Hello Harish,
If I understand correctly. You had 2 modules, but deleted one, however you expect the data to move over to the other module?
Unfortunately that's not how that works. If the modules are based on eachother you could've chosen to replace an existing module instead of creating a new module (and afterwards deleting the old one, which contained the data).
In order to restore your data, you have to deploy a version with Module 1 and 2 (an old revision) to your environment. Afterwards you can restore the backup to the environment and it should be back. If you head over to the backup section of your cloud portal, it will also state the exact revision and branch.
