finc(8)                             CLIX                             finc(8)



  NAME

    finc - Carries out fast incremental backup

  SYNOPSIS

    /etc/finc [flag ... ] file-system raw-tape

  FLAGS

    -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 inode has been changed in n days.

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

  DESCRIPTION

    The finc command selectively copies the input of the file-system to the
    output raw-tape.  The cautious user will want to mount the input file-
    system in a read-only mode to insure an accurate backup, although
    acceptable results can also be obtained in the read-write mode.  The tape
    must be previously labeled by labelit.  The selection is controlled by the
    flags, 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 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 24 hours.

  EXAMPLES

    1.  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


    2.  To write a tape of all files on the /usr file system newer than
        backupfile:

        finc -n backup /dec/rdsk/s)u)p.7.3 /dev/rSA/ctape1

    /dev/rdsk*   Raw device files.

  NOTES

    The finc command does not work with Fast File Systems (FFS).

  CAUTIONS

    The file system being backed up should not be mounted read-write.

  DIAGNOSTICS

    No selection criteria
           No files were written to tape because no file selection criteria
           flags had been given.

    Input device is nonexistent or not a raw device
           The device given does not exist, or the device is not a raw
           (character special) device.

  EXIT VALUES

    1   An error occurred and the backup could not be completed.

    0   Successful backup tape made.
