Full Discussion: Do incremental backup without tar files up

Tools 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.

BARRYBACKUP(1)						      General Commands Manual						    BARRYBACKUP(1)

NAME

       barrybackup - Barry Project's backup program for the BlackBerry handheld

SYNOPSIS

       barrybackup [-?][-d]

DESCRIPTION

       barrybackup is a GUI application for backing up and restoring Blackberry handheld databases.

       The  application  allows for filtering of databases for both backup and restore, so not all databases need to be backed up at once, nor all
       restored.

       Backups and configuration files are stored by default in the user's home directory, under ~/.barry/backup/PIN.	This  destination  can	be
       changed in the config dialogs, per device.

       The backup files are compressed tarballs containing specially named files for each record of the databases.

OPTIONS

       -d     --debug-output Enables low level protocol debug output written to stdout/stderr.

       --display=DISPLAY
	      Specify which X display to use.

       -?     --help Show summary of options.

       -h, --help
	      Show summary of options.

TAR FORMAT

       Backups are stored in tar format, compressed with gzip.	Backup files are named with the following pattern:

	    PIN-YYYYMMDD-HHMMSS[-tag_name].tar.gz

       The tag name is optional and is used to name a particular backup.

       Each record is appended to the tar file using the following pattern for the filename:

	    DBname/RecordID RecordTypeID

       That is, the database name is used as the directory name, and the filename contains the record ID and record type ID separated by a space.

       Database names can contain spaces.

       Record  IDs  are generally unique, but not all Blackberry devices mandate this, so it is possible, but rare, to have two records in the tar
       file with the same filename.  This is ok.  The only problem you'd see is if you expanded such a tar file  to  a	filesystem.   The  restore
       process just reads in the filename sequentially and writes them to the device, so duplicate record IDs are not a problem.
