Extremely slow reading from Office 365 cloud

Veeam Logoby Robvil » Fri Nov 24, 2017 6:41 am

Hi,

I have opened a case, 02394834, on this.

I just noticed my O365 backup takes forever now .... as in 17B/s in transfer speed ... so a simpel incremental never completes.
It has been running fine until 10/13/17. After this date the transfer speed is nearly zero and has never completet as session.

Ohh, it´s not a local bandwidth issue.

Anyone seeing this?

Is Microsoft somehow inforcing speed transfer limits?

Regards
Robert

Hi Robert, what Veeam Backup for Office 365 version are you using? Any chance this started to occur after the upgrade? Here's another topic with similar issue for more information.

1.5

It helped to lower the active threads from 64 to 10.
Now 47GB data has been backup.

Robert,

What is the speed that you see now?

(PS: you might want to play a bit with those active threads. It is difficult to tell you a formula what the ideal thread # is but playing a bit with it until you find the best setting for your environment is certainly my advice)

Good to hear, although using all the bandwidth is maybe something you also don't want :-)

Note that in 1.5 you can set limits to your bandwidth per proxy: https://helpcenter.veeam.com/docs/vbo36 ... tml?ver=15
