Linux Raw Backup Commands

No Compression (Fastest, but most space):

To backup:
dd if=/dev/sdX of=/path/to/file.bin


To restore:
dd if=/path/to/file.bin of=/dev/sdX

--------------------------------------------

These offer the best (not fastest) compression on storage:

To Backup (Binary):
dd if=/dev/sdX | bzip2 > /media/ubuntu/backupDrive/BACKUP_FILENAME.bzip2

To Backup (Flat bzip):
tar cvfj BACKUP_FILENAME.tar.bzip2 /media/ubuntu/MYDATAS/


Extract (Binary):
bunzip2 -dc /media/ubuntu/backupDrive/BACKUP_FILENAME.bzip2 | dd of=/dev/sdX

Extract (Flat bzip):
tar jxf BACKUP_FILENAME.tar.bzip2
