将 块设备 压缩至 文件 To save space, you can compress data produced by dd with gzip, e.g.:dd if/dev/hdb | gzip -c /image.img.gz
You can restore your disk with:gunzip -c /image.img.gz | dd of/dev/hdb
To save even more space, defragment the drive/partition you wish to clone beforehand (if appropriate), then zero-out all the remaining unused space, making it easier for gzip to compress:mkdir /mnt/hdb
mount /dev/hdb /mnt/hdb
dd if/dev/zero of/mnt/hdb/zero
Wait a bit, dd will eventually fail with a disk full message, then:rm /mnt/hdb/zero
umount /mnt/hdb
dd if/dev/hdb | gzip -c /image.img.gz
Also, you can get a dd process running in the background to report status by sending it a signal with the kill command, e.g.:dd if/dev/hdb of/image.img
kill -SIGUSR1 1234
Check your system - the above command is for Linux, OSX and BSD dd commands differ in the signals they accept (OSX uses SIGINFO - you can press CtrlT to report the status). dd if/dev/hdb of/dev/sda
