Archive and Backup



ACREATE2

%externalintegerfn ACREATE2(%string(18)INDEX, TAPE, %string(8)FDATE,
      %string(11)FILE, %integer FSYS, NKB, CHAPTER, TYPE)

 This procedure is provided for use by the archive program.  A new
 archive index entry is created for USER, giving TAPE, CHAPTER and
 no-of-Kbytes attributes to be associated with FILE.  (Access permission
 attributes are given to FILE by separate calls of DPERMISSION.)

 DATE should normally be left null, when the current date will be used.


DMODARCH

%externalintegerfn DMOD ARCH(%string(18)FILE INDEX, %string(11)FILE,
      %string(8)DATE, %record(AINFF)%name ENT,
      %integer FSYS, TYPE)

 This procedure is provided for the System Manager to make amendments to
 archive index entries.  FILE INDEX, FILE, DATE and FSYS determine the
 entry to be modified.  Record ENT has the same format as that supplied
 by DFILENAMES (TYPE=1).  Fields (other than NAME) which differ from
 those of the specified index entry will be used to update the entry.
 Bits in TYPE as for 'ADESTROY'.


DNEWARCHINDEX

%externalintegerfn DNEW ARCH INDEX(%string(18)FILE INDEX,
      %integer FSYS, KBYTES)

 This privileged procedure creates a new archive index of KBYTES Kbytes
 for file index FILE INDEX on disc FSYS.  The minimum size allowed is 4
 Kbytes, allowing about 80 archive files to be described.


DRESTORE

%externalintegerfn DRESTORE(%string(19)FILE INDEX, %string(255)FILE,
      %string(8)ADATE, %integer FSYS, TYPE)

 This procedure passes a restore request (if FILE exists on archive
 storage and is permitted to the caller) to VOLUMS.  ADATE may be left
 null, when the most recently archived copy of FILE will be restored.
 The file is restored into the file owner's index FILE INDEX.  TYPE
 is currently ignored and should be set to zero.


DRETRIEVE

%externalintegerfn DRETRIEVE(%string(6)TAPE, %integer CHAPTER)

 Provides an interface to VOLUMS for users to restore files which they
 have written to tape themselves.
