ExaGrid vs Data Domain speed question

[matai]

Currently we're backing up from a Nutanix cluster to a Data Domain 640 with BOOST. The BOOST definitely increased our backup speeds. With four concurrent jobs, the speeds were 33 MB/s, 30MB/s, 29MB/s and 32MB/s. If only one job is running, the speed is around 85-90MB/s.

I'm trying to sell upper-management on migrated to an ExaGrid backup repository. I'm wondering what sort of backup and restore speeds we would get with that. Does anybody have any guesses or examples they could share?

A big issue for us is restore speeds. We had an issue over the weekend and I'm restoring a 100GB folder right now and it looks like it's going to take a long time at 3MB/s.

Thanks!

Hi,
as partner of both vendors, we obviously cannot suggest you one over the other.
What I can personally suggest you, since you already have the DD working at your environment, to try and have a POC of Exagrid: in this way you can test both on your environment rather than reading performances on paper. then you can take your decisions.

Matai - since the most recent Veeam backups are kept on the ExaGrid Landing Zone (think high speed disk cache), Veeam restores of all kinds are not slowed down by rehydration (having to undo the deduplication).

To get more info on what kind of restore speeds you can expect, check out ESG Lab's reports covering Instant Recoveries, full restores, and ExaGrid-Veeam Accelerated Data Mover:

I am an ExaGrid employee working in both engineering and product management - don't hesitate to "message" me if you need any assistance.

Lastly, I'll 2nd Luca's suggestion about a proof of concept - its the best way to prove the faster Veeam restore times with an ExaGrid repository. Please do contact ExaGrid to explore a proof of concept

Regards,
Tom.

I have a DD2200 (way smaller than the 640). I get the same restore speed on SAS 15k in Raid10 simply because i bet you are restoring a bazillion of small files which require IOPS.

Try to restore a single big file, you will get the same performance as the backup (80/90Mb/s)

You can either restore the whole vmdk then get the file once it is mounted, it will be probably be quicker.
