SDDATE(C)                                  UNIX System V



     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.

     Diagnostics
          bad  conversion     If  the  date   set   is   syntactically
          incorrect.
