Different Types Of Sql Server Backups
Full. This is the most common backup type and it includes everything including objects, system tables data, and transactions that occur during the backup. With a full backup, you can restore your database to the state, when it was backed up. Full backups wont truncate your transaction log but if your database is in full recovery you. should also consider transaction log backups
See also: A walk through the SQL Server 2016 full database backup
Differential. This type of backup offers a means to maintain a complete history of your database but without storing redundant data. A differential backup retains data since the last full backup. A differential backup is only useful if used in tandem with a full backup, but allows you to delete/remove previous differential backups as they are redundant
Transaction log. This backup type will backup all of the transactions that have occurred since the last log backup or truncation, then it will truncation the transaction log. This will capture all transaction information, both DML and DDL, that has occurred on the database. With a transaction log backup, you can restore a database to a particular point in time aka point-in-time recovery, like right before a data loss event

Things You Need To Know Before Backup Restoration
Before you proceed with the backup restoration process, you will need to:
- Close all the active connections before attempting to restore SQL Server database from .BAK file. Doing so will prevent the restore process from failing due to active database connections.
- Backups that are created on recent SQL Server versions cannot be restored to earlier versions of SQL Server.
- Backup the active transaction log, before performing the full database backup. This is because, if the active transaction log becomes unavailable, all transactions in that log will be lost.
- When you want to restore a db from another server instance, you will need to manage metadata to make the db available on another server. Refer to this link for more information.

Azure Backup: For Sql Hosted Databases Step By Step
Backing up an SQL server is usually done with SQL Server Management Studio . It’s a straightforward process that hasn’t changed much since SQL Server was released. Backup targets are usually disks or tapes, since such formats are still the preferred and most reliable offline methods for storing data.
A newer approach in Azure database backup is to back up your database directly to a cloud storage service. SQL Server enables you to back up your data to Azure Blob Storage, which is a fairly cheap storage service, frequently used for Azure cold storage. Azure Blob Storage stores your data redundantly in at least three locations inside the same Azure data center the maximum amount of redundant storage available stores data redundantly across all the 38 Azure regions and data centers currently located around the globe. This dispersal is one of the clear benefits to cloud hosted databases.
Backing up your data to a URL is a feature that was introduced in SQL Server 2012 SP1 CU2.
Additional enhancements were introduced to this feature in SQL Server 2016 that enables usage of block blobs for data storage, Shared Access Signatures for enhanced security, and striping for enhanced performance.
Lets go through the steps required to configure backup for SQL database to Azure.
The Azure storage used for storing the SQL database backup should be created and configured as a prerequisite.
Review the settings and proceed to create the storage account.
