Restoring Files
Restoring Files from a Disk File
NOTE Parallel RESTOREs can be performed only with tape sets that were created
with a parallel STORE parameter. A sequential RESTORE can be used with any
tape set.
Parallel RESTORE allocates every subset of the tape set (for example,
STORESET=(*T1),(*T2) creates two subsets) to distinct parallel devices or
device pools, and expects a volume belonging to the subset to be mounted on
its allocated device or device pool only.
When DIRECTORY option is used with RESTORESET, please restore the
directories first if they are not already on the system with "RESTORE
;;DIRECTORY" command before restoring the files with the RESTORESET
option
Restoring Files from a Disk File
You can restore files from a disk file created by TurboSTORE by specifying file equations
for the disk files. You can restore from parallel disk files by using the RESTORESET
parameter. Details on restoring files from disk files are covered in the following sections.
NOTE Restoring data from disk files created with TurboSTORE/iX 7x24
True-Online Backup is only supported on systems running MPE/iX Release
5.5 or higher. Although only the TurboSTORE/iX 7x24 True-Online Backup
product can create disk files, any version of STORE or TurboSTORE running
on MPE/iX 5.5 or later can restore data from disk files.
Specifying the Disk File
You direct RESTORE to restore files from a disk file created by TurboSTORE by using file
equations. These file equations follow the same rules that TurboSTORE used when it
created the disk files. You must specify the name of the disk file to be used in the file
equation, and specify the DEV=DISC option. All other options specified in the file equation
will be ignored. For example, to restore from the disk file MYBACKUP.BACKUPS.SYS,
issue the following file equation:
:FILE DISKF=MYBACKUP.BACKUPS.SYS;DEV=DISC
You can then use this file equation in your RESTORE command, just as you would use a file
equation for a tape device:
:RESTORE *DISKF;@.@.@;SHOW
You can change the name and location of the disk backup file from what it was when
STORE created it. You then specify their new name and/or location when issuing the file
equation. See the "Storing to Disk Files" section in Chapter 3, "Preparing Storage
Devices," for more information on the naming convention used by TurboSTORE when it
