Eterm # tar --help
GNU `tar' saves many files together into a single tape or disk archive, and
can restore individual files from the archive.
Usage: tar [OPTION]... [FILE]...
Examples:
tar -cf archive.tar foo bar # Create archive.tar from files foo and bar.
tar -tvf archive.tar # List all files in archive.tar verbosely.
tar -xf archive.tar # Extract all files from archive.tar.
If a long option shows an argument as mandatory, then it is mandatory
for the equivalent short option also. Similarly for optional arguments.
주요 동작 모드:
-t, --list 아카이브의 내용물을 출력합니다
-x, --extract, --get 아카이브에서 파일을 추출합니다
-c, --create 새로운 아카이브를 만듭니다
-d, --diff, --compare 아카이브와 파일 시스템간의 차이점을 비교합니다
-r, --append 아카이브 끝에 파일을 추가합니다
-u, --update 아카이브 안의 것보다 새로운 파일만 추가합니다
-A, --catenate 아카이브에 tar 파일을 추가합니다
--concatenate -A와 같음
--delete 아카이브로부터 제거합니다 (자기 테이프에선 안됨!)
Operation modifiers:
-W, --verify attempt to verify the archive after writing it
--remove-files remove files after adding them to the archive
-k, --keep-old-files don't replace existing files when extracting
--overwrite overwrite existing files when extracting
--no-overwrite-dir preserve metadata of existing directories
-U, --unlink-first remove each file prior to extracting over it
--recursive-unlink empty hierarchies prior to extracting directory
-S, --sparse handle sparse files efficiently
-O, --to-stdout extract files to standard output
-G, --incremental handle old GNU-format incremental backup
-g, --listed-incremental=FILE
handle new GNU-format incremental backup
--ignore-failed-read do not exit with nonzero on unreadable files
--occurrence[=NUM] process only the NUMth occurrence of each file in
the archive. This option is valid only in
conjunction with one of the subcommands --delete,
--diff, --extract or --list and when a list of
files is given either on the command line or
via -T option.
NUM defaults to 1.
Handling of file attributes:
--owner=NAME force NAME as owner for added files
--group=NAME force NAME as group for added files
--mode=CHANGES force (symbolic) mode CHANGES for added files
--atime-preserve don't change access times on dumped files
-m, --modification-time don't extract file modified time
--same-owner try extracting files with the same ownership
--no-same-owner extract files as yourself
--numeric-owner always use numbers for user/group names
-p, --same-permissions extract permissions information
--no-same-permissions do not extract permissions information
--preserve-permissions same as -p
-s, --same-order sort names to extract to match archive
--preserve-order same as -s
--preserve same as both -p and -s
장치 선택과 전환:
-f, --file=ARCHIVE 아카이브 파일 또는 ARCHIVE 장치를 사용합니다
--force-local 이름에 콜론이 있는 아카이브 파일도 지역 파일로
인식합니다
--rsh-command=COMMAND rsh 대신 원격 COMMAND를 사용합니다
-[0-7][lmh] 드라이브와 기록 밀도를 지정합니다
-M, --multi-volume 다중 볼륨 아카이브를 생성/출력/추출합니다
-L, --tape-length=NUM NUM x 1024 바이트를 쓴 뒤에 테이프를 바꿉니다
-F, --info-script=FILE 각 테이프의 끝에서 스크립트를 실행합니다
(-M을 포함함)
--new-volume-script=FILE -F FILE과 같음
--volno-file=FILE FILE 안에 있는 볼륨 번호를 사용/갱신합니다
장치 블럭 설정:
-b, --blocking-factor=BLOCK 레코드당 BLOCK x 512 바이트
--record-size=SIZE 레코드당 SIZE 바이트, 512의 배수
-i, --ignore-zeros 아카이브에서 영으로 된 블럭을 무시합니다
(EOF를 의미함)
-B, --read-full-records 읽은 것을 재블럭화합니다 (4.2BSD 파이프용으로)
Archive format selection:
--format=FMTNAME create archive of the given format.
FMTNAME is one of the following:
v7 old V7 tar format
oldgnu GNU format as per tar <= 1.12
ustar POSIX 1003.1-1988 (ustar) format
posix POSIX 1003.1-2001 (pax) format
gnu GNU format
--old-archive, --portability same as --format=v7
--posix same as --format=posix
-V, --label=NAME create archive with volume name NAME
PATTERN at list/extract time, a globbing PATTERN
-j, --bzip2 filter the archive through bzip2
-z, --gzip, --ungzip filter the archive through gzip
-Z, --compress, --uncompress filter the archive through compress
--use-compress-program=PROG filter through PROG (must accept -d)
Local file selection:
-C, --directory=DIR change to directory DIR
-T, --files-from=NAME get names to extract or create from file NAME
--null -T reads null-terminated names, disable -C
--exclude=PATTERN exclude files, given as a PATTERN
-X, --exclude-from=FILE exclude patterns listed in FILE
--anchored exclude patterns match file name start (default)
--no-anchored exclude patterns match after any /
--ignore-case exclusion ignores case
--no-ignore-case exclusion is case sensitive (default)
--wildcards exclude patterns use wildcards (default)
--no-wildcards exclude patterns are plain strings
--wildcards-match-slash exclude pattern wildcards match '/' (default)
--no-wildcards-match-slash exclude pattern wildcards do not match '/'
-P, --absolute-names don't strip leading `/'s from file names
-h, --dereference dump instead the files symlinks point to
--no-recursion avoid descending automatically in directories
-l, --one-file-system stay in local file system when creating archive
-K, --starting-file=NAME begin at file NAME in the archive
--strip-path=NUM strip NUM leading components from file names
before extraction
-N, --newer=DATE-OR-FILE only store files newer than DATE-OR-FILE
--newer-mtime=DATE compare date and time when data changed only
--after-date=DATE same as -N
--backup[=CONTROL] backup before removal, choose version control
--suffix=SUFFIX backup before removal, override usual suffix
Informative output:
--help print this help, then exit
--version print tar program version number, then exit
-v, --verbose verbosely list files processed
--checkpoint print directory names while reading the archive
--check-links print a message if not all links are dumped
--totals print total bytes written while creating archive
--index-file=FILE send verbose output to FILE
-R, --block-number show block number within archive with each message
-w, --interactive ask for confirmation for every action
--confirmation same as -w
Compatibility options:
-o when creating, same as --old-archive
when extracting, same as --no-same-owner
The backup suffix is `~', unless set with --suffix or SIMPLE_BACKUP_SUFFIX.
The version control may be set with --backup or VERSION_CONTROL, values are:
t, numbered make numbered backups
nil, existing numbered if numbered backups exist, simple otherwise
never, simple always make simple backups
ARCHIVE may be FILE, HOST:FILE or USER@HOST:FILE; DATE may be a textual date
or a file name starting with `/' or `.', in which case the file's date is used.
*This* `tar' defaults to `--format=gnu -f- -b20'.

-G, --incremental
증분이 뭘까 찾아보다가 발견한 것이지만...
왜 그렇게 어려운 단어를 선택해서 번역을 해놓았는지 찾기도 힘들고 이해하기도 힘들고...
찾다보니 나오던데 tar는 사실 incremental backup 기능이 미약하다고 하더군요.
Sun에서는 ufsdump라는 것을 지원해주던데... 그것과 비슷한 것을 한번 찾아보세요.

좋은 하루 되세요.
