There are various programs that can help with doing disk/partition images. 
I've been the maintainer of the G4L project since about 2004. It basically 
uses dd with compression options to make image files on network or local 
devices. It also includes ntfsclone and fsarchiver to make file level images.
Since dd is used for most options, and does a full backup of all sectors, it is 
best to clear all unused sectors before doing a backup, and options to do that 
are included. Takes a longer than file level, but you then have a bit level 
backup of system, so issues of not only file data is insured, but all other 
security and links are also. Have program as part of my grub boot menu to 
run, or let students automatically restore the 160G Windows 7 partition on 
machines. Keep a copy of the Windows and linux partions on partition 
/dev/sda8, and have it setup to restore the 30G image of Window 7 in about 
12 minutes. Putting the image on a 128G usb 3 flash, it can be restored in 
about 4 1/2 minutes. 

There are other programs like G4U, and Clonezilla and others, and there is 
always just using dd. 

Program is free and on sourceforge.
