Today we are talking about retro-software... As many of you are already using Exchange 2010, you might not be interested in the information given in this post. In fact the Recovery Storage Group has been removed from the Microsoft famous email server starting from the 2010 version.
Anyway, if you are sticking with a previous release then I believe you should - at least - know something about recovering mailboxes from a backup. In my experience, whenever I knew about a possible disaster recovery solution, the disastrous situations never occurred. It's like a protective talisman!
So, here we are. Read this post and take it as an amulet, protecting you from disastrous situations!
What is the Recovery Storage Group?
The Recovery Storage Group (RSG) is a storage group (!) that can be used to mount a backed-up copy of a mailbox store in your Exchange environment.Typical situation:
1) Your Exchange is working and should continue to work;
2) You need to recover a deleted mailbox or single email;
3) You do have a back-up copy of the mailbox store;
4) You need to recover that back-up and put it in a safe position to extract mails with ExMerge.
Confused? You shouldn't, because the operation is quite easy - even if could be quite time consuming.
