Veeam Data Cloud for 365

[ekhouser614]

I cannot seem to find the "best" place to post this question as there seems to be no support forum for the VDC for 365 product. Maybe someone here can answer this though. We are migrating away from our VBR for 365 architecture and going with the VDC for 365 product. Can anyone elaborate what the expected throughput would be for simply backing up mailboxes from 365 into Azure storage for this product? We enabled it for roughly 45 users with the average mailbox being 20 gig and very little in OneDrive but this thing is incredibly slow based on the progress so far. There have been mailboxes that at the time of this writing, been backing up since July 2, 2024 and today is July 10th! Any feed back as to what others may have experienced while understanding this may not be the correct forum.

This is not a support forum either. The forum is run by our product management team.
If you require technical support for VDC or any other product, you must use our official support portal: https://www.veeam.com/support.html

You may try to disable mailbox throttling --> https://www.veeam.com/kb4198
However, since Veeam folks in this forum do not have access to the logs, I cannot confirm that throttling is the reason why the job appears to be hanging. If a job runs for 8 days, it likely indicates another issue. Thus, I highly suggest reaching out to our official support team to resolve this situation.

Thank you,
Fabian

As a note, this is not a support request and I'm simply posing a question to anyone who may be able to say either what they experienced, or what the specs are for throughput since there is VERY little on the VDC pages for info. The job isn't "hung" as it is incrementing number of processed items throughout the day. The throttling link you sent was already completed days ago with little to no improvement. I am in the process of opening a ticket, however, it would be good to see what others have experienced and the reason for making this post.

Hi Eric,

Thanks for sharing. Fabian is right that the best thing to do will be to speak to support. Although the mailbox size averages are about 20GB you're saying, and very little in OneDrive, one of the major impacts is the amount of items being processed as that has a massive impact on the amount of API calls being made.

Definitely worth raising with support to make sure the bottleneck is on Microsoft's side here, and that there's nothing uncharacteristic about the job that might be impacting performance.

Thanks,
Michael

VDC is super slow the first time it runs a back up policy. It is a turtle compared to on prem Veeam for M365. To backup 90 mailboxes (approx 250GB) it took 2 days. To backup 1TB of SharePoint documents it took almost 4 days. Thankfully after the initial run of the backup policy it does run a lot faster. If you create a new backup policy for the same data you already have in VDC it does take again a few days as indicated above. I do not know why it takes so long if the data is already in VDC repository.
