Dmitry - Do you have any other tips for getting the best performance during backup and restore? Our current situation is a backup of the production database on server1 intiated on server2, with the backup file residing on server2. Server2 initiates the restore (using service manager), with the database being stored on the same disk array as the backup file. A 113GB production database produces a backup file of 99GB, and a newly restored database of 108GB. This entire process takes almost 48 hours. Thank you, Bob M..
