21
22 Add "-c backup"

27
28 Not sure, am guessing it's not going through the directory tree.

32
33 I would suggest writing the *.dar files to disc (CD-R) in the same way as
34 how you'd write normal datafiles.
35 Eg. do NOT treat the *.dar files as ISO-images. Strange things can happen
36 this way.

38 > 4.) How do I get DAR to generate the second slice?
39
40 Not entirely sure, but the following command works for me:
41
42 dar -m 256 -y -s 690M -D -R /mnt/VolGroup00/LogVol00/home/thufir/ -c
43 thufir -Z "*.zip" -Z "*.gz" -Z "*.bz2" -Z "*.mp3" -Z "*.jpg"
44
45 You would probably want to add "--beep --pause" to it. The "-Z" options
46 are there to tell dar not to bother trying to compress already compressed
47 files. (makes it faster)

51
52 The manual has alot of examples, I got it working for me by taking the
53 examples and then editing it to suit my needs, rather then trying to build
54 the command myself.
55
56 Also, the "--tree-format" option isn't in the man-page of dar on my system.
57
58 Kind regards,
