It is hard to distinguish backup from replication.
To figure out what the backup and replication are, you gotta get their definitions cleared.
Thats the most confusing point for most readers.
So lets start with that!
What Is Backup?
First of all, what is backup?
Therefore, we often discuss backup and recovery as a close tie.
They are so much important in our daily work.
What Is Replication?
Backup vs Replication
Next, this part will compare backup to replication based on their different features.
There are four major parts that will help you better distinguish the difference between backup and replication.
You will learn the characteristics of fault tolerance and high availability separately.
And then, this article will give you an overall comparison between them.
And what is failover used for?
Work Principle of Backup vs Replication
How do they work for data protection?
The backup is performed periodically and a save point for all data is created on the production server.
Data is backed up across a variety of media and locations, both in-house and in the cloud.
Transaction data and other data are replicated across multiple databases.
Replication types there are five replication types.
Snapshot Replication a copy of the snapshot database that appears the moment the replication process starts.
Transactional Replication a copy of the database with new data coming in as the database changes.
Merge Replication a copy of data from several sources into a single database.
Heterogeneous Replicationreplicated data between servers supplied by different vendors.
Peer-to-Peer Transactional Replication it allows all participating users and servers to send data to each other.
Compared to replication, backup is a relatively low-cost way to avoid data loss.
Besides, replication is often used for mission-critical applications that must always be up and running.
Can you use replication instead of backup?
The answer is NO.
the above contents have told you that they have different working purposes for data protection.
Data backup focuses on restoring data to a specific point in time while data replication focuses on business continuity.
Step 2: Switch to theBackuptab and click theSourcesection.
Choose your backup source and clickOKto save it.
Note: System has been selected as backup content by default.
if you want to back up your system, you dont need to change it.
Choose your destination path and clickOKto save it.
The delayed backup task is on theManagepage.
This article has clarified what backup and replication are separately and their differences.

However, transactional replication needs a primary key for the table.
In case you have tables without a primary key, you will not be able to use those tables.
Replicated data can also improve and optimize server performance.
When businesses run multiple replicas on multiple servers, users can access data faster.
Having multiple copies may lead to consistency problems.
