Unitrends Free – Review: Part 2

In Part 1 of this review, I walked through the deployment and initial configuration of the Unitrends Free backup appliance.

I’m now going to touch briefly on some of the other features of the product before summarising my thoughts.

Recovery

There’s no point taking backups if they don’t work, right? Well there are a few options available here. The first of them is a file level recovery. This mounts a VM’s backed up disks as file shares on the backup appliance. To test it, I created a couple of test VMs to backup and selected to restore from one.

A file level recovery “job” is started and a share is created using the backup job number.

It’s pretty easy to browse to the share and the required files could be recovered from there.

Another restore option is an Instant Recovery. This creates a new virtual machine from the stored backups for a VM. Again, I tried it out on my test VM. The first step is to select the backup that you want to restore from.

Next up are the recovery options. I’ve selected “Audit Mode”. This creates a virtual machine that runs from a disk image located on the backup appliance. The intention is that it allows you to test if a recovery is possible without putting the VM back in to your virtual datacenter. The VM in Audit Mode will have no network connectivity.

It took a few minutes to create and boot up but it worked. Note that the VM has no network connectivity.

And here is the VM that got created in vCenter during the restore:

Some minor issues

There were a couple of little annoyances that cropped up during my testing. They may already have been fixed and none of them are major. Firstly, when trying to configure SMTP settings, each time the configuration dialog is opened, a new email recipient row is added – even if that’s not what I opened it for. And you can’t close the window until you remove the row (or add an email address).

201504116_130456-CapturFiles

 

Quite a few of my VM backups failed several times to begin with so I checked to see if there were any software updates via the update feature. Lucky me, there were.

201504118_080444-CapturFiles

 

But after closing the dialog and reopening it, they were gone. I had to reboot the appliance to get them to show up again. After applying the updates my backups were more reliable (although one of my Active Directory servers still refused to backup).

Do you recall the NTP settings that I made when first configuring the appliance? If not, here’s a reminder:

201504115_220413-CapturFiles

I used my own, local NTP server. It’s open and reachable from the network that I installed the Unitrends appliance to. But, when I viewed the appliance options… not there.

201504116_130491-CapturFiles

 

I noticed this due to the discrepancy between the times that I thought I had configured backup jobs to run and the time that they were running. Fortunately, changing the options via this dialog worked.

The initial installation and configuration only allows you to specify a primary DNS server. Personally, I’d prefer it if I could specify a secondary DNS server at installation time. You can add one later though.

201504118_090424-CapturFiles

Finally, it’d be nice if the backup jobs could clean up after themselves. When there is a backup failure, vCenter gets littered with lots of messages like this:

201504118_080421-CapturFiles

 

It’s easy to fix manually of course, by annoying. I might see if I can schedule a vRO workflow to take care of it.

My Thoughts

It’s not perfect (what software ever is). Aside from the issues I had above, the only other thing that bothers me a little is the installer. It’s delivered as a single .EXE file that is 2.2Gb in size. The process, once the file is open, is fine but it can take a while to open a file that big. Possibly, given who is likely to use Unitrends Free, it might be the simplest option. It’s just not the quickest.

As far as features go, the important ones are there. VMs can be backed up and restored. Individual files on a VM can be easily recovered as well. If you have a small Virtual Infrastructure, the sizing limitations aren’t likely to be an issue. And if you get bigger, it’s not unreasonable to pay for more features and capabilities.

On the whole, kicking the tyres on Unitrends Free has been a pleasurable experience. It was fairly easy to setup and use without having to read the manual.

Unitrends Free – Review: Part 1

I was asked to give a new, free backup tool a quick road-test recently.

Unitrends have had an Enterprise version of their backup software for some time. And, as I’ve used it a bit in my lab with an NFR license in the past I was only too happy to give Unitrends Free a go.

Features

As a free edition, you expect a basic set of features. The goal of such offerings is normally to get you hooked, but wanting more.

Unitrends Free offers the following features:

  • Backup from VMware vSphere or Microsoft Hyper-V
  • Unlimited VMs and host CPU sockets supported
  • Instant VM recovery (allows you to run a VM directly from the backup files) – this feature also allows for recovery verification testing and use of backups for test and development purposes
  • Unlimited incremental backups (subject to storage space of course)
  • Free forum support

There are limits however. For instance, backups are scheduled daily. You can choose the time and you can choose the days but they’re once per day. Storage is space is also limited, up to 1TB of data is supported. These limitations position the product as ideal for PoCs, labs, smaller deployments (such as for small businesses) etc. For more features and dedicated support, of course there’s the Enterprise version.

Download

To download Unitrends Free, a simple registration form needs completing on the Unitrends site. The software is offered as a pre-built appliance (there’s one download for VMware and one for Hyper-V) only that is comprised of a single file. There are also users guides and release notes files available.

Installation

As you’d expect with a solution that’s based on a Virtual Appliance, there aren’t many steps involved in getting it deployed and running. In keeping with a growing number of products that provide some form of installer to deploy their solution, Unitrends Free is packaged in such a way as to make deployment straighforward. The supplied single executable (.EXE file) can be run from a Windows desktop or server as long as you can reach your virtual infrastructure from it.

1. Once the installer starts, you’re presented with a prompt for login credentials to vCenter or an ESXi server.

201504115_220400-CapturFiles

2. I pointed the installer at my vCenter server and was next asked to choose a host and a datastore and supply IP address details (note that it’s sensible to have a DNS entry created prior to deployment).

201504115_220475-CapturFiles

3. You’re given the option to create some storage for backups to reside on during deployment. It’s turned on by default but I upped the default 128Gb to something more sensible.

201504115_220411-CapturFiles

4. That’s it for now and deployment commences.

201504115_220412-CapturFiles

5. A quick check in vCenter reveals the created appliance.

201504115_220429-CapturFiles

That’s all that’s required to install the appliance. However, it does require some basic configuration before it can be used.

Initial Configuration

1. Clicking Finish in the installer fires up a web browser pointed at the new appliance where you’re greeted by a License Agreement.

201504115_220493-CapturFiles

2. You’re then greeted by a configuration wizard. The first stage is setting the date and time. I chose to use my local NTP server, although this later transpired to be an issue.

201504115_220413-CapturFiles

3. The second stage is setting the hostname (note that it’s set to VMware_CE_UEB on deployment) and password for the root account.

201504115_220477-CapturFiles

4. Finally, the SMTP configuration is required.

201504115_220490-CapturFiles

Once these configurations are saved, the appliance should be all set to go. Except we need to define what needs protecting and to setup some backup jobs.

Backup Protection

What use is a backup appliance without any backup jobs? When you first hit the appliance’s dashboard, there’s a popup displayed containing a couple of tasks that help you to get started. The first of these is registering a host (to protect).

201504116_120489-CapturFiles

Since we already know that I’m using vCenter, let’s protect that and all of its VMs by clicking on “Register a Host”.

201504116_120408-CapturFiles

The details required are fairly straightforward. As part of the process of adding the host, a quick inventory is performed. Now we’re ready to create a backup job.

This is accomplished either from the same popup or via the “jobs” option on the left of the dashboard.

201504116_120445-CapturFiles

Step 1 of creating a backup job is choosing what you’re going to backup. I selected my vCenter server and then excluded the Unitrends appliance – it’d be interesting to find out if it’s intelligent enough to do that by itself later.

Step 2 is defining the schedule etc. This is all fairly simple to accomplish. In theory, that’s my lab VMs protected.

Fast forward to Part 2 to find out how I got on with the backups and my thoughts on the solution as a whole.
