VeeamON Virtual

VeeamON virtual is due to hit screens near you shortly.  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 virtual

My picks for the sessions to watch will include:

Veeam predictions 2020 – 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.

Designing for Veeam at scale – Organisations are facing increasing volumes of data, so how do you scale Veeam infrastructure when your environment runs into thousands of VMs.  This session provides best practices to ensure your infrastructure scales

Winning the war on ransomware – Backup is part of your defense– Ransomware continues to be a real threat to businesses, check in to this session to see if your strategy is sufficient to protect your organisation against Ransomware

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.

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 sizing session from Veeamon

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.

VeaamON – Keynote Summary

Data Importance

  • Data is the life blood of an organisation
  • It is a necessity for data to be always available
  • We are experiencing an unprecedented level of data growth
  • Companies need a trusted data partner

Veeam achievements

  • Veeam is now a plus 1 billion dollars company in terms of annual revenue
  • They have now acquired more than 350 thousand customers and continue to grow

Trends

  • Change is constant
  • Cloud, mobile, edge IoT are current industry trends and have a direct bearing on data management
  • Microsoft took to the stage and amongst other things discussed new storage technologies they are investigating to deal with massive data volumes that are being produced. Project being investigated include storing data on glass and within DNA!

Vision

  • Veeam were a key player in the virtualised data centre and now intend to repeat that with hybrid cloud data management
  • Veeam estimate 73% of its own customers operate a hybrid cloud strategy
  • They intend to keep to the core Veeam qualities of simplicity, reliability and flexibility
  • Vision statement – “To be the most trusted provider of backup solutions that deliver cloud data management”
  • Veeam will offer a data management solution for virtual, physical, SAAS and cloud work loads.

Technical Announcements

  • With Veeam – This new programme will bundle Veeam with HCI and storage vendors hardware together to allow tighter integration, more features and faster deployment.  The products will be able to be ordered with a single SKU and there will be a single point of contact for support  
  • Nutanix Mine – Initially announced at Nitanix.NEXT is a turnkey solution offering Nutanix and Veeam Availability.  Nutanix Mine is the initial offering of With Veeam along with Exagrid.  Mine is currently in beta testing with select customers
  • Veeam Orchestrator v2 – The automaton and orchestration software expands its capabilities including:
    • Audit and remediate SLA compliance
    • Automatically leverage both backup and replica protection data for use cases such as DevOps, patch and upgrade testing, analytics and more.
    • Role based access control to allow business units to perform their own testing
  • Scale out repository – coming in the future is the ability to use cloud object store as a direct target for backups
