gitbucket-h2-backup-plugin Gitter Travis

This plugin enhances GitBucket by offering a way to backup/dump the entire H2 database of GitBucket.

It originates from pull request #845 and can be used to address database backup described in GitBucket Backup Documentation

Features

H2 Backup

This plugin allows to backup the underlying H2 database used by default by GitBucket.

Usage

The plugin provides 2 ways to backup the H2 database:

  • via an administration page and a backup button
  • via an HTTP call to http://YOUR_GITBUCKET/database/backup

The default backup file points to GITBUCKET_DATA/backup/gitbucket-db-YYYY-MM-DD-hhmm.zip where:

  • GITBUCKET_DATA is the standard GitBucket data directory. If not specified, default it's ~/.gitbucket
  • YYYY-MM-DD-hhmm represents a date with hour and minutes

UI usage

  • goto the System Administration menu, section H2 Backup
  • modify the file path if the default one doesn't fit your needs
  • hit the Export database button

HTTP call usage

Using your preferred tool (curl, wget, ...) it is possible start a backup of the H2 database.

The URL to call looks like http://YOUR_GITBUCKET/database/backup.

You can pass an optional argument dest that references the destination file path where the backup will be done on the server. For example calling http://YOUR_GITBUCKET/database/backup?dest=/var/backups/gitbucket.zip will do an H2 backup of the gitbucket database into the file /var/backups/gitbucket.zip. Since 1.3.0, the dest parameter can denote a relative file path, in this case the file will be created relatively to GITBUCKET_DATA.

On success, you will receive a HTTP 200 answer with a body containing done: FULL_PATH_OF_BACKUP_FILE.

Securing backup endpoint

In version 1.4.0, it is possible to secure the database/backup endpoint:

  • launch GitBucket with System property secure.backup set to true (for example -Dsecure.backup=true on the command line)
  • due to actual limitations of GitBucket & plugins security, once the previous setting is activated, a call to http://YOUR_GITBUCKET/database/backup will be temporary redirected http://YOUR_GITBUCKET/api/v3/plugins/database/backup. You have to follow this temporary redirection.
    • if you call the endpoint using httpie, use the --follow parameter
  • this secured endpoint route is TEMPORARY you should not call it directly. If you do think that it will change in the future when GitBucket will support secured routes for plugins.
