Re: vSphere 4.1 and USB Passthrough

If Trev was going by the Veaam job stats, they don't reflect actual transfer rates.

Those stats are basically: Entire VM Size / Time taken.

Given the entire size of a VM is hardly ever backed up, they're not really useful.

What I'm hoping for in V5 to get an actual, real-life transfer rate is something like:

(
- TOTAL Size of VM Files -> LESS
- Zero's blocks not backed up -> LESS
- Blocks not backed up due to compression -> LESS
- <Any other nifty technology which reduces the amount backed up> -> PLUS
- Any overhead traffic required (eg for replication)
)
DIVIDED BY
(
- Total JobTime LESS
- Time taken to prepare job LESS
- Tme taken to take and remove snapshots
)

The actual numers of each of these items would be nice to see as well as the metrics of what makes up the VBK/VBR files (so we can report what we're transferring / saving to management etc)

This will not be in v5 for sure.

Slow Backup to USB

Post by ideo-fdufour » Jan 11, 2011 4:35 am

I'm evaluating Veeam Backup & Replication, so that's my first step with the product, and wondering if my backup job setup is maximize...

Setup:
vSphere Essentials and Veeam Essentials.
Veeam installed in a VM on the ESX server.

Backup job:
Virtual Appliance
VM to backup: Exchange 130 Gig (2 vHD)
Destination: USB drive on Veeam VM (Z:\VeeamBackup\Exchange)
Backup Mode: Reversed incremental
Enable application-aware image processing (enabled)

I got poor processing rate (3MB/s) took more than 11 hour to backup the 130 Gig VM

Is there something wrong with my backup job setup ?

Any input will be much appreciated!!

Regards,
Fred

Hello Fred,

I'd say it is somehow expected with USB Passthrough enabled, please review this topic for more information. If I were you I would change your destination target to any network share/linux box/DAS to get higher performance rates.

Thanks!

You can check the hardware matrix on VMware site for supported devices, but I'm pretty sure it should work.
