VizionCore vReplicator VS Veeam Backup & Replication Introduction:

If you have reached this page you are more probably considering building a disaster recovery for your current Virtual infrastructure, but still can't solve the puzzle of the solution or the vendor to use you are at the right place. You might as well be thinking of building a new Disaster Recovery setup with a lower cost & found virtualization to be the solution for your problem. In this comparison, we will compare two third party products which depend on software replication to build a Disaster Recovery for VMware Infrastructure. In this comparison we will compare the two famous replication products VizionCore vReplicator & Veeam Backup & Replication which is designed to build a DR for VMware VI3 & vSphere.We will cover other solutions in the future including ones which depend on storage replication. This comparison was based on VizionCore vReplicator V2.5.4.0 & Veeam Backup & Replication V3.1.1.295.

VizionCore vs Veeam

We had created a 40GB Virtual machine & then cloned it. Then we installed Veeam Backup & Replication as well VizionCore Vreplicator on two different VMs with exactly same specs. We had started the replication at the same time of the two 40 GB VMs and was surprised with the result. The initial replication took around 2 hours using Veeam & around 4 hours using VizionCore vReplicator. Although Vizioncore took twice the time to do the initial replication, it was a lot faster on subsequent replications. It took Vizioncore around 3 minutes for each subsequent update where it took Veeam around 10 minutes for each subsequent update.

It seems Veeam is twice as fast at the initial replication, where Vizioncore is four times as fast on subsequent replications. It seems Vizioncore snapshot technology had succeeded to keep subsequent updates super fast, but that come at certain limitations with snapshots & so on you can find more about it in the rest of the comparison.

VizionCore vs Veeam

Both VizionCore vReplicator & Veeam Backup & Replication had started to offer vSphere support.

 

Neither Veeam Backup & Replicaiton nor VizionCore vReplicator support VMware ESXi as a backup target or a replica destination. Though veeam support ESXi as a source, which can help enviornments that must run ESXi on source, but not on their target (DR Site). We were not able to get a commitment of either vendor on when ESXi will be fully supported.

 

Both products don't work correctly with Thin provisioned disks, they can replicate thin provisioned disk, but the target disk will be converted to a thick disk.

VizionCore vs Veeam

Although both support VSS backup, its worth mentioning Veeam backup & Replication had master it way earlier than Vizioncore vReplicator, as well in our test environment the failover of a windows 2008 AD with vReplicator required us to go to AD Restore mode and fix it from there, where we did not have the same problem in Veeam. This is seems to be a known problem with vReplicator & hope to get contacted by VizionCore staff if there is away to avoid it.

esxReplicator vs Veeam

Although neither of the products support automatic failover, our team believe its never a good practice to use automatic failover for a Disaster Recovery. It is always better to control the DR failover manually and have a procedure on when to call for a disaster failover.

vReplicator vs Veeam Backup

Veeam backup & replication support a great feature which can enhance its speed and lower the affect on the host by integrating with VCB for replication.

VizionCore vReplicator does not provide any VCB integration for replication, although vRanger supported it for backup.

File level restore from replica

Veeam Replication vs VisionCore

This is feature has surprised our team to be included in a disaster recovery replication solution. I mean it really took a deep though to come up with that you might only require some files to recover your original site instead of failing the whole site. Being able to obtain that from your DR incase of backup failure or not available is not a bad idea. VizionCore vReplicator still does not offer this, but Veeam has been offering it for a while. Though this feature is included VizionCore vRanger  which is sold as a separate license.

Replica rollback

               NO

                 Yes

ITComparison Team Comments

Veeam vs VizionCore

If one feature that would really make a difference then this one must be the feature. As this will even protect you against major virus attack & data corruption in the main site. If you can't roll back to an earlier copy of your replication then if your last replica is corrupt you are out of luck. I believe Vizioncore should take a note of this feature and support it in future release. Another thumb up for Veeam.

Integrated Backup Solution.

               NO

             Yes

ITComparison Team Comments Veeam integrate both the backup solution & the replication solution into one product Veeam backup & Replication, where VizionCore sell the backup solution as a separate product called vRanger at an additional cost.

VisionCore vs Veeam

As both vendors have taken a different approach to their licensing schema, your mileage with their pricing will vary. If you are planning to replicate all your VMs & have many VMs per host then Veeam will definitely be a cheaper option. Though if you have many VMs, but only few need to be replicated & they are scattered across many ESX Servers then Vizioncore vReplicator might end up to be cheaper option.

- One thing to consider as well, Veeam price include their backup software, where VizionCore vRanger will cost an additional $500 per processor. Its some extra cost to consider if you are looking for a backup solution as well as a replication solution.

- It seems the current pricing model is hurting VizionCore vReplicator share of the market, as we had received an e-mail from VizionCore informing us that vReplicator will change its pricing model with the release of vReplicator 3.0 in Q4 of 2009 to be ~$500 per Socket, but till then it will still be priced at ~$500 per VM.

SnapShot support              NO                  Yes
ITComparison Team Comments While doing our testing we had noticed that we could not replicate Virtual Machines which have snapshots using vReplicator while it went without problems with Veeam. Searching that we had discovered the method vReplicator is using snapshot to get their blazing speed is the reason behind this.

Veeam Replication vs VizionCore esxReplicator

Again it seems Vizioncore snapshoting mechanism does not allow them to run backup while replicating. Even when using their vRanger backup software they had to implement a mechanism for the two products to communicate so no replication take place while backup is taking place. If you decide you want to use another product or just VCB to backup while protected by vReplicator you are out of luck. I guess another cost for the blazing fast replication.

As Veeam have their replication setup differently, they don't seems affected by this problem, as we were able to backup the same VM with VCB without having to shut its replication. 

Secure Replication             Yes                 NO

Veeam Replication vs VizionCore esxReplicator

VizionCore transfer its data over ssh, which secure its data transfer. If you don't trust the media your transferring the data across then this might get to be an important feature for you.

Veeam has a different thought & don't try to do the same. As securing the data while transferring forbid accelerating devices from accelerating the frames.

So it depend on your need of securing the transferred data or being able to accelerate your transfer on which method is better.

Veeam backup & Replication vs VizionCore vReplicator Blog Post:

   

We have done our best in comparing the two products & tried to keep it real as much as possible. In addition, we are opening a space to everyone to share their thoughts & let us know of anything we had missed in our comparison by opening a post at our blog where people can comment back with their thoughts. We welcome everyone thoughts even both vendors, as long they can stand behind it and prove it. We have our own lab setups, where we will validate every contribution.
