I've talked about several different ways of doing your backups using Veeam here on the blog, but one of the most classic and even more used I did not have opportunity to comment: backup on tapes.
Although not the focus of Veeam, there is still the possibility of using the tool to keep our backups also on LTO tapes. Usually this is necessary when we need to keep a large number of backups or still to comply with some auditing standard in the company where you work. LTOs are still widely used for high data density in a single device (LTO-8 supports native 12TB on a single tape) and greater security of the recorded data. In addition, using tapes on the Veeam we can use the 3-2-1 Backup Rule
which helps us ensure that we always have a working copy of our backups.
Aiming at these possibilities as you use LTO tapes with Veeam, but before demonstrating how to add a Tape Server and create our backup routines, it is important to make two points clear:
- In Veeam tape backups are made by reading the backups of a job for disks. That is, you will not create a backup that writes directly to the tape reading the VMs of your ESXi or Hyper-V;
- In the Standard version of Veeam, tape support is limited in some functions. Only in the Enteprise and Enteprise Plus version that all options are available. You can check the differences between the versions by clicking HERE.
Before starting, to simulate a Tape Library in my lab I am using the StarWind Virtual Tape Library
which is a StarWind software that creates a virtual Tape Library by burning the files to disk. If you do not have a physical Tape Library to simulate this environment I highly recommend the software because it is very simple to set up and have a free version.
If you are using a physical Tape Library ensure that the drivers are installed and that Windows is recognizing your Library without any problem. In my environment it is recognized as follows:
With the Tape Library connected to your server, we can begin setup on the Veeam console. First we should go to the "Tape Infrastructure" section.
In "Tape Infrasctructure" we will click on "Add Tape Server" to add the server that the LTO is connected to. In my case the LTO is on the same server where Veeam is installed, but it is not mandatory.
In the first screen we will choose the server. If the server that is installed the LTO is not in the list click "Add New" to add the Veeam structure and choose it. Click "Next" to proceed.
In "Traffic" we can define traffic rules to control the bandwidth usage of this server. It may be interesting to define rules so that Tape Recording Jobs do not impact the performance of your network, for example. In my case I will not define any rules, but if necessary you can click on "Manage network traffice rules", create the rules and apply to the server. For more details on traffic control rules CLICK HERE. Click "Next" to proceed.
"Review" will check which components will be required for installation on the server. Click "Apply" to proceed.
The Veeam components installation process will begin on this server. When you finish click "Next" to continue.
In "Summary" you can check the option to start the inventory of your LTO after finishing the wizard. Click "Finish" to complete the process.
After adding the Tape Library we can already see the available tapes. In my case, since I am using a VTL, I have just created four tapes to use in the examples. Each tape is already set with up to 1,5TB in use.
In "Libraries" we can see the details of our Library. In my case it supports 96 tapes and I am using 4.
That's it for now, folks.
In the next posts I will go deeper into the LTO settings and create our job.
See you soon!
