Disk ARchiver command line questions



I've been reading the man pages, but command line stuff isn't my forte :(

I want to backup some data using DAR (Disk ARchive) and here's what I 
have so far:


arrakis ~ # 
arrakis ~ # 
arrakis ~ # ls -alh /mnt/VolGroup00/LogVol00/home/
total 24K
drwxr-xr-x  3 root root 4.0K Oct 17 01:55 .
drwxr-xr-x 24  500  500 4.0K Oct 16 22:47 ..
drwx------ 30  500  500 4.0K Oct 16 22:47 thufir
arrakis ~ # 
arrakis ~ # dar --create /mnt/VolGroup00/LogVol00/home/thufir/ --slice 
690M  --tree-format --beep --pause


 --------------------------------------------
 862 inode(s) saved
 with 0 hard link(s) recorded
 0 inode(s) changed at the moment of the backup
 0 inode(s) not saved (no inode/file change)
 0 inode(s) failed to save (filesystem error)
 0 inode(s) ignored (excluded by filters)
 0 inode(s) recorded as deleted from reference backup
 --------------------------------------------
 Total number of inode considered: 862
 --------------------------------------------
 EA saved for 0 inode(s)
 --------------------------------------------
arrakis ~ # 
arrakis ~ # ls -alh /mnt/VolGroup00/LogVol00/home/total 106M
drwxr-xr-x  3 root root 4.0K Oct 17 01:57 .
drwxr-xr-x 24  500  500 4.0K Oct 16 22:47 ..
drwx------ 30  500  500 4.0K Oct 16 22:47 thufir
-rw-r--r--  1 root root 106M Oct 17 01:57 thufir.1.dar
arrakis ~ # 
arrakis ~ # date
Wed Oct 17 01:58:01 PDT 2007
arrakis ~ # 


Starting with the least important questions and increasing in 
significance:


1.)  How can I change the command so the .dar files are named backup.
[n].dar instead of thufir.[n].dar?

2.)  As it stands, it's going to take 862 slices to backup this data 
without compression?  I asked for slices of 690M, why is it only showing 
as 106M for this particular slice?

3.)  Do I just burn thufir.1.dar to disc (CD-R) as a regular data disc 
using, for example, the builti-in nautilus burner?

4.)  How do I get DAR to generate the second slice?

I know that these questions are answered in the manual, and I've read the 
manual, but they still elude me.




thanks,

Thufir





ps:  what's good about DAR, you ask?


DIRECT ACCESS  	

	
even using compression dar has not to read the whole backup to extract 
one file. This way if you just want to restore one file from a huge 
backup, the process will be much faster than using tar.
