Product characteristics

Backup principles

• A backup always looks like a full backup
  -> Always a fully consistent state is available
• A backup as default only stores the changed state of the predecessor
• A full backup can be forced

Device characteristics

• For each device there is a specific backup and restore procedure
  e.g. a backup and restore procedure for Android application packages
• For a device there can be more than one backup and restore procedures
  e.g. for the Android system and the Android application packages

Metadata characteristics

• Metadata is always stored with a backup together
• Part of the metadata is depended on the device or the backup and restore procedure
• Metadata is stored in a platform independent way
• Metadata must be both machine and human readable
