I have added a 2 extra formats in latest version : VHD/VHDX and LZ4.

VHD/VHDX is using MS virtual disk API and LZ4 is using opensource LZ4 library.

While at it, I also added extra WIM compression methods (LZX and LZMS).

 

LZ4 is quite interesting as in some cases it is faster to compress thru LZ4 compared to using a RAW format and this despite the CPU overhead.

LZ4 files generated by Clonedisk are compatible with LZ4.exe.

Following some notes around netcat here and here.

Some extra commands to backup a disk over the network :

-listen on port 9000 and dump the raw file
nc -v -l -p 9000 > dump.img
(restore with nc -v -l -p 9000 < dump.img)

-same but compressed with lz4 via stdin
nc -v -l -p 9000 | lz4.exe -1 stdin -f dump.lz4
(restore with lz4 -l -c dump.lz4 | nc -v -l -p 9000
and not with nc -v -l -p 9000 -e « lz4.exe -c dump.lz4 »)

-the same but with 7zip
nc -v -l -p 9000 | 7z a dump.7z -si
(restore with 7z e dump.7z -so | nc -v -l -p 9000)

-the same but with bzip2
nc -v -l -p 9000 | bzip2 -z > dump.gz
(restore with bzip2 -cd < dump.gz | nc -v -l -p 9000)

 

lz4 can be downloaded here.
bzip2 can be downloaded here.
7-zip can be downloaded here.
netcat can be downloaded here.

You have this volume you want to backup but this is a live volume : some apps are constantly writting to it and you need to backup a snapshot.

Lets use CloneDisk and VSCSC

On the command line :
-Lets create a shadow volume copy : vscsc.exe -wait f:
In CloneDisk :
-lets assign a x: logical drive letter to our shadow volume copy (step 1 below) -> this step is optional
-lets backup this x: logical drive, or dosdevice if you did not assign a letter, to a file (step 2 below)

You can now restore from this file but also open it in 7zip, mount it with imdisk, etc.

Lately I have discovered libnfs.
I quote « LIBNFS is a client library for accessing NFS shares over a network. ».

It is well documented and easy to use with Delphi (or freepascal).

I have decided to build a lightweight NFS client with simple features : discover, list directories, read & write files.

That could be handy at some point with either CloneDisk or TinyPXE Server.

Download here.
Discuss here.

MakeIso will create an ISO from a source folder.

Supports multi-boot iso : x86 and EFI.
Support ISO9660, UDF, Joliet or any combination of these 3 filesystems.
Supports isolinux (checksum will be taken care of).
Tested successfully with Grub4Dos.

Mkiso is native (no external dependencies), standalone, built in on windows builtin imapi2.

MkIso is also part of CloneDisk.

Questions, feedback, requests welcome here.

Download here.

Regards,
Erwan

Updated version following up on this article : added netcat support

Download from here

RAW can be :
-A logical drive in the form of \\.\X:
-A physical drive in the form of \\.\physicaldriveX
-A volume in the form of \\?\Volume{e26e7b15-122a-11e7-82bf-806e6f6e6963}
-A volume snapshot in the form of \\?\GLOBALROOT\Device\HarddiskVolumeShadowCopy1
-A disk image file in the form of c:\temp\disk.img

DEVIO or NETCAT will be IP:PORT (ex: 127.0.0.1:9000)

NETCAT command line:
Use nc to backup incoming datas to a file (i.e RAW to NETCAT) -> nc.exe -v -n -l -p 9000 > c:\temp\disk.img
Use nc to restore datas from a file (i.e NETCAT to RAW) -> nc -l -v -p 9000 < c:\temp\disk.img

DEVIO (RAW to DEVIO or DEVIO TO RAW) command line:
A logical drive -> devio 9000 \\.\X:
A physical drive -> devio 9000 \\.\PhysicalDriveX
A physical drive and a partition (starting a 1) -> devio 9000 \\.\PhysicalDriveX 2
A file (must exist and sized according to your needs) -> devio 9000 c:\temp\disk.img 0 0

On removable medias (such as USB disks), Windows can only access one partition at a time.
This is a driver limitation (which you can actually work around by using another driver but this is not the point of this article).

Here below one way to work around this.

First, lets select our device in CloneDisk and under the disk (right) menu : (1) put it offline, (2) delete disk layout, (3) create 2 (or more) partitions, (4) put your disk online.

Note that if you disk is already multi partitioned, you can skip the above 4 tasks and go the last part of this article which is about accessing the second partition.

Create one partition, and repeat this task once.

Once done (i.e partitions are created), it should looks like this once done (2 times 2 GB partitions).

In CloneDisk main window, put your disk online : windows should detect a new volume and offer to format it (if not, remove and reinsert media).

Create a folder named ‘part1’ (this is only a witness/indicator)

Now, lets see how we can access the second partition : Go back to CloneDisk -> Disk -> Partition Editor, select your second partition and « set as partition number 1 ».

Again, windows should detect a new volume (the previous volume ‘part 1’ has disappeared) and offer to format it (if not, remve and reinsert media) – unless you have skipped the first part of this article.

Create a folder named ‘part2’.

You can now switch back and forth between your partitions on your removable media by using CloneDisk -> Disk -> Partition Editor, select your partition and « set as partition number 1 ».
