Presets backup

[wachterjohannes]

Plugins should be able to hook into a backup process and extend configuration.

To achieve that the architecture has to be refactored. The whole process should be handled over events.

• PRE_BACKUP_EVENT:
  • Create destination and source
  • Create and fill system-database (with basic values)
  • (optional - with plugins) The configuration can be extended
• BACKUP_EVENT: Thrown foreach backup-part
  • Create part-database and write started to database
  • Find plugin
  • Resolve options
  • Call backup from plugin (inclusive exception handling)
  • Write finished, close and write database
• PRE_BACKUP_EVENT:
  • Write informations to database
  • Close and write system-database
  • Close destination & source

Same for restore.

The preset can hook into the PRE_BACKUP_EVENT. The check command should also be able to extend it. Maybe also call an CHECK_EVENT or a better name which can also be used.

Preset should have a PresetPool hook into the events and hold PresetInterface objects.

This Architecture should enable also other features in the future and make extensions more powerfull.

The complete event-architecture is not as good as it looks i will create a smaller step where the events will be thrown but a lot of the logic will be implemented in nanbando core class
