Veeam sizing session from Veeamon

Veeam Infrastructure Sizing

One of the key decision you have to make in planning a new Veeam deployment is in sizing the infrastructure. Correctly sizing the infrastructure to ensure that each of the Veeam infrastructure components servers has sufficient resources to perform its role will allow an optimally configured and trouble free environment. During VeeamON I attended a session on Veeam sizing by Tim Smith, I have pulled together my notes from the session and reviewed the Veeam documentation to give the following template for considering Veeam sizing decisions.

Veeam Components

The key components of the Veeam infrastructure you will have to consider in your sizing exercise are as follows:

  • Veeam backup server
  • Database server
  • Proxy Server
  • Repository server
  • Enterprise Manager server

Information Required

In order to plan your Veeam backup sizing you will need to gather some information

  • Size of source data – Required to calculate size of full backup
  • Daily rate of change – This is required to understand the size of an incremental backup. Can either be calculated assuming change rate as 10% of your total data size or from existing backup software
  • Number of VMs and disks to be protected and number of retention points required will also be needed for disk capacity planning which I will cover in a future post.

Sizing Veeam Considerations

Some considerations when sizing your Veeam environment:

  • All sizing information is contained in the user guide and best practice guide
  • Some sizing requirements refer to “Per Task”. Each disk that is backed up is a task this is not a per VM measure
  • Sizing requirements are specific to each Veeam infrastructure component
  • Sizing for each role is cumulative. For example if the server is both a Proxy and Tape server you will need to add the resource requirements for both together
  • The sizing information given in the user guide are minimums
  • The best practice guide estimates that doubling resources will half the backup window. Although this will of course be dependent on an any other bottlenecks
  • Staggering jobs can help to reduce resource requirements since some components are sized on the basis of number of concurrent jobs
  • Exact requirements will be specific to your environment, start with the recommended values access if it is meeting your requirements and amend as necessary. Then retest until you are satisfied with the result

Veeam Component Resource Requirements

Backup Server

  • 1 CPU core for every 10 actively running jobs
  • 4 GB RAM for every 10 actively running jobs
  • Minimum is 2 CPU cores and 8 GB RAM.
  • Disk space
    • Installation – 40GB
    • Logs – 3 GB log files generated per 100 protected instances, with a 24 hour RPO

Database Server

SQL Express is bundled with Veeam.  Consider using the full blown SQL if:

  • Protecting more than 500 VMs
  • Using files to tape extensively

When using the full version of SQL:

  • Up to 25 concurrent jobs – 2 CPUs, 4GB RAM
  • Up to 50 concurrent jobs – 4 CPUs, 8GB RAM
  • Up to 25 concurrent jobs – 8 CPUs, 16GB RAM

Backup and Replication Console

  • 1 CPU
  • 2 GB RAM

Backup Proxy Server

The proxy server is sized per task, a task is defined as a VM hard drive.  In effect this setting will determine the number of disks and therefore VMs that can be backed up at once

  • 1 CPU core per task
  • 2GB per task
  • 500MB of disk space per task

Backup Repository Server

This is again sized per task

  • 1 CPU core per task
  • 4GB per task
  • Detailed sizing will

Veeam Backup Enterprise Manager

  • Memory 4GB minimum
  • 2GB of hard disk space

Final Thoughts

Remember these figures are general guidelines ensure you account for time in your project to test and optimise resource allocation.

I will cover sizing for backup repositories in a future post.

The Challenge

Mouse trap

I was playing Mousetrap with my kids this morning and it got me thinking about data management.  In the board game you move around trying to win pieces of cheese whilst at the same time avoiding the mousetrap.

mouse in trap

As I got to be caught in the mouse trap for about the 8th time it reminded me how often in IT we are chasing the cheese – new projects, platforms and objectives whist neglecting the importance of data management. Data is the life blood of most companies these days but data management and protection is often an afterthought until there is an issue, aka you are caught in the mouse trap.

The solution

Firstly I would recommend not playing Mouse Trap with kids they always seem to win.  Secondly good data management is about recognising it’s importance from the inception of projects and creating a data management strategy, so as to avoid any pitfalls. Veeam are putting on one of the largest data management events of the year in Miami with their VeeamON event. The event features key data management experts, training opportunities, break out sessions, demos and key partners such as HPE and NetApp.

Event Detail

This years event takes place 20-22nd May in Miami Florida.  Some of the sessions I thought looked interesting included:

  • Ultimate Guide to Veeam Cloud Mobility: Tips, Tricks and Use Cases
    Veeam Backup & Replication Common Mistakes and How to Fix Them
  • Veeam Storage Integration Deep Dive
  • Architecture, Installation and Design for Veeam Backup for Microsoft Office 365
  • Automate Yourself Out of a Backup Job — Advanced PowerShell & API Usage
  • Veeamon 2019 banner

On the Veeam site you can see a full list of sessions.  Other reasons to attend include discounted VMCE training and the legendary VeeamON party which this year features Flo Rida. You can read more about the event at the VeeamON site

 

 

VeeamON Why Go

VeeamON Virtual

VeeamON is due to hit screens near you in the near future.  VeeamON is an online webinar held annually by Veeam covering data management tips and tricks, industry trends plus the latest product updates. The online webinar format makes it handy to fit around your work day, but like a transitional conference there will be a number of learning tracks available: Business, Technical or Cloud.

VeeamON Why Go

My picks for the sessions to watch will include Veeam Availability Suite 9.5 Update 4 . I like to see whats new with the product and the direction the team is taking it in.

Veeam predictions 2019 – Backup used to be boring, not now with an ever changing landscape of multi-cloud and massive data growth, I will be tuning into this one to see what Veeam thinks is around the corner.

Save your data securely off site with Veeam Cloud Connect – this should hopefully answer something customers regularly ask me about, Where can I offsite data? Should i use the cloud and how? Take a look at the agenda to see what other sessions are available.

There will also be chat rooms where you can ask any questions you may have.  I will be helping out in the chat rooms so pop in and say hi.
