Chapter 5 Storing Files

This chapter contains complete information on how to use the STORE command to store files to backup media. STORE can be used to back up a single file, all user, system, and system directory files (that is, a full system backup), or any number of files in between.

The information in this chapter describes how to use the STORE command and its options to create backups that can be restored using the RESTORE command. The subjects are:

Use the STORE command, and optionally the FILE command, to store a file or set of files. A FILE command is used to assign a filename to a backup device. A STORE command names the files to store and the options to use.

The STORE command options for naming files let you name a single file, several files, or all the files on the system. The group of files to store is called a fileset. In addition to naming many kinds of filesets, you can name filesets to exclude from the backup.

Refer to Chapter 6,"STORE and TurboSTORE Options," for a description of each of the STORE options. For example, you can print a list of all files stored, purge disk files immediately after storing them to backup, or request progress messages that show the status of the STORE process on the console.

Additionally, the MPE/iX command, VSTORE, allows you to verify that the data written to backup using the STORE program is valid. Refer to Chapter 9, "When STORE is Complete," for a description of using VSTORE, and Chapter 11, "Restoring Files," for descriptions of the VSTORE options, which are essentially the same as the RESTORE options.

Files can be stored to a single backup device or to multiple backup devices in several configurations. You can also store files in interleave format. Use multiple backup devices and interleave format to increase performance when you have a large set of files to store, for example, when you are performing a full system backup.

See Chapter 3 for information on preparing backup devices.

	CAUTION: Do not use the STORE or RESTORE programs to transfer any of the files that originally came from your system load tape (SLT) from LDEV 1 to a disk other than LDEV 1. These files reside in the SYS account and can be displayed by entering the SHOW command in the SY configurator of the SYSGEN utility. Also, do not purge or put a lockword on these files. Finally, do not use any command other than SYSGEN to manage the files within a configuration group. These configuration files come as a set and individual files may not be moved between groups or systems. Such actions will make these system files inaccessible causing problems either immediately or at a later time.
