Tar differential backup
I am backing up some data to an NTFS formatted backup drive. I have to preserve the Unix permissions of the data being backed up and therfore use backup into a tar file.
I would like to backup the differnential data in the tar file similiar to how Rsync works so as to save on backup time as it currently takes a long time to do a full backup.
Can this be achieved using tar?
Thanks

svn-fast-backup
svn-fast-backup(1) General Commands Manual svn-fast-backup(1)
NAME
svn-fast-backup - very fast backup for Subversion fsfs repositories.
SYNOPSIS
svn-fast-backup [-q] [-k{N|all}] [-f] [-t] [-s] repos_path backup_dir
DESCRIPTION
svn-fast-backup uses rsync snapshots for very fast backup of a Subversion fsfs repository at repos_path to backup_dir/repos-rev, the latest
revision number in the repository. Multiple fsfs backups share data via hardlinks, so old backups are almost free, since a newer revision
of a repository is almost a complete superset of an older revision.
This is good for replacing incremental log-dump+restore-style backups because it is just as space-conserving and even faster; there is no
inter-backup state (old backups are essentially caches); each backup directory is self-contained. It has the same command-line interface
as svn-hot-backup(1) (if you use --force), but only works for fsfs repositories.
svn-fast-backup keeps 64 backups by default and deletes backups older than these; this can be adjusted with the -k option.
OPTIONS
-h, --help
Shows some brief help text.
-q, --quiet
Quieter-than-usual operation.
-k, --keep=N
Keep a specified number of backups; the default is to keep 64.
-k, --keep=all
Do not delete any old backups at all.
-f, --force
Make a new backup even if one with the current revision exists.
-t, --trace
Show actions.
-s, --simulate
Don't perform actions.
