tar is used to create or extract an archives, a tar files always have .tar extension. you can extract from an archive tar file by
issuing tar xvf my_file.tar
and
you can create tar file by issuing
tar cvf my_newfile.tar archive_this_file
while ufsdump is used to backup all files or whole filesystem to a tape or another filesystem.
you use ufsdump to create a full backup or an incremental backup
to use ufsdump to create a full backup issue
ufsdump ucf 0 /dev/rmt/0 /usr
this will do a full backup of the /usr filesystem.
An incremental backup, back's up modify file only while differential is just another type of incremental backup.

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.
