further action by the client. The client merely accepts the data coming from theserver and restores it to the destination named on the restore command.Using the command line client, an example of an unrestricted wildcard commandwould be:An example of an unrestricted wildcard file specification would be:/home/mydocs/2004/*An example of a restricted wildcard file specification would be:/home/mydocs/2004/sales.*Standard restore processThe standard restore process (also known as classic restore) is outlined below.1. The client queries the server for a list of files backed up for the client file spaceyou want to restore.2. The server sends a list of backed up files that match the restore criteria. If youwant to restore both active and inactive files, the server sends informationabout all backed up files to the client.3. The list of files returned from the server is sorted in client memory todetermine the file restore order and to minimize tape mounts required toperform the restore.4. The client tells the server to restore file data and directory objects.5. The directories and files you want to restore are sent from the server to theclient.No query restore process1. The client tells the server that a no query restore is going to be performed andprovides the server with details about file spaces, directories, and files.2. The server sorts the data using an internal sort table which minimizes tapemounts.3. The data to be restored is sent to the client. File and directory objects stored ondisk are sent immediately since sorting for such data is not required beforerestoring it.4. You can use multiple sessions to restore the data. If the data resides on multipletapes, there are multiple mount points available at the server. The combinationof using the resourceutilization option and MAXNUMMP allows multiplesessions. See “Resourceutilization” on page 327 for more information.If the restore process stops because of a power outage or network failure, theserver records the point at which this occurred. This record is known to the clientas a restartable restore. It is possible to have more than one restartable restoresession. Use the query restore command to find out if your client has anyrestartable restore sessions in the server database.You must complete a restartable restore before attempting further backups of thefile system. If you attempt to repeat the restore that was interrupted or try to backup the destination file space, the attempt will fail because you did not completethe original restore. You can restart the restore at the point of interruption byentering the restart restore command, or you can delete the restartable restoreusing the cancel restore command. If you restart the interrupted restore, it willrestart with the first transaction, which might consist of one or more files, notcompletely restored when the interruption occurred. Because of this, you mightreceive some replace prompts for files from the interrupted transaction which werealready restored.Chapter 5. Restoring your data 125
