Well, you can still use an offline backup and restore process, or you
can use the "tar" exporter for all your accounts to obtain a suitable
dump per-mailbox.

I currently use the former[1], but will be moving to the later at some
point soon since it gives me much more efficient storage of the data and
metadata in our backup system.[2]

I don't know your clients, obviously, but generally running a nightly
backup with a few minutes downtime should be sufficient for any business
that isn't world-wide...

Footnotes: 
[1]  With LVM snapshots, so downtime is ~ five minutes.

[2]  BackupPC, which pools common content, so will only record the (much
     smaller) changes each time.
