Hi halford,
First of all thanks very much for your reply, i try as u said above to take backup.
Still i am getting error. I mention it below.
Backup Server: 4.172.1.1: The value of 'reserved pages threshold' has been set to 85%.
Backup Server: 4.172.1.2: The value of 'allocated pages threshold' has been set to 40%.
Incorrect syntax near 'C:'.
