You can use the Recovery Wizard to guide you through the entire process of restoring a database instance.
You can start the Recovery Wizard on a Windows-based server to restore data on either a local or remote server.
The Recovery Wizard always proposes the quickest procedure for recovering lost data. Complete data backups are read first; then, if necessary, incremental data backups and log backups are read.
To make sure that the data is recovered as quickly as possible, data backups can be read from multiple backup media at the same time. The number of media in a group of parallel backup media does not have to be the same as the number of parallel backup media used for the original backup. Even a backup made to single medium with succeeding media can be restored in parallel. You can considerably reduce the restore times by using up to 32 tape drives.
Log backups cannot be restored in parallel.
In the Database Manager GUI, choose Instance ® Recovery ® Recovery... .
Choose Next to start each of the required recovery steps.
