# Save a Version

## Guide

To save a [version](/features/version-control.md#versions) of a branched development file:

1. Go to Branches -> Versions
2. Select the desired file from the list
3. Select the top Active File line in the version list.
4. In the right sidebar, enter a version description and select Full Backup or Clone
5. When prompted, enter a [version number](#version-numbers).

{% hint style="warning" %}
Versions are backups of the development file. They can be either clones or full backups and the default choice can be specified in [Project Settings](/guides/projects/project-settings.md). For large file sizes (> 100MB), we recommend using Clone as default. Choosing Full Backup might result in bad performance on your development server.

## Version Numbers

Devin supports a wide variety of versioning conventions, but we recommend using a standard convention like [Semantic Versioning](https://semver.org) or similar that uses a format that looks like `MAJOR.MINOR` or  `MAJOR.MINOR.PATCH`.&#x20;

For more advanced use cases, like when you're dealing with pre-release versions, Devin also supports version numbers that include letters, such as `2.10.3-alpha` and `2.10.3-beta8`.
