HD Install :: to dd or not to dd

well i figure 2.5 hrs should have been enough time to bzip2 a 971MB partition, but it is still sitting there with 100% cpu usage and 50% swap used.

i don't think it is working...

robh,

I suspect you will need to do the following.  

Boot from livecd
sudo mount <your external hdd> <mount Point>
cd <mount point>
bzip2 -1c < /dev/hda > myhdimage.img.bz2

thats it, i've had it with backing up my install. i think i'm gonna just fly solo and damn the consequences.

thanks for your slightly more verbose help brianw, but it seems that i'm not yet understanding the syntax/code enough to perform this task. i followed your above advice and the cpu has been maxed out for an hour now, with no sign of my compressed drive image coming out the other end.

i can wipe this 3.2 GB drive with all zeros in about 10 mins, so i reckon that an hour should be plenty of time to wait.

SaidinUnleashed described this as the "most efficient way" of imaging, but i'm on day 3 of trying now and still no luck. The man page for bzip2 is as dry and uninformative to a newbie, who is trying to learn the concepts of linux, as ~J.P.'s advice. Sorry J.P. but i want to know what the command is doing and what the operands are doing to further understand. i tried the one liner that you gave me to no avail, maybe i'm just not up to the skill level required for using linux.

ah well...
