NAME
     finc - fast incremental backup

SYNOPSIS
     /usr/sbin/finc [selection-criteria] file-system raw-tape

DESCRIPTION
     finc selectively copies the input file-system to the  output
     raw-tape.   The  cautious will want to mount the input file-
     system read-only to  ensure  an  accurate  backup,  although
     acceptable  results can be obtained in read-write mode.  The
     tape must be previously labelled by labelit.  The  selection
     is  controlled  by  the  selection-criteria,  accepting only
     those inodes/files for whom the conditions are true.

     It is recommended that production of a finc tape be preceded
     by the ff command, and the output of ff be saved as an index
     of the tape's  contents.   Files  on  a  finc  tape  may  be
     recovered with the frec command.

     The argument n in the  selection-criteria  which  follow  is
     used  as  a  decimal  integer  (optionally signed), where +n
     means more than n, -n means less than n, and n means exactly
     n.  A day is defined as a period of 24 hours.

     -a n            True if the file  has  been  accessed  in  n
                     days.

     -m n            True if the file  has  been  modified  in  n
                     days.

     -c n            True if the i-node has  been  changed  in  n
                     days.

     -n file         True for any file which  has  been  modified
                     more recently than the argument file.

EXAMPLES
     To write a tape consisting of  all  files  from  file-system
     /usr modified in the last 48 hours:
          finc  -m  -2  /dev/rdsk/c1d0s2  /dev/rSA/ctape1

NOTE
     The raw device is required when providing both the file sys-
     tem  and  the  tape to finc.  Failure to do so will cause an
     error.
