I would stagger the schedules as best as possible and use the bandwidth controls to limit upstream bandwidth to the cloud to ensure you don't cause a bottleneck. Is your request for CloudBerry Managed Backup or our stand-alone products?

Yes, I already use bandwidth management, but why have the contention. Also, if you set each server at say 1Mbps when ten are running you are using 10Mbps, but if six finish and four are still running they are not taking advantage of that 10Mbps.
But that brings up a new feature request, the ability to manage bandwidth settings across multiple devices. Right now you need to touch each device to change those settings. And/or have a bandwidth cap per site that gets spread across all running jobs. That is even better.

Hi Karlsen,
I have added your request to the following enhancement requests:
1. Chain backups across multiple devices
2. Bandwidth throttling settings for a site. To utilize the bandwidth at max during the backup window.

No ETA on any of them so far, but we'll keep you posted.

Thank you,
Anton
