We have 7 backends:
                       400G  320G   81G  80% /mail/mail1
                       400G  273G  128G  69% /mail/mail2
                       450G  390G   61G  87% /mail/mail3
                       400G  322G   79G  81% /mail/mail4
                       400G  270G  131G  68% /mail/mail5
                       450G  397G   54G  89% /mail/mail6
                        50G  4.8G   46G  10% /mail/mail7


For mail1-6 incremental backup time takes between 2h and 7h, we suspect 
a storage (misconfiguration) issue.

Fulls take a lot longer, but I can't give you any time estimates now.

For the moment we don't backup the replica's.  Nor use them.  But we 
could do it.

We are 'planning' a storage migration too the coming months.
