This follows the 3–2–1 Backup Strategy of having 3 copies of data (On client, Primary Server and Replica Server) with 2 being local to you and 1 being offsite.Īn important note about making backups with rsync is that it is generally recommended to backup / as it will allow you to restore a complete data loss by copying all files onto a new device and rebooting. My primary server is located in my house and my replica is offsite. I have 2 backup servers, one is used as my primary (where I will always backup to) and the other as my replica (which will simply copy from the primary on a scheduled interval). I have multiple clients, many of them are not always on (ex: Laptop). I will also assume all of your servers and clients run Linux, this should be trivial to use on a Mac but will require a bit more effort for Windows. Setupįrom this point forward I will refer to a client as a computer being backed up and a server as a computer that is being used to store the backups. #Grsync export as rsync script installKeep in mind this script could be cloned to any language if you prefer not to install Node.js on your computers. I will be using Rsync-Snapshot a Node.js script I have written to manage script hooks (before and after backup), logging, deleting old increments and restores. This article will go through my setup with multiple computers backing up to two backup servers. Implementing this with rsync is fairly trivial, especially with the -link-from parameter however the system configuration is not. If data is changed we transfer the changes (file deltas) then recreate the file from the downloaded changes and unchanged parts on the disk. Essentially this takes advantage of hard links (linking to the inode of a file instead of duplicating its data) if data is unchanged between backups. #Grsync export as rsync script how toThese guides detail the methodology behind how to create increments with rsync. Two useful ones are: Snapshot Backup - Arch Linux Wiki and Do It Yourself Backup System Using Rsync. Guides already exist online detailing this idea. With configuration and scripting it can also be great for creating backups and even incremental snapshots (using methods similar to Apple’s Time Machine). These locations can be on the same physical computer (on the same disk or different disks) or can be on different computers (using SSH connections). But I just want to give you a bit of help to get started.Īt some point, you will be asked to enable WSL by opening a powershell.Rsync is a tool which allows users to “mirror” files between two locations. It's really easy and the documentation is great! And there is no need for plagiarism, so I won't repeat the installation instructions here. It lets developers run GNU/Linux environment - including most command-line tools, utilities, and applications - directly on Windows, unmodified, without the overhead of a virtual machine. The Windows Subsystem for Linux has been introduced in Windows 10. #Grsync export as rsync script windows 10To do this, you must have Windows 10 installed on your PC. #Grsync export as rsync script PcUse rsync to back up a folder on your windows PC to another folder on a different disk on the same PC And in this distribution, to run rsync.Įnable WSL and install a Linux distribution of your choice #Grsync export as rsync script fullStill, I wanted to be able to back up my precious collection of Georges Brassens, Serge Gainsbourg, and Renaud.Īnother solution is to install a full Linux virtual machine on the windows host, but that's really using a sledgehammer to crack a nut, and a complete waste of time and resources, especially disk space.īut now is the future! it's finally possible to run a Linux distribution on Windows 10 using Windows Subsystem for Linux (WSL). But I got some issues, for example when dealing with filenames with weird characters like the French accents. There were a few solutions, like running rsync with cygwin. The only drawback with this perfect backup tool is that it's not available on windows. : I never had any issue with it, and you can test what rsync will do with the dry run option before doing it. : for example, you can make backups to a remote machine, logging in as a different user. To use: one command is enough to synchronize a whole directory : it uses the size and modification times of the files to decide which files need to be transferred. If you're here, it's because you're desperately looking for a solution to run rsync on windows, so you probably know already that rsync is: , a tool that can synchronize the contents of two directories. And every time, I told myself that this would not happen ever again.Īt some point, I found the solution for macs and Linux computers: I can't count how many times I've lost files because I was too lazy to set up a proper backup. ![]()
