Time of restore for 105GB database

The time to restore a 105 GB database takes about 55 hours. and the size after restoring to a new database became 60GB which is my goal. The problem is the HO have 6 branches that are replicating all time to it huge data.(GOPRO Retail). I cannot stop the replication for 2 days. Is there a way to restore in a fastest way; or have you any ideas that may help? Navision version is 3.01

Use the table optimization instead of restoring [:)]

Don 't think it will stay 60Gb. After a few days it will grow and grow larger because of the versioncontrol.
