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 |
10 |
have so far: |

|
12 |
arrakis ~ # |

arrakis ~ # |
14 |
arrakis ~ # ls -alh /mnt/VolGroup00/LogVol00/home/ |

Starting with the least important questions and increasing in |
48 |
significance: |
49 |
|
50 |
1.) How can I change the command so the .dar files are named backup. |
51 |
[n].dar instead of thufir.[n].dar? |
52 |
|
53 |
2.) As it stands, it's going to take 862 slices to backup this data |
54 |
without compression? I asked for slices of 690M, why is it only showing |
55 |
as 106M for this particular slice? |
56 |
|
57 |
3.) Do I just burn thufir.1.dar to disc (CD-R) as a regular data disc |
58 |
using, for example, the builti-in nautilus burner? |
59 |
|
60 |
4.) How do I get DAR to generate the second slice? |
61 |
|
62 |
I know that these questions are answered in the manual, and I've read the |
63 |
manual, but they still elude me. |
64 |

thanks, |

ps: what's good about DAR, you ask? |
70 |
|
71 |
DIRECT ACCESS |
72 |
|
73 |
|
74 |
even using compression dar has not to read the whole backup to extract |
75 |
one file. This way if you just want to restore one file from a huge |
76 |
backup, the process will be much faster than using tar. |
