Upload is not a part of the backup operation

[e-grigorov]

Currently, there are two standalone operations in a sequence i.e. a backup with BACKUP_STARTED and BACKUP_FINISHED, right after the upload starts. There are pros and cons of this approach:

• Pros:
  • Many backups can be done on the edge device in offline mode and when online they can be uploaded.
  • Clear visibility of the operations i.e. if there is a fail in the backup it's clear that this fail is in the backup preparation.
• Cons:
  • BACKUP_FINISHED is reported but the backup is not uploaded on the backend.

The disadvantage seems serious and cover the typical/normal flow of the feature. That's why this ticket aims to revise and clear the issue.
