finc(1M)                                                 finc(1M)



     NAME
          finc - fast incremental backup

     SYNOPSIS
          finc [-a n] [-c n] [-m n] [-n file] file-system raw-tape

     DESCRIPTION
          finc selectively copies the input file-system to the output
          raw-tape.  Mount the input file-system read-only to ensure
          an accurate backup, although you can obtain acceptable
          results in read-write mode.  The tape must be previously
          labelled by labelit (see volcopy(1M)).

          We recommend using the ff command to produce an index of the
          tape's contents before using finc.  You can recover files on
          a finc tape with the frec command.

          The argument n in the following options is 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
          24 hours.

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

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

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

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

     EXAMPLE
               finc -m -2 /dev/rdiskusr /dev/rmt/0m

          writes a tape of all files from the /usr file-system
          modified in the last 48 hours.  /bin/finc
