Offline defragmentation creates a new database by copying all records
and tables from the old database into the new database. Because this is
a copy, defragmentation requires free disk space equal to the size of
the database (actually, you'll need 110% of free space).
Microsoft recommends a conservative 5 - 7 GB per hour for a defrag
operation, which means that your server will be offline for as long as
it takes, assuming no hardware failures will occur.
