Re: Slow backup performance

Post by aich365 »

From Support:
I have received the following information for our QA team - this “Last Backup” property was not meant to be displayed in the backup history at all - for example, it was not shown there in version 4.

This property will be removed from the backup job report that is displayed in "History" in version 5b.

Hi Clive,

That's right, it's a small bug which we'll fix with the next product update. Thanks for bringing it to our attention!

I am trying to do full backups and the performance is atrocious! I am seeing KB/sec performance here on a 1 gig pipe. I've configured multiple backup accounts, but it doesn't seem to make any difference.

This is of course not normal, so you should open a support case to investigate. Thanks!

I've opened a case (04722584), but I am starting to think maybe I am seeing slow performance due to the repo being ReFS? Just read over the best practices page and see NTFS is recommended.

Definitely not... ReFS performance is identical to NTFS.

@Gostev is correct. ReFS is supported and the performance should be identical. What is the bottleneck that you see in the session log?

It’s showing source as the bottleneck. Write performance for one particular job is 436 KB/s.

So it means that the problem is at the O365 side of things. Do you have already a support call, because this can have many reasons including configuration on your side

Well, it appears that Microsoft is throttling us.

Yeah, but that seems like a lot of throttling... Did you had a support call?

@mcvosi
We did had similar problems for some jobs. And almost all of them were due to misconfiguration on O365.
For example: We have a customer who had a script running, creating millions of versions of sharepoint items. The backup was running forever, as every item was just a few bytes but there were just too much of them. Maybe something like that could also be a problem at your site. Did you compared the amount of items beeing backed up with the actual size?

Not sure how it could be a misconfiguration though. I mean, the only other thing running is AD Audit Plus, which I sometimes see notifications about throttling as well.
