Email Backup Pro is an easy to use backup utility for all the major Mac email clients: Apple Mail, Entourage x.V and 2004, Thunderbird, Eudora.
Its simple interface and “set-and-forget” features make it hard for a user to claim that creating a regular backup is too much hassle. (See an earlier, more extensive Hawk Wings review.)
There is only one new feature in the 1.1 release, but it’s a good one—support for multiple email clients:

Email Backup Pro costs USD 9.95 and a demo version (with scheduling disabled) is available from the developer’s web site
.

this is a bit silly, but aren’t there other full system backup options that simply include email (mail.app) as one of the things in the schedule? isolated email backups might make folks forget to back up everything else…
any thoughts on this, or top picks for all encompassing backup that includes all email/addressbook stuff?
What’s the difference between this and a program like Mailsteward that archives email?
Email Backup Pro: Compressed backups, cheaper, easily restorable.
MailSteward: Archiving not backup (i.e. a readable copy), searching, more expensive, more complicated.
