Veeam – Backup Copy „Block is not initialized. Failed to download disk.“

Recently a customer reported an issue with a backup copy job. At this customer we implemented a new leased line with synchronous 1Gbit/s bandwidth from the main site to a secondary site. That gave us completely new possibilities regarding the backup of data and making it available. There is no need for a WAN Accelerator anymore, we can replicate VM’s with Veeam directly to the secondary site. And also backup copy jobs to this site go now A) directly and B) in a regular manner (what wasn’t possible before because of lack of bandwidth).

By the beginning of the last week, around the 30th of May, one backup copy job started to fail. This job contains all VM’s and should backup copy the data once a day to the secondary location. But one server, the main fileserver, failed with this error message:

Error: Block is not initialized. Failed to download disk. Reconnectable protocol device was closed. Failed to upload disk. Agent failed to process method {DataTransfer.SyncDisk}.

First i thought, ok, that can happen. No worries. After the second failure i did some checks and also opened a support case at Veeam support. If you don’t know how to collect log files for a Veeam support case, please have a look here.

Veeam Availability Suite – Quick Setup Guide

Today i was working in my homelab. I installed an availability solution. It was a quick thing, no complex setup and configuration, but a straightforward installation. Even if its „just“ my homelab, i want to know that my VMs are safe and secure and that i can see trends about space utilization and other parameters. How do you achieve that? With installing Veeam Availability Suite v9.

Veeam Avalability Suite v9 - Setup Screen

Just to clarify, the time to create the screenshots took longer than the actual setup of this availability solution. The setup assistant will guide and help you through the setup, it’s really easy, and after few minutes you are ready to go and take the next steps.

What is Veeam Availability Suite?

With this software suite you receive to main components. First of all you will get the very well known Veeam Backup & Replication. This is the doing-backups-part of this suite. Furthermore you get the second component which is Veeam ONE. With Veeam ONE you will get the monitoring, reporting and capacity planning part of this software suite.

Why not only creating backups?

There is for sure not just one simple answer, but let my try to explain. With Veeam Availability Suite you will ditch your legacy backup solution and get real availability for your servers, your data and your business. Veeam Backup & Replication is used to setup the backup of your virtual infrastructure. Through Veeam ONE you get the whole monitoring, reporting and capacity planning. In a single pane of glass you get instant reports, you can monitor your infrastructure and get some insights in the capacity. With this you will find out some trends (for example when a specific data store runs out of space), even before it actually happens.

How do i install this software?

As i already mentioned it’s a really easy process. The setup assistant will ask you some things, but more or less it’s next, next, finish. For sure you can specify the setup steps and configure other ports as the recommended ones for example. The setup assistant gives you this ability if you want. If you are fine with the standard settings, you can leave them and go on.

The following guide line will show you how easy the setup process is. I did an easy deployment, all stuff centralized on one server because my lab is not that big (at the moment). I will discover the points mentioned above, for example the extended screens of the setup assistant, to cover all your needs.
