XFS – Performace

Last article about XFS.

In the previous two paragraphs I explained how to configure and set-up the XFS repository on Veeam Backup & Replication v.10 (VBR)

Today let’s see how perfectly the XFS linked-clone technology helps VBR to transform the backup chain. 

Particularly let’s see what happens with Synthetic Full.

What is Synthetic full?

It’s a smart way to help VBR to create a Full Restore point downloading just an incremental backup from production.

To be very short the process is composed of two phases.

Firstly it creates a normal incremental backup data, secondly it creates a full backup file stacking all previous backups (full and incremental).

This process normally needs a lot of work because it is necessary to copy, paste and delete the unnecessary blocks to create the synthetic full.

With XFS integration, we do not move any block because the filesystem will re-point his metadata creating a full Backup in one shot .

The result is super fast  Full Backup creation.

Let’s see with an example:

Full Backup has lasted 7 mins (Picture 1)

Picture 1

Incremental Backup has lasted 2 mins and 30 sec (Picture 2)

Picture 2

What about a Synthetic Full? 

Picture 3 shows that it needs less than 30 seconds!!!

So Amazing technology  and Veeamzing integration!!!

  1. I have been browsing online more than 3 hours nowadays,
    yet I by no means discovered any fascinating article like yours.

    It is pretty worth enough for me. In my view, if all website owners and bloggers made
    excellent content material as you probably did, the web will probably be much more useful than ever before.
