Incrementally clones Linux drives
Installation | Basic Usage | Documentation | Contributing
A lone hard drive stands atop a data heap, staring at the full moon. Suddenly, it transforms…into a bootable clone of your drive, whirring hungrily at the digital moon.
WereSync takes a Linux hard drive and effectively clones it, but works incrementally so you don’t have to spend so long backing up each time. Additionally, WereSync can clone to a smaller drive, if your data will fit on the smaller drive. Because WereSync uses rsync to copy, it can copy a running drive, though certain parts of state may not be preserved.
Why Use WereSync?
Hopefully, you think this project looks amazing and you want to try it right away. However, you may be skeptical about the usefulness of WereSync. You may be thinking, I can do this exact same thing using gparted or ddrescue. Hear me out! There are a few reasons to use WereSync over the other tools.
Unlike dd or CloneZilla, WereSync requires a low level of technical skill and an easy learning curve
WereSync can run while the your main drive is being used, instead of blocking your computer up for hours at a time
WereSync will incrementally update clones, making subsequent clones much faster.
WereSync works quickly, a single command copies your entire drive, no booting to live CDs or managing MBRs.
WereSync can copy to a smaller drive, provided your drive’s data will fit.
WereSync creates new UUIDs for the new partitions, allowing you to use the old and new drives alongside each other.
In the future, WereSync will also make the clone bootable, but at the moment the complexity of bootloaders means that WereSync clones will require manual bootloader installation before they work.
Full documentation may be found here.
WereSync can be installed using the setup.py file.
$ ./setup.py install
If you have pip installed, you can easily install WereSync with the following command:
$ pip install weresync
For more in-depth instructions, see the installation documentation.
Note: WereSync requires root capabilities to run because it has to access block devices.
The gui can be launched with the command:
$ sudo weresync-gui
Which generates the following GUI, though generally the advanced options are unneeded:
To see the options for the terminal command use:
$ weresync -h
To copy from /dev/sda to /dev/sdb (the two drives must have the same partition scheme) use:
$ sudo weresync /dev/sda /dev/sdb
For more information, including how to copy the partition table from drive to another, see the Basic Usage documentation page.
Documentation can be found on the Read the Docs.

WereSync currently has huge need of people testing the program on complex drive setups. In order to do this please:
Install WereSync from pip:
pip install weresync
Run it on your system:
sudo weresync -C source_drive target_drive
Report any errors to the issue tracker. Please be sure to post the contents of /var/log/weresync/weresync.log and fdisk -l.
All contributions will be greatly appreciated!
