Disk Restore from Tape

(A1) To restore selected files or folders from tape (VMS)

     (1) Log-in as System and create a folder to hold the restored files.
         Ideally, this folder name should mirror the folder that is to
         be restored. For example:

           $ create/dir mvfd4:[jane]/owner=jane/vers=5

     (2) Insert the proper backup tape into the DAT tape drive (on MVF),
         and mount it:

           $ mount/for mka500:

     (3) Start the restore of all files for [jane...] as follows:

           $ backup mka500:*.*/select=[jane...]*.*;*/save mvfd4:[*]/log

         This should restore all files and sub-folders within [jane] while
         maintaining the directory tree structure.

(A2) How to restore an entire disk from tape (VMS)

    Note: This procedure is required very rarely, in case of a disk crash
    where an entire disk has been lost, e.g.  This procedure will
    completely erase the previous contents of the disk, so use with
    extreme caution.

     This should be used only when an _entire_ disk needs to be restored.
     (the example below assumes we are restoring one of the VFF disks)

     (a) Install replacement disk with proper scsi ID, termination etc.

     (b) Reboot computer.

     (c) Insert tape to be restored into tape drive.

         At present, tape drive is on MVF, device MKA500:

         Let us assume that the disk to be restored is connected to VS
         with scsi ID 2, i.e. disk is VS$DKA200:

     (d) Log-in on MVF as system.

     (e) $ alloc vs$dka200:
         $ init vs$dka200: vffdisk2      (e.g. - label of disk being restored)
         $ mount vs$dka200: vffdisk2
         $ mount/for mka500:
         $ backup mka500:*.*/save vs$dka200:[*]/log
           ... should take 30 to 180 minutes ...
         $ dism mka500:

     (f) Make sure files were restored OK on VS$DKA200:

     (g) Check file ownership etc. on VS$DKA200: (i.e. $ dir/full etc.)

     (h) $ dism vs$dka200:
         $ dealloc vs$dka200: 

     (i) Shut down VS, remove the newly restored disk, set SCSI ID
         properly, and install it in VFF (or wherever it belongs).
