Backup and restore in GCP - Step-by-Step Execution

Process Flow - Backup and restore

Start Backup Process

↓

Identify Data to Backup

↓

Create Backup Snapshot

↓

Store Backup Securely

↓

Backup Complete

↓

↓

Restore Complete

The flow shows starting a backup by selecting data, creating and storing a snapshot, then restoring by selecting that snapshot and verifying success.

Execution Sample

GCP

gcloud sql backups create --instance=my-instance
# Backup created

gcloud sql instances restore-backup 20230401 --instance=my-restored-instance
# Restore started

This code creates a backup of a Cloud SQL instance and then restores it from a specific backup ID to a new instance.

Process Table

Step	Action	Input/Parameter	Result/Output	Next Step
1	Start Backup	Instance: my-instance	Backup process initiated	Identify Data to Backup
2	Identify Data	Database data and config	Data ready for backup	Create Backup Snapshot
3	Create Snapshot	Data from instance	Backup snapshot created with ID 20230401	Store Backup Securely
4	Store Backup	Snapshot 20230401	Backup stored in GCP storage	Backup Complete
5	Backup Complete	-	Backup process finished successfully	Start Restore Process
6	Start Restore	Backup ID 20230401	Restore process initiated	Select Backup Snapshot
7	Select Snapshot	Backup ID 20230401	Backup snapshot selected	Restore Data from Backup
8	Restore Data	Backup snapshot data	Data restored to instance	Verify Restore Success
9	Verify Restore	Restored data	Restore verified successful	Restore Complete
10	Restore Complete	-	Restore process finished successfully	END

💡 Restore process ends after successful verification of restored data.

Status Tracker

Variable	Start	After Step 3	After Step 6	After Step 9	Final
Backup Snapshot ID	None	20230401	20230401	20230401	20230401
Backup Status	Not started	Created	Created	Restoring	Completed
Restore Status	Not started	Not started	Started	Verified	Completed

Key Moments - 3 Insights

Why do we need to verify the restore after restoring data?

Verification ensures the restored data matches the backup and the system works correctly, as shown in step 9 of the execution_table.

Can we restore from a backup before it is fully created?

No, the backup must be fully created and stored first (step 4) before starting the restore process (step 6).

What happens if the backup snapshot ID is incorrect during restore?

The restore will fail because the system cannot find the backup to restore, so selecting the correct snapshot (step 7) is crucial.

Visual Quiz - 3 Questions

Look at the execution_table, what is the Backup Status after step 3?

A Created

B Not started

C Restoring

D Completed

💡 Hint

Check the 'Backup Status' variable in variable_tracker after step 3.

At which step does the restore process start according to the execution_table?

A Step 4

B Step 6

C Step 5

D Step 7

💡 Hint

Look for 'Restore process initiated' in the Result/Output column.

If the backup snapshot ID was missing, which step would fail?

A Step 8

B Step 3

C Step 6

D Step 10

💡 Hint

Refer to step 6 where the restore process starts using the backup ID.

Concept Snapshot

Backup and restore in GCP involves creating a snapshot of your data and storing it securely.
Use 'gcloud sql backups create' to backup and 'gcloud sql instances restore-backup' to restore.
Always verify the restore to ensure data integrity.
Backups must complete before restore starts.
Keep track of backup IDs to select correct snapshots.

Full Transcript

This visual execution shows the backup and restore process in Google Cloud Platform. It starts by initiating a backup on a Cloud SQL instance, identifying the data to backup, creating a snapshot, and storing it securely. After the backup completes, the restore process begins by selecting the backup snapshot, restoring data to the instance, and verifying the restore success. Variables like backup snapshot ID and status change step-by-step. Key moments clarify why verification is needed, the order of operations, and the importance of correct snapshot IDs. The quiz tests understanding of these steps and states.
