Automatically Create Build Backups in Visual Studio
Automated Source Code Backups for Solo Developers
For developers working independently, a complex version control system might be overkill. However, maintaining backups of source code for each released version remains critically important.
Implementing Automatic Backups with Visual Studio
A streamlined solution can be achieved by utilizing post-build events within Visual Studio. This, combined with a basic batch script, allows for automated source code backups with every release build.
The process leverages the build process itself to trigger the backup. This ensures that backups are consistently created alongside each release.
A simple batch script can be configured to copy the entire project directory to a designated backup location. This location should be separate from the primary development directory.
By integrating this script into the post-build event settings, Visual Studio will automatically execute it after each successful release build. This creates a readily available archive of the code at that specific version.
This method provides a lightweight and effective way to safeguard your work without the overhead of a full-fledged version control system. It’s a practical approach for solo developers prioritizing simplicity and reliability.
The Underlying Process
The methodology employed is straightforward. Upon the completion of a successful build process, a batch script is automatically triggered.
This script generates a compressed archive – potentially including version tags and timestamps – encompassing all files contained within the designated Visual Studio project directory.
Essentially, this is the entirety of the system. The subsequent section details the necessary steps for implementation.
Implementation Steps
Following the outlined procedure will enable the functionality. Detailed instructions are provided below for ease of use.
Configuration
Ensure your build event is configured to execute the batch script after each successful compilation. This is a crucial initial step.
Archive Creation
The batch script will automatically compress the project files into a single archive. This archive serves as a readily available backup.
Versioning and Timestamps
Optional features include the addition of version tags and timestamps to the archive filename. These enhance organization and traceability.
Storage
Consider a robust storage solution for the generated archives. Regular backups are essential for data preservation.
Visual Studio project backups are now automated with this simple process.
Automating Build Backups in Visual Studio
To begin, download and extract the provided batch script file, accessible via the link at the article's conclusion. The 7-Zip command line tool is also required; it’s either included with the complete 'Project Build Backup' script package or can be obtained as a separate download.
For demonstration purposes, the necessary files were extracted to the "C:\Tools" directory, though any preferred location is acceptable.
Accessing Project Properties
Within Visual Studio, locate and double-click "My Project" under your project to open the project properties.
Navigating to Compile Settings
In the project properties window, select the "Compile" section.
Opening Build Events
In the lower-right corner of the window, click the "Build Events" button.
Configuring the Post-Build Event
We aim to create a backup following a successful compilation. Ensure the "On successful build" option is checked, then click the "Edit Post-build" button.
The Backup Command
The following command initiates a build backup specifically for the Release configuration. This conditional check, utilizing "IF "$(ConfigurationName)" == "Release"", prevents backups from being created during Debug or testing builds. The command also appends the current timestamp using the /D switch and utilizes the 7z archive format via the /7z switch, rather than zip.
IF "$(ConfigurationName)" == "Release" CALL C:\Tools\ProjectBuildBackup.bat "$(SolutionDir)" "$(ProjectDir)" "$(ProjectName)" /T "$(ConfigurationName)" /D /7z
The /T "$(ConfigurationName)" parameter appends the build type (Release in this instance) to the backup filename.
Utilizing Macros
The "Macros" button allows Visual Studio to automatically populate project-specific information, eliminating the need for manual coding. Adjust the command as necessary, particularly the path to the batch file, though the initial three parameters generally won’t require modification.
It’s crucial to remember that post-event operations execute irrespective of the selected project configuration. Therefore, the "IF "$(ConfigurationName)" == "Release"" statement is essential to prevent backup actions during every successful build.
Verifying the Command
After entering and applying the command, it should appear within the "Post-build events" section.
Importance of the CALL Command
Although not strictly required, the "CALL" command is strongly recommended. Its omission may prevent subsequent events from executing correctly.
Observing Backup Operation
When you initiate a build in the Release configuration, you will observe the output from the build backup process.

Backup Location and Structure
Each successful Release build generates a new, timestamped archive within a subdirectory named "Builds" (customizable using the /O switch) in the solution folder.
Backup Contents
The backup archive contains the complete Visual Studio project, including source files, configuration settings, compiled binaries, and all other project assets, providing a comprehensive point-in-time backup.
Not Intended as a Substitute for Comprehensive Version Control
To emphasize, this utility should not be considered a replacement for a complete version control system. Its purpose is to serve as a helpful resource for developers, enabling the creation of project source code snapshots following each compilation process.
Should the need arise to review a previous iteration, possessing a readily deployable project file—requiring only extraction to a new directory—corresponding to a specific compilation point can prove exceptionally beneficial.
This functionality streamlines the process of revisiting past states of the project, offering a convenient method for analysis and debugging.
Benefits of Project Snapshots
- Facilitates easy comparison of code between compilations.
- Provides a quick recovery point in case of errors.
- Supports investigation of past project behavior.
While not a substitute for robust version control, these snapshots offer a valuable supplementary approach to managing project history.
Developers can leverage this tool to maintain a readily accessible archive of their work, enhancing their ability to understand and resolve issues efficiently.

A script for creating project build backups can be downloaded here.
The 7-Zip command line tool is also required and can be obtained separately.
It's worth noting that the 7za utility is included when downloading the Project Build Backup script itself.
Additional Information
- The Project Build Backup script facilitates the creation of backups.
- 7-Zip provides the compression functionality used by the script.
- Using the script avoids the need for a separate 7-Zip installation in some cases.
Ensure both components are accessible for proper functionality.
The command line version of 7-Zip is essential for automated backup processes.
