Partition Image is a Linux/UNIX utility which saves partitions in many formats (see below) to an image file. The image file can be compressed in the GZIP/BZIP2 formats to save disk space, and split into multiple files to be copied on removable floppies (ZIP for example), ... Partitions can be saved across the network since version 0.6.0.

Partition Image will only copy data from the used portions of the partition. For speed and efficiency, free blocks are not written to the image file. This is unlike the 'dd' command, which also copies empty blocks. Partition Image also works for large, very full partitions. For example, a full 1 GB partition can be compressed with gzip down to 400MB.

I use this on all my Windows boxes, Slackware Linux boxes. I've never had to use it yet with the *BSD machines.
You can use this to save your partition to an image file, even across the nework, which means your machine you plan to back up to must be running the partimaged server.
Then load this partimage Live-CD, and add the necessary IP info to the box after booting, which is usually just adding IP/subnet and gateway info (if needed).
Select the partition to backup, set options, and connect to the ip address of the server box.
It should only take a few minutes to copy the partition across the network. then you can resize the partition, and restore from the image.
Which would require booting once more on the Live-CD, adding the ip/subnet info, selecting the partition to restore, and the ip of the server and the directory where the partition was saved.

You will also need to download the program to install on the server box. Or run both boxes from the CD (not tested by myself.)

Also. you can just back up to a seperate partition on the same machine if you do not have a second box. if you have enough space on the Windows Partition, just backup to that drive.
It saves the backup as a image file.

I've been using this sucessfully for a few years now.

Look on the site for more info. This program works well.

Also contained on the Live-CD is a partition resizing tool. qt_parted which might be something you can use too, just to adjust the size of the partition without the image creation steps, which is really just used when backing up data. It is just like PowerQuests Partition Magic, except that PM costs and pated is free, Both tools are free.

scrounge-ntfs

scrounge-ntfs(8)					    BSD System Manager's Manual 					  scrounge-ntfs(8)

NAME

     scrounge-ntfs -- helps retrieve data from corrupted NTFS partitions

SYNOPSIS

     scrounge-ntfs -l disk
     scrounge-ntfs -s disk
     scrounge-ntfs [-m mftoffset] [-c clustersize] [-o outdir] disk start end

DESCRIPTION

     scrounge-ntfs is a utility that can rescue data from corrupted NTFS partitions. It writes the files retrieved to another working file system.
     Certain information about the partition needs to be known in advance.

     The -l mode is meant to be run in advance of the data corruption, with the output stored away in a file. This allows scrounge-ntfs to recover
     data reliably. See the 'NOTES' section below for recover info when this isn't the case.

OPTIONS

     The options are as follows:

     -c 	 The cluster size (in sectors). When not specified a default of 8 is used.

     -l 	 List partition information for a drive. This will only work when the partition table for the given drive is intact.

     -m 	 When recovering data this specifies the location of the MFT from the beginning of the partition (in sectors). If not specified
		 then no directory information can be used, that is, all rescued files will be written to the same directory.

     -o 	 Directory to put rescued files in. If not specified then files will be placed in the current directory.

     -s 	 Search disk for partition information. (Not implemented yet).

     disk	 The raw device used to access the disk which contains the NTFS partition to rescue files from. eg: '/dev/hdc'

     start	 The beginning of the NTFS partition (in sectors).

     end	 The end of the NTFS partition (in sectors)

NOTES

     If you plan on using this program sucessfully you should prepare in advance by storing a copy of the partition information. Use the -l option
     to do this. Eventually searching for disk partition information will be implemented, which will solve this problem.

     When only one partition exists on a disk or you want to rescue the first partition there are ways to guess at the sector sizes and MFT loca-
     tion. See the scrounge-ntfs web page for more info:
