Not clear whether you're referring to the mail system or the backup
system, If it's the former, then of course we are all on servers but
not all of them are IMAP, however my point was specifically in relation
to a question about backing up IMAP accounts. If you mean that not
everyone has a backup server, that's true but irrelevant. If I was
backing up to a local disk my backup technique would be exactly the
same.

The idea that "disks are so large now that we can stop worrying about
running out of space" is one I've been hearing for the past 40 years.
Oddly enough, the size of email messages seems to grow as fast as the
space available for their storage, but even if that weren't true, you
mean you copy 6GB of (mostly redundant) data over your network
connection every time you do a backup? I don't see the point.

So you can store up to 10 backups. Using an incremental scheme would
get you a lot more, and you'd use much less bandwidth in doing it. You
must do whatever works for you, but the discussion is about what if
anything Evo itself should support. My view is that it would be a waste
of scarce developer time to code some application-specific backup
scheme when it's not needed.
