FINC(1M) (Cartridge Tape Utilities) FINC(1M)
NAME
finc - fast incremental backup
SYNOPSIS
/etc/finc [-an] [-mn] [-cn] [-nfile] 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 insure an accurate backup, although
acceptable results can be obtained in read-write mode. The
tape must be previously labeled by labelit. The selection
is controlled by the options, 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 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:
