I am running a UEB VM appliance for one of my customers backing up a small number of VMWare VMs. Last night, at around 4am, something went sideways and I received a system failure report. The web interface is not accessible (communication error when attempting to log in). After SSHing into the appliance, I found an XFS error being thrown every few seconds (xfs_log_force : error 5 returned). The XFS volume behind the /backups directory was not mounted and could not be mounted.
Thanks for those details. Our support team thinks that you need to work with them because of one of the error codes that you reported. Your license includes email and chat access to our team, so please email them at sup...@unitrends.com. to get the quickest resolution.
In general, this is a very troubling situation - the UEB appliance is completely inoperable and will have to be re-imaged and all the backup data on it is lost. There is no discernible explanation of what triggered the corruption of the XFS filesystem.
- The error message is the same
- I was archiving a set of backups at the time of the crash - one backup was about 295GB, the rest were small - to a USB drive, similar to the large file transfer mentioned in the post
- I believe the XFS filesystem is created when the appliance is created and it starts relatively small (100-200GB) and I then added 2TB of additional storage, so it grew from a smallish filesystem to a larger filesystem, as noted in the above post
We already mentioned one of its most unique features, which its ability to support over a 100 versions of Operating Systems and Applications. Other useful properties of Unitrends Enterprise Backup has includes instant and granular spin-up recovery. Additionally, dissimilar physical and virtual bare metal allows users to perform P2P, V2P, P2V, and V2V recovery. Backups can be performed by users as often as once every 60 seconds. Also featured is Incremental Forever, which will improve recovery point objectives. Users can achieve smaller backup windows and improved network bandwidth efficiency using Near-CDP with up to 10,000 snapshots per week.
When first logging into the system the activity screen shows a historical view of all past activity, with a calendar heat-map ranging from green to red to indicate successful backups or problems to address. To perform daily tasks such as kicking off backups of new systems or maintaining the scheduling of different systems in the process of getting incremental backups, the process takes only a few clicks.
Once the desired server or VM is selected and the appropriate version, the next step is selecting the local server to restore it to. In our case we brought the off-site server into our main enterprise test lab and connected it to our ESXi cluster with available datastores to mount the VMs on.
After that click restore and wait for the backup to be rehydrated and placed in your environment. For mission critical systems, Instant Recovery is also an option to spin up the VM immediately and Storage vMotion it from the replication site storage on the UEB to a selected production datastore.
The Unitrends Enterprise Backup solution is about as easy as it gets when it comes to deploying enterprise-grade backup solutions. Once you figure out how and why the interface is laid out the way it is, you will find it much easier as well as more efficient than many other solutions. Another attractive feature Unitrends offers users is their variety of pricing solutions, which includes a handy licence per host and license per terabyte of backed up data. A free version is also available, which protects 8 VMs and an NFR version for VMware or Microsoft Certified Processionals. The Not for Resale (NFR) Edition protects 2 sockets and 2 physical servers as well as two application servers for as many VMs or files as a business needs.

Support from our award-winning team isincluded with all editions.
Ransomware threats are evolving faster than security software and IT admins can keep up. But that doesn't mean paying hackers a ransom, or that overburdened IT staff have to work even longer hours-instead, let Unitrends artificial intelligence (AI) watch over your data. Built-in to every backup, predictive analytics automatically monitor data characteristics, flag suspicious files, and alert administrators to threats. Now you can catch ransomware in the act, before the damage is done. Plus, for your ultimate peace of mind, Unitrends backup appliances are built on hardened-Linux, not ransomware's #1 target-Windows.
Uptime and retention requirements are increasing. But most organizations don't have the budget for a secondary site or the time to manage offsite storage. Let the cloud do the work for you. Unitrends backup appliances work with the cloud for long-term data retention and disaster recovery spin-up.
Don't run the risk of unplanned downtime due to a failed recovery plan. Recovery testing is key to maintaining uptime but is often neglected because it is too time consuming. Only Unitrends delivers automated Recovery Assurance testing, fully integrated with Unitrends backup appliances.

Review In my experience, backup software sucks. Normally, I chalk that up to a lack of exposure to non-crap alternatives on my part. Talking to backup admins and doing the maths on the licensing leads me to believe my original assessment is correct; there are precious few backups applications and vendors that don't cause some form of significant angst among their userbase. While at Spiceworld, I voiced this opinion.
Unitrends offers its backup software via two different routes: a virtual appliance and a physical one. The company sent me one of its backup appliances for review: a Recovery 833 designed to back up about 20TB worth of data. It has an MSRP of just under $50,000. I've also taken the time to play with its virtual appliance so that I can compare and contrast between the two offerings.
The heart of Unitrends' offering is its software. Whether offered as part of a virtual appliance or a physical one, it is really the software that you end up paying for. Unitrends uses both agentful and agentless backup methods. This allows Unitrends to back up operating systems via operating system images, databases such as SQL, Microsoft Exchange and so forth by being application aware. It will also back up virtual machines, virtual hosts, as well as file storage. They do just about every kind of backup you can imagine, from standard differential and incremental through to vaulting, P2V/V2V/V2P and "incremental forever" protection. (Incremental forever is Unitrends marketing lingo for near-continuous data protection in which data backed up is never more than 15 minutes old.)
Unitrends and I could have a very long conversation about our differences of opinion regarding an easy-to-use interface. Not being an enterprise backup admin, I personally found the Unitrends software to have a steep learning curve; it took me the better part of four days to figure out how to get the software to do everything I wanted it to do. I purposefully didn't use any of the tutorial videos before diving in to the software, as I wanted to get a feel for how intuitive it was out of the box. I did take a look after the fact, and the videos are actually quite good - if you start there, you'll be fine.
I'm not a big fan of the agent software. I really like the fact that the Windows agents install themselves without requiring a system reboot, so they get a cookie there. I otherwise find the agents to be clunky, counterintuitive, and completely lacking in what I would consider to be pretty basic setup functionality. Ideally, when I install an agent on a system, I should either be prompted with a nice wizard to connect to the relevant backup server, there should be a button that scans the network for appropriate backup servers, or both.
Instead, there's some complicated process involving selecting the appropriate backup server, registering with it, going over to the server software to configure backups and triggering it from there. Fortunately, I can generally get away without having to use the agent at all.
Despite my grousing, Unitrends' offering is still significantly easier to use than any of the other enterprise backup software I've had opportunity to work with, the virtual appliances I played with (version 7) were easier to deploy than I would have expected. Once I figured out the underlying logic behind how things were laid out, it proved easier and more efficient than System Center Data Protection Manager, Tivoli Storage Manager, Symantec's NetBackup, or even my beloved Retrospect. It absolutely wrecks Appassure.
