Hello and welcome back. This is the last part of my short series of posts about tuning backups.
I want to show you the performance, Backup Exec can reach.
Disclaimer:
Of course, this is neither an agreement that these performance values can be reached in every environment on the globe, nor that faster environments are not possible. It’s just a glimpse into what we do in our day-to-day business.
In the first part of this series we did some backups of test data to get a baseline of the performance Backup Exec can reach, if the environment is configured appropriately.
During the second part of the series we backed up a virtual machine hosted in a VMware environment via network.
The third part shows, how to change the transport mode from LAN to SAN.
Part four of the series introduced the PingUs Performance Tuner, a tool that can assist in tuning registry keys on the backup server to increase the overall performance when backing up VMware data.
In this last post I want to show that the performance we achieved in the demos before can also be reached, when multiple jobs run in parallel.
Note:
Of course, this performance cannot be reached, when too many jobs run in parallel, because at some point the infrastructure will be saturated and no longer be able to transfer more data in parallel.
Nevertheless, two, three or even four jobs should be running fine in parallel. But as always: please test this in your environment and find the best configuration for your needs.
The Setup
Our “test candidate” is again the virtual machine running Windows 7 including Office 2013 and is doing some background tasks that produce load and files on the machine.
It is virtualized on a VMware vSphere 6 ESXi cluster (2 nodes) that uses a HPE MSA 2040 SAS as its shared storage. It’s the same storage, we also used in part one of this series. Regarding part two, three and four of this series, nothing of this setup has changed.
The Backup Process
Basically, all I do in the video is to start two jobs in parallel and monitor the overall performance of both jobs.
The Movie
You can watch the video recorded for this post on YouTube:
Thank you for reading this little series of posts and I hope, you found some interesting stuff here.
