Exchange 2007 Mailstore Defrag

I have five mailstores and am running low on space on mailstore one. The drive is 200GB in size and the mailstore is listed at 190GB. The actual size of the data on it is only 70GB so I need to run a defrag. To run the defrag I will run C:\program files\microsoft\exchange server\bin Eseutil /d c:\program files\exchange server\mailbox\<storage_group_name>\<database_name>.edb
My query is with the research I have done:
1) I have read though that I require 110% space for the database. Does this mean I will not have space to do a standard defrag and would need to redirect to a new drive?
2) Do I need to unmount all mailstores or just this one?

you will need to do it on another drive if you haven't the space on the original.  you can redirect it a different server.  there are other parameters that can be found here http://exchangeis.com/blogs/exchangeis/archive/2007/03/26/eseutil-a-quick-and-easy-tutorial.aspx or on msdn.

You only need to dismount the store you are working on.

I have a spare drive with 100GB on it on the same server. Will this be enough?
Have you any idea on the length of time required for this action based on sizes above? Are we talking hours?

you will need a drive at least 110% of the database size, so one about 210GB, but i would allow a bit more to make sure.  It will takes several hours, I haven't done one for a while but i think the rough standard is about 4Gb/hr but that will depend on memory, processor speeds etc.

Are you definite that the 110% estimate is based on the current mailstore size and not the actual(i.e.70GB)?

That is the rule that I have always followed.  If you use the switch to create a backup then it will copy the database file and work on from that.

Defrag went fine. It appears to be only the actual size of the database that you must provide space for rather than the original exchange size listing. Mine only required 50GB in the end
