The backup (STORE) and recovery (RESTORE) processes have similar steps. Only the specific commands and command options differ. The structure of your organization determines who performs the STORE and RESTORE steps. The basic steps include the following:

  1. Determine what you want to store or restore. Refer to "What Should You Backup?" in this chapter.

  2. Identify the storage device. Refer to Chapter 3, "Preparing Storage Devices."

  3. Mount the media on the device. Refer to Chapter 3, "Preparing Storage Devices."

  4. Prepare the system for store processes. Refer to Chapter 4, "Preparing the System." for preparing to STORE. Refer to Chapter 11, "Restoring Files." for preparing to RESTORE.

  5. Issue the STORE or RESTORE command with the appropriate options. Refer to Chapter 5, "Storing Files" and Chapter 6, "STORE and TurboSTORE Command Options" or Chapter 11, "Restoring Files."

  6. Reply to the console (media allocation) request. This may not apply if you are using labeled media. Refer to Chapter 8, "Handling Media Requests."

  7. Remove the storage media. Refer to Chapter 8, "When STORE is Complete," and Chapter 11, "Restoring Files."

Helping Users Store and Restore Files

Storing and restoring files is not limited to system personnel. Account managers can store and restore any file in their accounts (except files with negative file codes) and all users can store and restore any file in their logon groups and accounts. While these other users can enter commands to store and restore at their terminals, they usually do not have access to backup devices.

The steps described below summarize how the operator and a user work together to store and restore files. The order in which you perform steps of the procedure may vary. For example, you may see a media request before the user hands you the backup media, instead of the other way around.

  1. The user gives you empty backup media onto which to store disk files, or the user gives you the STORE media from which to restore files to disk.

  2. You mount the media and prepare the device.

  3. The user enters the FILE and STORE or RESTORE commands.

  4. You check the console for a media request.

  5. If the system does not automatically answer the media request, you must reply to it.

  6. When the process is complete, remove the media and return it to the user.

  7. As part of your regular routine of retrieving, separating, and distributing reports, collect the report describing the stored or restored files. Either file the report in the appropriate pickup bin, or keep it until the user comes to get it from you.

Table 2-1 "Task Roadmap" provides a roadmap for system managers and operators of the chapters that pertain to their particular tasks.

NOTE: Non-Large files are those files with a file size less than four Giga Bytes, and Large files are fies with a file size greater than or equal to four Giga Bytes and up to one Tera Byte.From MPE/iX 6.5 onwards, TurboSTORE/iX supports store and restore of Large files. As of MPE/iX 6.5 release, the types of Large files supported are Fixed ASXII and KSAM 64. Please note that these files cannot be restored on a pre-6.5 system.

Forward Compatibility: Any media stored using Turbo Store from a previous version of MPE/iX can be restored using the TurboSTORE/iX 6.5.

Backward Compatibility: Any media stored using TurboSTORE/iX 6.5 can be restored onto a pre-6.5 system. However, if the store media containing Large Files is restored on a pre-6.5 system, only Non-Lagre files will be restored. A pre-6.5 restore skips the large files with the following error:

"<file>.<group>.<account> NOT RESTORED: MEDIA RECORD HEADER BLOCK CORRUPTED/INVALID"
