any Qnap replication option between the devices (hope i'm wrong as it would have been nice)

3. i am happy to disregard this option.

2.  VMware vSphere Replica - does this require vCentre at both sites,
2.  VDP i am looking into this but not too sure of the configuration i would require at the remote office site would this also need to be in the vCentre configuration .?

connection between the sites is 100mb p2p leased line. this would be available for approx 8 hours per evening for replication.

You just need to specify a Host at the DR Site....

Sorry for seeming a little special here...

Within the VDP1 > Select Replication Tab > New Job > Single Machine (for test) > esxi IP address > root details....

just sites there looking.. do i need to spin up a VDP at the remote office and point at that device in the above replication?>

The Host at the DR Site needs to be:-

so you will need an ESXi Server Hosting the following:-

1.  Avamar Virtual Edition (AVE) or Avamar Server), if you are using VDP.

if you are using VDP Advanced, you need to replicate to VDP Advanced.

I have been to this point before looking at the Avamar Virtual Edition. on trying to locate an ovf was just sent around in circles from both Avamar and the Vmware login.

Will this be a purchase to get close to a solution?

I am pushing Vmware and EMC to finalize the solution but i believe the VDP/AVE would be the best fit but can not confirm until implemented.
