- terminal 1
```
cd services
yarn run-blob-service-dev-mode
```
- terminal 2
```
cd services
yarn run-backup-service-dev-mode
```
- terminal 3
```
git clone https://github.com/karol-bisztyga/grpc-playground.git
cd grpc-playground
git checkout backup-async
```
You can hard-code some fake backup-id in the code (`Client.h` - `lastBackupID`)
```
./build.sh
./cmake/build/bin/client
```
Then in terminal 3 create a new log
```
l
```
With an invalid current backup id, the log cannot be sent.
