Restoring Stored Files
System and user directories and files are stored to tape as a routine
part of the system backup process. User files are also stored to tape so
they can be erased from disk storage.
It is not necessary to RESTORE files stored during a backup, since they
are not deleted by the process. More commonly, they are restored at the
request of a user who has deleted a file by mistake.
1. Replying to the Tape Request
When a person wants a file restored, they issue the RESTORE command which
sends a tape request to the system console.
The syntax of a tape request has the form:
?hh:mm/#Snn/pin/LDEV FOR "T" ON TAPE (NUM)?
Mount the tape identified by "T" (NUM) on a tape drive and set the drive
on line, then enter:
REPLY pin,ldev
The pin is the process identification number from the tape request and
ldev is the logical device number of the tape drive on which the tape was
mounted.
2. Restoring Files
The syntax for creating a file equation and restoring the files is:
FILE T;DEV=TAPE
RESTORE *T;filename
If you are restoring your own or system files, execute the FILE and
RESTORE commands yourself. If you have answered a user's tape request,
the user executes the FILE and RESTORE commands. You can RESTORE more
than one file at a time by specifying wildcards and by entering several
file names separated by commas (,).
