finc(1M)                (Cartridge Tape Utilities)                 finc(1M)


   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 system and
         the tape to finc.  Failure to do so will cause an error.
