Backup GoCD Server

You can use GoCD’s administration interface to perform an One-Click Backup of GoCD. You can also perform a backup using the API.

Steps to initiate backup

After you are logged into GoCD, click on the Admin > Backup link, and click the Perform Backup button.

Note: GoCD will be unusable during the backup process.
Backup time is proportional to the database and configuration size. We suggest you backup GoCD when the GoCD Server is idle. Users who are logged into the GoCD Dashboard will be redirected to a maintenance page during the backup. On completion of the backup they will be redirected to the page they were on.

What is backed up?

The backup will be performed into the ${ARTIFACT_REPOSITORY_LOCATION}/serverBackups directory. ${ARTIFACT_REPOSITORY_LOCATION} for your server can be found as mentioned here.

The backup directory will be named backup_{TIMESTAMP} where the ${TIMESTAMP} is the time when the backup was initiated.

Database - This depends on the kind of database being used:
- If you’re using H2: This is in a zip called db.zip. The zip has a single DB file called cruise.mv.db.
- If you’re using PostgreSQL:
  - The database backup is a single file called db.DATABASE_NAME, where DATABASE_NAME is the name of the database. For instance, it could be called: db.gocd.
  - See PostgreSQL documentation regarding backup and restoration.
  - Note that the configured PostgreSQL database connection properties can affect the output and contents of the backup.
- If you’re using MySQL:
  - The database backup is a single file called db.DATABASE_NAME, where DATABASE_NAME is the name of the database. For instance, it could be called: db.gocd.
  - See MySQL documentation regarding backup and restore.
  - Note that the configured MySQL database connection properties can affect the output and contents of the backup.
Configuration - This is in a zip called config-dir.zip. This zip contains the XML configuration, Jetty server configuration, Keystores and all other GoCD’s internal configurations.
Wrapper Configuration - This is in a zip called wrapper-config-dir.zip. This zip contains configuration files for startup properties for the server.
XML Configuration Version Repo - This is in a zip called config-repo.zip. This zip contains the Git repository of the XML configuration file.
GoCD version - This is a file called version.txt. This file contains the version of the GoCD server when the backup was initiated

What is not backed up?

The following are not backed up as a part of the GoCD backup process. Please ensure that these are manually backed up regularly.

Artifacts - Please refer to this section to find out how to deal with artifacts
Log Files
Plugins - These are found at ${SERVER_INSTALLATION_DIR}/plugins/. This contains both the external and bundled plugins.
Addons - These are found at ${SERVER_INSTALLATION_DIR}/addons/. This contains installed addons.

Strategy to backup Artifacts and Test Reporting Data

Artifacts and the Test Reporting Data keep getting new files and directories added to them. So, it is a good idea to use rsync to copy the contents of these two into a backup location.

For Instance: Lets say you have a copy of all the files till 12-02-2012 in a location. On 20-02-2012, you can do something like:

rsync -avzP ${ARTIFACT_LOCATION} ${BACKUP_LOCATION}

This makes sure that only the files and directories that got newly added will be synced to the ${BACKUP_LOCATION} and not the entire contents.

Restoring GoCD using backup

The restoration process is not automated and needs to be done manually. Please refer to the previous sections about the contents of the backup.

Steps to restore

In order to restore the GoCD server from a backup, the server must first be stopped. Make sure the process is completely dead before starting the restoration.
Choose the backup directory that you want to restore from.

Note: Please ensure that you are not restoring a GoCD backup onto a GoCD version that is older than the one that was used to perform the backup.

For example: A backup using GoCD version 19.3 cannot be restored onto GoCD version 19.2. See the file version.txt in the backup directory to know the version of GoCD that was used to perform the backup
Database - This depends on the kind of database being used:
- If you’re using H2: Unzip db.zip and copy the file cruise.mv.db found inside it to the directory ${SERVER_INSTALLATION_DIR}/db/h2db.
- If you’re using PostgreSQL: Use psql to restore using the database backup file (for instance db.gocd). This depends on how you connect to the database. Example:
```
psql -d my_new_db -h my.db.host.com --password <db.gocd
```
  See PostgreSQL documentation regarding backup and restoration.
- If you’re using MySQL: Use mysql to restore using the database backup file (for instance db.gocd). This depends on how you connect to the database. Example:
```
mysql -D my_new_db -h my.db.host.com -u root -p <db.gocd
```
  See MySQL documentation regarding backup and restore.
Configuration - Unzip the config-dir.zip into a temp directory. Copy all the files from this directory to ${SERVER_INSTALLATION_DIR}/config directory on Windows and Mac or /etc/go on Linux.
Wrapper Configuration - Unzip the wrapper-config-dir.zip into a temp directory.

Note: If you are restoring a backup onto a different GoCD version, or you have modified the ${SERVER_INSTALLATION_DIR}/wrapper-config/wrapper.conf please diff the backed up files with the pre-installed versions for any differences. Newer GoCD versions can change the default properties required to start GoCD correctly and your old configuration file may not work correctly.

After reviewing (or merging changes into a third copy), copy all the files from your temp directory to ${SERVER_INSTALLATION_DIR}/wrapper-config directory.
Configuration History - Unzip the config-repo.zip into temp directory. Recursively copy all the contents from this directory to ${SERVER_INSTALLATION_DIR}/db/config.git .
Make sure the ownership of all the files that are restored are the same as the user running the Go server.

For example: Make sure you run a chown -R go:go ${SERVER_INSTALLATION_DIR}/db/h2db after Database restoration.
Start the GoCD server
