Being able to jump in and restore a mailbox from tape by just dumping a folder somewhere is nice, but it just doesn't scale in terms of storage the way a db-driven mail system does.ĭon't flame me as an MS advocate. I see your point about some things, sure. Send a 1MB document to 1000 users on a flat, mbox-style mail server, and how much space is taken up on the server? 1000MB. If somebody in the organization forwards the Word doc to the remaining 900 people in your organization, how much space does it take on the server? 1MB. In a relational database-based, Single Instance Store-driven mail server, that document takes up exactly 1MB on the server. Say you send one 1MB Word document to 100 of your colleagues. The reason Exchange uses a database can be summed up in three words: Single Instance Store. Since you've taken things off topic, I'll grab the wheel and pull it right off a cliff. Just restore the frickin' files and move on with your life. I've only had to do it once (today) but the whole time I Was thinking how much esaier a mailbox restore on my OS X Server at home would be. We paid out the ass for "Enterprise" edition (to avoid the arbitrary 16gb limit on the mail store) and goddammit, I should be able to bring back a mailbox without its corresponding AD account without wasting a whole day setting up another server. They seem to think that since their "best practice" is to never ever erase any user account ever ever ever, that its okay to leave this gaping flaw in their enterprise groupware product. OBviously, the "Recovery Storage Group" feature is a VAST improvement over the old Exchange 5.5 way of bringing back just one mailbox (that being setup another server) but this is a MAJOR duh situation on Microsoft's part. Your choices are 1) 3rd party recovery tool (like Quest Recovery for Exchange) or 2) Build an ENTIRE OTHER SERVER and do a normal, full restore of the entire mail store so you can extract one measly mailbox. Why in the hell can't you restore a mailbox from backup using only the tools you already have if the user is no longer present in Active Directory? You can't even export the mailbox with EXMERGE. WIth that said, and without turning this thread into an Exchange bitchfest. Your point about putting more effort up-front into design is well taken, but thhat advice applies to any platform. Exchange is a great platform and scales well, so if the original people wouldn't do it, well then f*ck em. I work with Exchange, and think that the chances are better that they just had shitty architecture to begin with.
