 ## Backup and Restore data using MGOB
+You can implement backup and restore feature on the Sugarizer School Portal MongoDB replicaset by using MGOB.
 [MGOB](https://github.com/stefanprodan/mgob/) is a MongoDB backup automation tool built with Go. It features like scheduled backups, local backups retention, upload to S3 Object Storage (Minio, AWS, Google Cloud, Azure) and upload to gcloud storage.
 
-To setup MGOB to automate MongoDB backups on Google Kubernetes Engine, follow these step by step instructions:
-
-Requirements:
-- GKE cluster minimum version v1.8
-- kubctl admin config
-
-### Store Service Account key as a secret
-First, you need to create a GCP service account key from the API & Services page. In case you already have one, then download the JSON file and rename it to `key.json`.
-
-Store the JSON file as a secret:
-```bash
-kubectl create secret generic service-acc-secret --from-file=key.json
-```
-
-### MGOB Installation
-Clone the MGOB repository:
-```bash
-git clone https://github.com/stefanprodan/mgob.git
-cd mgob/chart
-```
-Edit the chart's `values.yaml` file.
-- Set the appropriate `storageClass` for your provider.
-- Update the `mgob-config` `configMap`. Add `sugarizer-database` backup plan.
-Here is an example backup plan:
-```bash
-sugarizer-database.yml: |
-  target:
-    host: "mymongodb-mongodb-replicaset-0.mymongodb-mongodb-replicaset.default,mymongodb-mongodb-replicaset-1.mymongodb-mongodb-replicaset.default,mymongodb-mongodb-replicaset-2.mymongodb-mongodb-replicaset.default"
-    port: 27017
-    database: ""
-  scheduler:
-    cron: "0 0,6,12,18 */1 * *"
-    retention: 14
-    timeout: 60
-```
-- Add a reference to the secret. You can either insert your secret values as part of helm values or refer externally created secrets. In our case, we created a secret with a name `service-acc-secret`.
-```bash
-secret:
-  - name: service-acc-secret
-```
-An example YAML configuration is available as [mgob-gke.yaml](examples/mgob-gke.yaml).
-
-### Backup to GCP Storage Bucket (Optional)
-For long term backup storage, you could use a GCP Bucket since is a cheaper option than keeping all backups on disk.    
-You need to enable `storage.objects` acccess to the service account in order to allow objects creation in the bucket.    
-From the GCP web UI, navigate to Storage and create a regional bucket named `ssp-backup` (Or any other name if it's taken). Set the bucket and secret name in the backup-plan in the `values.yaml` file.
-```bash
-gcloud:
-  bucket: "ssp-backup"
-  keyFilePath: /secret/service-acc-secret/key.json
-```
-
-### Restoring data from backup
-In order to restore data to the Sugarizer School Portal database, you need to open a shell in MGOB pod. The backups are available in `/storage/sugarizer-database/` directory inside the pod (where `sugarizer-database` was the name of our backup plan).
-
-- In case of a database error in which you need to completely restore all the databases, you can run:
-```bash
-mongorestore --gzip --archive=/storage/sugarizer-database/sugarizer-database-xxxxxxxxxx.gz --host mymongodb-mongodb-replicaset-0.mymongodb-mongodb-replicaset.default:27017 --drop
-```
-- In case a school's DB is messed up and you need to restore that, you can run:
-```bash
-mongorestore --gzip --archive=/storage/sugarizer-database/sugarizer-database-xxxxxxxxxx.gz --nsInclude="db_name.*" --host mymongodb-mongodb-replicaset-0.mymongodb-mongodb-replicaset.default:27017 --drop
-```
-Where db_name is the name of the database to restore.
+To setup MGOB to automate MongoDB backups on Google Kubernetes Engine, you can follow this [documentation](https://github.com/nikhilm98/sugarizer-school-portal#backup-and-restore-data-using-mgob).
