Datto Block Driver is a kernel module for taking block-level snapshots and incremental backups of Linux block devices. It provides functionality similar to VSS on Windows, but on any block device.

References

Install

On Ubuntu, see INSTALL.md:

sudo apt-key adv --recv-keys --keyserver keyserver.ubuntu.com 29FF164C
echo "deb https://cpkg.datto.com/repositories $(lsb_release -sc) main" | sudo tee /etc/apt/sources.list.d/datto-linux-agent.list
sudo apt-get update
sudo apt-get install dattobd-dkms dattobd-utils

Usage

dbdctl is the userspace tool used to manage the dattobd kernel module. It comes with a man page (see issue #91 if not installed):

man dbdctl                      # Get the manpage
