Periodic Backup

Description

This plugin was created as alternative to existing Backup Plugin that would work periodically.
The main idea was to create a backup plugin that provides an easy way to be extended with new functionality in the future without the need of hacking around the code.
The plugin defines three extension points (basically plugins inside the plugin):

• FileManager - defines what files should be included in the backup and what will be the restore policy of the files. Example: ConfigOnly - will choose only the configuration XML files from HUDSON_HOME, all the configuration files of each job and the XML of every user if you are using an internal database for access control.
• Storage - specifies method of archiving and unarchiving backups. Example: ZipStorage - will compress backup files into a zip archive.
• Location - specifies localization of the backups. Example: LocalDirectory - will store the backup files inside the specified path.

Usage

1. After installing the plugin and restarting Jenkins, new icon will appear in the Manage Jenkins section.
   

2. After pressing Periodic Backup Manager in the side panel choose configure to set up the plugin.
   

3. In the configuration page set all the required parameters which are:

   • Temporary Directory - path to the directory for creating archives during backup, storing archives during restore, and unpacking their content. It is vital for PeriodicBackup that this directory is writable, empty, and outside of the Jenkins home directory.

   • Backup schedule (cron) - schedule following the syntax of cron (with minor differences). Validate cron button may be useful to check if the syntax of the input is correct. More about cron can be found here: http://adminschoice.com/crontab-quick-reference

   • Maximum backups in location - A number of existing old backups exceeding this value in each location will be deleted after backup.

   • Store no older than (days) - Backups older then number of days specified here will be deleted after backup.

   • File Management Strategy - choose a suitable FileManager and fill in required fields (if any)

   • Storage Strategy - add a suitable Storage(s) and fill in required fields (if any)

   • Backup Location - add a suitable Location(s) and fill in required fields (if any)

     Temporary Directory

     Please be aware the using a path inside Temporary Directory (for example for location like LocalDirectory) will lead to a very bad things (like loss of data).

4. After setting up all values correctly and pressing Save button, configuration will be persisted and user will be redirected to the main page of the plugin. Any backup available for restore will be listed here, and one can navigate here via Restore link from the sidepanel. The backup will be performed according to the cron schedule or when Backup Now! is pressed from the sidepanel. A message will be shown on the top of the page as on the picture below.
   

5. When the backup is successfully created it will be listed on the web page as on the picture below.
   
   To restore the backup it has to be chosen from the list and the "restore selected backup" button has to be pressed.

   Backup not showed/"Creating backup..."/"Restoring backup..." message does not disappear

   Sometimes the backup will not be shown on the web page just after performing the backup. Also the "Creating backup..."/"Restoring backup..." messages may not disappear from the page when they should. In that case page has to be refreshed or the link to Restore has to be pressed in order to show the new backup. This will be fixed in future by a widget informing about the current status of the backup/restore process
