how long should it take to backup 100gb?
 

Hi all :)
Using dd it takes about 25 hours to copy from a 100gb drive to a 100 usb drive. Is that right? I tried Clonezilla and that takes around 6 hours. Is there any other live cds that backup/clone faster? I have been using acronis and that takes around 2 hours 100gb hhd to 100gb usb. I am looking for something Live and around 2 hours if possible.
Bckspc :)

What parameters are you using for dd? Setting bs is a key speed parameter, and playing with different values should give you a good idea of the optimum.

hi billymayday
bs=9728
is there a app to see the output/speed/time of dd?

Where did 9728 come from?

I've simple run tests before using

time dd if=foo of=bar bs=whatever

for different values of bs with a testfile of reasonable size.

I am only new to linux so got the command line off a fourm is it wrong? what do you use?

Really depends on your machine. Read the first post or two of this http://www.linuxquestions.org/questi...ommand-362506/ to get some ideas.

Here are a couple of examples for you:
