Nowadays hundreds of GB....


The Cloud

Nowadays


The Cloud

Not only storage


Azure Blob Storage


Backups to Azure

We can take advantage of Blob Storage to send

backups to the cloud!

Tapes? Why?

Worry about disk space? Never more!

Damaged storage? Azure is Geo-Redundant.

And more...

This is an offsite backup solution.

And you pay as you use!


Backups to Azure

In summary...

Mnimizes overall costs

One more option for backup DR.


Backups to Azure

Simple steps to follow:

1. Create a container under your Azure Storage account.

2. Download the Publishing Profile.https://manage.windowsazure.com/publishsettings/

3. Create the Credentials.

4. You are ready!

https://manage.windowsazure.com/publishsettings/


Managed Backups

Managed Backups – what’s that?

Still about backups? Yes!

The difference: it automates and manages SQL

Server backups, based on a retention period.


Managed Backups

FULL Backup Schedule

When MB is

enabled.

When log grows

more than 1 GB.

If the last FULL is 1

week older.

When log chain

breaks

Log Backup schedule

When a FULL

backup is performed

When there are no

log backups.

If t-log grows >5 MB

When last backup is

2h older.

Database Files in Azure

We can store DB files in Azure!

SQL Server 2012 SP1 – CU2+

Supports data and log files.

AzureOn-Premises



Good for small/non-critical databases

Performance is improving but can be a barrier.

Good option to create a low-cost DR solution!

Do not forget to save a

copy of db level objects in

Azure Storage.



Steps:

1. Create a Credential in the SQL Server instance.

2. Create a credential.

• The credential name = Container Path.

• This is not a simple process.

• I used a method with PowerShell, explained at this blog:

• http://sqlcommunity.com/SQL-TEAMS/SQLCAT

• Create/attach the dabase pointing to that container.

Cloud Witness

Introducing Cloud Witness

New kind of failover cluster witness

Windows vNext (2016?)

Leverages Microsoft Azure

It uses Microsoft Azure Blob Storage

Advantages:

No need for 3rd separate datacenter.

Same Storage Account can be used for multiple clusters.

One blob file per cluster.

Very low-cost (few read/write operations)

Cloud Witness

Steps to configure the Cloud Witness

Create Azure Storage Account.

A container named “msft-cloud-witness” will be created.


Cloud Witness

Access the Cluster Quorum configuration as

usual...


Cloud Witness

A new option is now available.


Cloud Witness

Fill the storage account name and account key...


Cloud Witness

And that’s all!


Hybrid Partitioning

Azure storage is useful for more!

Build a simple data archival model.

By partitioning a table and sending older data to Azure.

Other Solutions


Stretch Database

Stretch Databases - Data archival solution.

Based on Azure SQL Database

SQL Server 2016 feature.

Archives historical data – send to the cloud

Two modes:

Archive Table – Moves all the table.

Archive Row – Moves rowa based on rules.

Advantages:

Performance improvements.

Reduced database/backup size.

Backup run faster.


Stretch Database

Stretch Databases - Data archival solution.

No changes to existing queries and client apps.

Reduced cost and complexity.

Stretch Database

Requisites

Azure account.

Stretch database uses an underline Azure SQL Database.

Enable “Strech” on local instance.EXEC sp_configure 'remote data archive';GOEXEC sp_configure 'remote data archive' , '1';GORECONFIGURE;GO

After that you are good to run the wizard...


Strech Database

Types

sql_variant

XML

CLR user-defined types

(UDTs)

Features

Column Set

Computed Columns

Check constraints

Foreign key constraints that

reference the table

Default constraints

XML indexes

Full text indexes

Spatial indexes

Clustered columnstore indexes

Indexed views that reference the

table

SQLServer 2016 Upgrade Advisor


Availability Groups Replica

Availability Group supports replicas in Azure

Since SQL Server 2012 SP1 CU2+

Works as a DR/LB strategy.

Offload workload (reports, backups, ...).

Low-cost DR strategy.




A “wizard” that helps on this task – SQL Server 2014+




Or you can join manually...

1. Deploy the Azure VM

2. Join into the domain

3. Join into the cluster

4. Enbale HADR feature.

5. Joint to AG.

6. Start syncing the databases.


Are you ready to jump?
