Backup & Restore

Q/Tos is an Automated Backup/Restore Manager that catalogs and tracks all backups (BACKUP, BACKUP2 and PAK), automating recovery of critical data. This product has outlived many rival products with the same end goals while offering superior solutions.

Backups are organized by backup templates called master datasets.  The master dataset contains all of the criteria needed by the backup program such as the tape volume requirements, security, retention, etc.  When a backup is started Q/Tos uses the information in the master dataset to create the tape define to pass to the backup process.  As the backup progresses Q/Tos records every file and object backed up, be it Guardian, SQL/MP, SQL/MX or OSS.  The backup specifics are stored in a version dataset record and all file/object records are linked to the version dataset.  Q/Tos creates event messages notifying the start, end and results of each backup.

Restores are started by Q/Tos using the information in the version dataset to create the tape define used by the restore program.  Restores can be started from the QTOSCOM line-mode program or from the Q/Tos GUI.  When the restore is started from the GUI the options are selected by clicking check boxes and typing in text boxes.  Common configurations can be saved as restore profiles that will configure the options when the profile is selected.  The output from the restore is displayed in a window on the PC, removing the need to look for the output in the spooler.

To complement our Backup/Restore Manager, we also have a Rapid Restore product which transforms the serial media retrieval method to a random access method, restoring files in only 10 to 15% of the time it takes the nonstop restore program.   Q/Restore is particularly useful when retrieving files from LTO tapes.

Other products provide data storage and recovery for spooled data, Q/Sparc and  Q/Spool, a general utility for the HPE NonStop spooler environment.
