Plugin Backup for Jira

Download and backup user-installed Jira plugins as JAR files. View all installed plugins in a single admin page, download individually, or export everything as a ZIP archive.

Why

Jira administrators often need to backup installed plugins before upgrades, migrations, or disaster recovery. This plugin provides a simple way to download all user-installed plugin JARs — either one by one or as a single ZIP file.

Use cases:

• Backup plugins before a Jira version upgrade
• Export plugins when migrating to a new instance
• Keep an offline copy of your plugin set for disaster recovery
• Audit which plugins are installed and their file sizes

Compatibility
