SDDATE(C)                XENIX System V                 SDDATE(C)



     Name
          sddate - Prints and sets backup dates.

     Syntax
          sddate [ name lev date ]

     Description
          If no argument is given, the contents of the backup date
          file /etc/ddate are printed.  The backup date file is
          maintained by backup(C) and contains the date of the most
          recent backup for each backup level for each filesystem.

          If arguments are given, an entry is replaced or made in
          /etc/ddate. name is the last component of the device
          pathname, lev is the backup level number (from 0 to 9), and
          date is a time in the form taken by date(C):

               mmddhhmm[yy]

          Where the first mm is a two-digit month in the range 01-12,
          dd is a two-digit day of the month, hh is a two-digit
          military hour from 00-23, and the final mm is a two-digit
          minute from 00-59.  An optional two-digit year, yy, is
          presumed to be an offset from the year 1900, i.e., 19yy.

          Some sites may wish to back up file systems by copying them
          verbatim to backup media.  sddate could be used to make a
          ``level 0'' entry in /etc/ddate, which would then allow
          incremental backups.

          For example:

               sddate rhd0 5 10081520

          makes an /etc/ddate entry showing a level 5 backup of
          /dev/rhd0 on October 8, at 3:20 PM.

     Files
          /etc/ddate
