Backup/restore hard drive using dd tool
I try to make copy (backup) my hard drive with OS (linux). I did it in the following way:
dd if=/dev/sda conv=sync,noerror bs=64K | gzip -c > /mnt/fs/sda.img.gz
where I mounted file share under /mnt/fs.
Then I want restore my copy:
gunzip -c /mnt/fs/sda.img.gz | dd of=/dev/sdc conv=sync,noerror bs=64K
and my OS is crashed.. (not working..)
I want to mark - I made the copy from working OS. My hard drive was detected as sda. Restore the copy I made from linux-liveCD and there my hard drive was mounted as sdc. It could be a problem?
