I don't know if i got your question right, but before, while using mbox, we had less users and much less quota, it was only 200MB now is about 1GB. And before we did not have a good backup system, had many problens. We pretty much change to maildir to be easie to make incremental backups and etc.
Sorry, the point of the question was simply whether you could use your old setup to help estimate whether there is actually any point switching from maildir? Sounds like you didn't have the same backup service back then, so you can't compare though?
Just pointing out that it's completely unproven whether moving mdbox will actually make a difference anyway...
And we are considering testing mbdox or sdbox. But still to earlier to make another big change like this.
Sure - by the way I believe you can mix mailbox storage formats to a large extent? I'm not using this stuff so please check the docs before believing me, but I believe you can mix storage formats even down to the folder level under some conditions? I dare say you did exactly this during your migration so I doubt I'm telling you anything new...?
The only point of mentioning that is that you could do something as simple as duplicating some proportion of the mailboxes to new "dummy" accounts, simply for the purpose of padding out some new format directories - users wouldn't really access them. Then you could try and compare the backup times of the original mailboxes (that the users actually use) with the duplicated ones in whatever format you are testing?
Just an idea? Good luck Ed W
