Hello,
I have a disk image of about 8.4G that I took from a friends computer about 18 months ago. Since then the harddrive has been reformatted and that data lost.
I would like to send disk image via CD's to the UK where the disk image can be reassembled. I imagine that might take about 12-13 CD's
the file is recognised as a xxxxxx.dat file and I am sure I made it using something like
dd if=/dev/hda5 of=/mnt/hdb11/image_name.dat
Would people be prepared to offer any hints on how to do that?
Cheers
Chris, Basically the easiest way is to split into chunks that are smaller than CD size. Then you put them on CDs. At the other end you can put them back together using the cat command like: cat chunk1 chunk2 chunk3 > bigfile As for splitting I see there is a split command in Debian and probably and others. Do "man split" to get more help. I haven't tested this. I also googled and found this: http://www.bluehaze.com.au/unix/cdbkup.html that fsplit does splitting for backups. I would definitely test on some binary files to check this all works though. Try chopping up a JPEG photo or similar and test reassembly. There probably is a program out there to make this all easy but I don't know what it is!
