EMC datadomain compresses 103TB of VM backups to 6.8TB using deduplication

john milner - top timico applications engineerJohn Milner is one of our top systems engineers specialising in Virtualisation. Over the last year he has been running an experiment to see the potential of using an EMC datadomain as the primary repository for VM backups. He has approximately 200 VMs (150 Linux and 50 MS Windows) backing up nightly to this appliance. What is amazing is that this appliance has managed to reduce nearly 103TB of production VM backups to 6.8TB using de-duplication and compression!

The below chart shows the actual data (blue) growing rapidly compared with the disk used to store this information (purple).

This allows us to retain data for much longer periods of time than usually possible. John’s next experiment will be to try the same using Veeam Backup and Replication as a comparison.  It’ll obviously take a while to get the results but I’ll let you know when we have some numbers to show.

More O2 LTE trial datapoints – very impressive upload times

Continuing with the day’s theme of the O2 LTE (4G) trials I found myself back in the Devonshire Arms with Cliff Saran of Computer Weekly. I’ll leave most of the story to Cliff and his column but I herewith provide you with the video footage of 4 more iPlayer streams – we could have streamed more but screen size becomes an issue.

At the Piazza in Covent Garden I uploaded a 298MB video in eight minutes at 9Mbps uplink speed. O2 LTE 4G upload speeds at the Piazza in Covent Garden
In the Devonshire Arms I videoed the process of setting up the iPlayer streams and then uploaded that video again to YouTube so that we could compare performance with the Covent Garden upload.

This time the file size was 795Megabytes
