Restoring Files
Restoring Files from a Disk File
creates disk backup files.
Restoring From Multiple Disk Files
If the backup to be restored contains more than one disk file, create only one file equation
pointing to the
first disk file. RESTORE will automatically open the subsequent disk
files. Do not create any file equations for the other disk files.
Be sure that all of the disk files in a backup are present at the time of the backup.
RESTORE will abort with an error if it is unable to open a disk file that is part of the
backup.
All of the disk files for the backup must reside in the same group or HFS directory.
RESTORE will use the fully qualified path for the file specified with the file equation to
determine where the other disk files are located.
If you want to rename the disk files or change their location from where STORE originally
created them, be sure that all disk files are put in the new location. Also, the
base filename
(i.e., without the ".#" extension), must all remain the same. RESTORE cannot locate disk
files that are part of the same backup if they have different base filenames.
Restoring from Parallel Disk Files
If the backup was created by writing to multiple, parallel disk files with the the STORESET
parameter, then files from that backup can be restored with the RESTORESET parameter.
For each parallel disk file to be restored, a file equation must be issued for the first disk file
in each parallel set.
For example, to restore from a two-way parallel disk backup, specify the following file
equations:
:FILE SET1=FULL1.BACKUPS.SYS;DEV=DISC
:FILE SET2=FULL2.BACKUPS.SYS:DEV=DISC
These file equations can then be used with the RESTORESET parameter:
:RESTORE ;@.@.SYS;SHOW;RESTORESET=(*SET1),(*SET2)
As when restoring from multiple disk files, the base names of all disk files in each parallel
set must be the same, and all files of a parallel set must reside in the same group or HFS
directory. However, the names can be changed from what they were when they were
created by TurboSTORE.
Unlike restoring from tape devices, when performing a parallel restore, all parallel sets in
the backup must be specified in the RESTORESET command. Tape devices can use console
messages to request that media from an additional parallel backup be mounted. However,
when restoring from disk backups, no operator messages are issued, and if a parallel set
was not specified in the RESTORE command, RESTORE will fail to restore all files on the
missing parallel sets, and will abort. Always specify all parallel sets in the RESTORESET
parameter.
NOTE Just as storing to serial disk files with the STORESET command is not allowed
