Do incremental backup without tar files up
I'm trying to do a incremental backup for a big NFS. Since space is not an issue, I don't want to compress them or end up with a big tarball for full backup( and a series of small tarballs for incremental backup). Basically I want the TAR backup/restore functionality but not TAR files up.
Requirements:
1. files/directories are transferred directly so that I can browse through the backup easily.
2. Have a snapshot file that can be used to do incremental backup. (like the one Tar generates, which used to keep track of changes)
Any suggestions? Thanks!
Note: Rsync is not an option, because target filesystem is not unix-like. It only supports GET/LIST/PUT.

shtool-tarball
SHTOOL-TARBALL.TMP(1) GNU Portable Shell Tool SHTOOL-TARBALL.TMP(1)
NAME
shtool-tarball - GNU shtool command for rolling standardized tarballs
SYNOPSIS
shtool tarball [-t|--trace] [-v|--verbose] [-o|--output tarball] [-c|--compress prog] [-d|--directory directory] [-u|--user user]
[-g|--group group] [-e|--exclude pattern] path [path ...]
DESCRIPTION
This command is for rolling input files under path into a distribution tarballs which can be extracted by tar(1).
The four important aspects of good open source software tarballs are: (1) unpack into a single top-level directory, (2) top-level directory
corresponds to the tarball filename, (3) tarball files should be sorted and (4) arbitrary names for file owner and group.
OPTIONS
The following command line options are available.
-v, --verbose
Display some processing information.
-t, --trace
Enable the output of the essential shell commands which are executed.
-o, --output tarball
Output tarball to file tarball.
-c, --compress prog
Pipe resulting tarball through compression program prog.
-d, --directory directory
Sets the top-level directory into which the tarball unpacks. By default it is tarball without the trailing ".tar.*" extension.
-u, --user user
The user (owner) of files and directories in the tarball to user.
-g, --group group
The group of files and directories in the tarball to group.
-e, --exclude pattern
Exclude files and directories matching comma-separated list of regex pattern from the tarball. Directories are expanded before the
filtering takes place. The default filter pattern is ""CVS,\.cvsignore,\.svn,\.[oa]$"".
EXAMPLE
# Makefile.in
dist:
...
V=`shtool version -d short ...`;
shtool tarball -o foobar-$$V.tar.gz -c 'gzip -9'
-u bar -g gnu -e 'CVS,.cvsignore' .
HISTORY
The GNU shtool tarball command was originally written by Ralf S. Engelschall <rse@engelschall.com> in 1999 for GNU shtool.
