How to produce good documentation – Part 5 – Diagraming your (Veeam) Backups

So it’s just been a little over a year since Part 4 of my how to document series was posted. I hoped to keep adding to the series, but at the same time, only do it when I felt I had relevant content to share. So this post is to show how I have documented some recent backup configurations. Note: I mainly work with Veeam, but hopefully this will give you idea’s of how to present the setup of your other backup software

Below are the previous posts;

The challenge

Note: The Visio file for these examples can be found at the end of the blog post.

Your backups evolve over time, as does your environment. Your backup schedules become more complex, and its hard to remember, what does what.

As past of my job, I setup backup solutions for customers, and then have the task of documenting how they are setup. I used to do this in a table format. It was quite simple

  • Backup/replication job name
    • Services backed up
    • Job settings
      • Storage/environment used

When you have a number of backup jobs, you have a lot of jobs and information to dig through. Its not user friendly.

Veeam backup job settings table 1 Veeam backup job settings table 2

So I re-visualised the way to present the data, I still have the detailed tables, however I also have three Visio diagrams

  • Backup Architecture setup
  • Backup and Replication jobs – Servers/services included
  • Backup and Replication job settings – high level

Veeam v9 Backup and replication / ONE upgrade from v8

This is just a quick post showing the upgrade process of

  • Veeam Backup Enterprise Manager
  • Veeam Backup and Replication
  • Veeam ONE

I didn’t hit any issues with the upgrades.

  • It’s always a good idea to reboot your servers before any update

And plan for further updates once the Veeam upgrades have completed as well.

Veeam Backup Enterprise Manager

  • I had to install .Net Framework 4.5.2 to continue the upgrade, which required a reboot
  • I upgraded from v8.0.0.817 (so not the latest patch)
  • I was asked to confirm the SQL Database upgrade
  • The server needed rebooting at the end of the upgrade

Further ESXi 6.0 CBT bug info – Reset your CBT!!!

Following on from the recent (November 2015) ESXi 6.0 CBT bug, which has now been fixed in the latest released patch ESXi600-201511401-BG, some further information has come to light, provided by Anton Gostev, of Veeam.

You can read the snippet of important information from the Veeam forum post following the issue (Official Veeam KB2075);

All, we have completed the first day of testing in the same exact lab and using the same heavy write I/O test that made the original issue easily reproducible. After a few TB of increments, the above-mention patch appears to fully resolve the original issue when installed on ESX 6.0 Update 1a build 3073146.

However, we found that simply installing the patch is not sufficient, and CBT reset is required for all of your VMs. This is because existing CBT map files may contain issues created earlier due to the original bug, which may result in inconsistent full backups in future. Having CBT reset will also force the following job run use "full scan" incremental pass, thus fixing any existing inconsistencies in backups and replicas, as discussed earlier in this topic.

Provided CBT reset has been performed, Active Full backups is not required.

Performing Active Full backups by itself cannot be considered as a substitute to CBT reset with this particular CBT issue.

Thanks!

You can either follow the CBT Reset instructions from Veeam or look over to Chris Wahl’s latest blog post “Resetting VMware’s Changed Block Tracking (CBT) File with PowerCLI”.

Last Minute VeeamON:Forum London plug!!!

Oops I forgot to post this last week as I was busy finishing off my Cisco UCS Blog posts, but still if you read this in time, maybe you’re in the area and can nip down, or pull a sickie and get in, the event will be worth it!!

Personally I was all booked up for a trip down to the capital from the sunny north of England, however due to unforeseen circumstances, I cannot make it. Which is a shame, as I’ve been speaking to a few vendors that will be there, and it sounds as this will be a properly organised event, and not something thrown together.

So head on down and enjoy it for me!!!!

ESXi 6.0 – More CBT woes

Post update 14th May 2015

VMware have released a hotfix KB2116126.

Removed information regarding old CBT workaround for Veeam is incompatible

_________________________________

So it’s come to my attention that the new and mighty ESXi 6.0 has a CBT fault as well. This time its effects are different than previous versions, but causes you backups to either fail, or take a considerably longer time to complete.

Here is the official KB from VMware: KB2114076 – Backing up a virtual machine with Change Block Tracking (CBT) enabled fails after upgrading to or installing VMware ESXi 6.0 (2114076)

The Cause

Below is VMware official note on the issue, which isn’t very promising, and will affect any backup technology using snapshots within VMware.

This issue occurs due to heap exhaustion when attempting to enable Change Block Tracking (CBT). 

If a virtual machine with a large number of virtual disks reached an upper threshold, enabling CBT fails because of heap exhaustion. This issue also occurs with multiple virtual machines with CBT enabled. In case of Windows virtual machines with VSS enabled, taking a quiesced snapshot creates double the amount of memory overhead.

Note: The virtual disks can be spread across virtual machines or can be in a single virtual machine.

You can look in your VMKernel.log from the host the affected VM is on to see various warnings about CBT.

WARNING: CBT: 191: No memory available! Called from 0x418010db750e

Here I’ve used the System Centre Configuration Manager Trace32 Tool for viewing the VMKernel.log
