Plugin Backup for Jira — Free Plugin to Download and Backup Your Jira Plugins

We’ve released Plugin Backup for Jira — a free plugin for Jira Data Center that lets administrators download installed plugins as JAR files.

The problem

Jira doesn’t provide a built-in way to download user-installed plugins. If you need to backup your plugins before an upgrade, migrate to a new instance, or simply keep an offline copy — you have to dig through the filesystem manually.

What Plugin Backup does

The plugin adds a page to the Jira admin panel where you can see all user-installed plugins with their names, sizes, and modification dates. From there you can:

  • Download any plugin as a JAR file with one click
  • Download all plugins as a single ZIP archive
  • List plugins via REST API for automation and scripting

Web interface

After installation, go to Administration → Plugin Backup in the left sidebar. You’ll see a table with all installed plugins and download buttons.

REST API

All endpoints require Jira administrator permissions. Authentication works via session cookie, Basic Auth, or Personal Access Token (PAT).

List installed plugins

GET /rest/plugin-backup/1.0/list

Returns a JSON array with plugin names, file sizes, and modification dates:

[
  {
    "name": "epic-cloner-1.0.0.jar",
    "size": 319488,
    "modified": "2026-04-05 20:20"
  },
  {
    "name": "markdown-extra-2.1.0.jar",
    "size": 1548200,
    "modified": "2026-03-15 14:30"
  }
]

Download a single plugin

GET /rest/plugin-backup/1.0/download?name=epic-cloner-1.0.0.jar

Download all plugins as ZIP

GET /rest/plugin-backup/1.0/download-all

Returns a ZIP archive named jira-plugins-YYYY-MM-DD.zip containing all user-installed plugin JARs.

Example with curl

# List plugins
curl -u admin:password https://your-jira.com/rest/plugin-backup/1.0/list

# Download one plugin
curl -u admin:password -OJ 
  https://your-jira.com/rest/plugin-backup/1.0/download?name=epic-cloner-1.0.0.jar

# Download all as ZIP
curl -H "Authorization: Bearer YOUR_PAT_TOKEN" -OJ 
  https://your-jira.com/rest/plugin-backup/1.0/download-all

Security

All endpoints and the admin page are restricted to members of the jira-administrators group. Non-admin users receive a 403 Forbidden response.

The plugin runs entirely within your Jira instance — no data is sent to external servers, no analytics, no telemetry.

Compatibility

  • Jira Data Center 9.x and above
  • Tested on Jira 9.12.30
  • Java 8+

Installation

Upload the JAR through Administration → Manage apps → Upload app, or install from the Atlassian Marketplace.

Source code

The plugin is open source: github.com/plainward/jira-plugin-backup
