Thanks for your great product,
Just one question, first backup (full) is very slow with big mailboxes (2/3 hours per big mailbox and we may have hundreds of mailbox to backup)
Bandwidth is not a problem, we have 300Mb/sec and VBR doesn't not use all the bandwidth.
So I think it would be possible to optimize backup time by parallelizing mailbox backup.
For exemple on-premise when we import multiple mailbox to a PSP we run 3/4 scripts at the same time.
Exchange engine is able to manage this.
Thanks for your answer.
