I am trying to restore a 225GB database using backup exec, but does not seem
to be working. When I look at the processes in SQL one of the restore
processes is displaying ASYNC_IO_COMPLETION, the wait time seems to graduly
rising. As my restores have always worked in the past I've never looked at
the processes, is this normal? Or is this indicating a problem?
thanks in advance

Hi,
"Ths is normal while restoring a database with large size
The status "ASYNC_IO" comes when the RESTORE process create the blank
database. In your case
the process will stay for some time being you are creating a large database.
FYI, RESTORE process will create a blank database with the exact same file
sizes as the database that is being restored. ASYNCH_IO is the mechanism
used to create a blank database.
I recommend you to execute the restore with STATS option from the Query
Analyzer :-
Restore database <dbname> from disk='c:\dbname.bak' with stats=10

thanks for the info. :o) Turns out the box we were restoring it too was
running a bit slow. We tested a restore of a 15Gb database to test
everything was working correctly and then left the big restore restoring
overnight.
