Database Backup

Why Backups Matter

You need backups often to keep your data safe. Many IT leaders lost important data because they did not back up enough. Here are some facts:

• 76% of IT leaders lost important data last year.

• 45% could not get their data back.

If you do not back up, you can lose more than files. You might lose money, time, and trust. Here are problems that happen without backups:

• Losing data can stop your business.

• Losing product databases can stop online sales.

• Missing invoices can mess up your money.

• Fixing problems costs a lot and takes time.

• You might get fined for breaking data rules.

• Clients and suppliers may not trust you.

Backups help you fix problems, follow rules, and keep data safe. The table below shows why backups are needed:

Backup Steps

As a PowerShell DBA, you can use dbatools to make backups easy and less risky. Follow these steps for a full backup:

1. Open PowerShell.

2. Use the Backup-DBADatabase command.

3. Set your server with -ServerInstance.

4. Add your database name with -Database.

5. Pick the backup type with -Type (Full is default).

6. Choose where to save with -BackupDirectory.

7. Check your backup with Get-DbaLastBackup.

Here is a sample script:

Backup-DbaDatabase -ServerInstance "SQLSERVER01" -Database "SalesDB" -Type Full -BackupDirectory "C:\SQLBackups"
Get-DbaLastBackup -SqlInstance "SQLSERVER01" -Database "SalesDB"

You can set this script to run every day. This saves time and keeps backups current.

Restore Steps

Restoring a database is simple with dbatools. Automation helps you avoid mistakes like wrong file paths. Here is how you restore a database:

1. Install dbatools with Install-Module Dbatools and import it.

2. Use Restore-DbaDatabase with the right settings.

3. For a basic restore, run a script with your backup file.

4. For regular restores, set up a schedule.

5. For special restores, change the script as needed.

Example restore command:

Restore-DbaDatabase -SqlInstance "SQLSERVER01" -Path "C:\SQLBackups\SalesDB.bak"

Always test your backups. Use Test-DbaLastBackup to make sure your backup works. Run tests in a safe place, not on your main system.

Tip: Using dbatools to automate backups and restores helps you make fewer mistakes and saves you lots of time. The workshop will show these steps live so you can watch and try them.

SQL Server Migration

Migration Importance

Moving SQL Server data must be safe and fast. This job is very important for every PowerShell DBA. You need to plan well before you start. Always check your setup first. If you follow good steps, your data stays safe. Your business will not have big problems. Here are some reasons why migration is important:

• SQL Server migration has many steps and is not easy.

• You need to check your setup to stop surprises.

• Good planning keeps your data right and your business working.

Using dbatools to automate migration helps a lot:

• You can finish moving data in days, not months.

• You save money because you do not need outside help.

• You get reports that show your data matches the old system.

• Your team and leaders will trust you more.

Migration Steps

dbatools makes moving data easier. Here are the steps:

1. Install dbatools and load the module.

2. Set up login details for both servers.

3. Run the command to move databases, logins, jobs, and settings.

4. Test the new database to make sure it works.

Here is a PowerShell script you can use:

Import-Module dbatools
Start-DbaMigration -Source SQLInstance1 -Destination SQLInstance2 -Credential $SourceCredential -DestinationCredential $DestinationCredential
Invoke-DbaQuery -SqlInstance SQLInstance2 -Database SalesDB -QueryTimeout 10 -Query "SELECT TOP 10 * FROM Orders"

You can move many things, like databases, logins, jobs, mail objects, and more. The table below shows what you can move:

Tip: Use the -UseLastBackup option to make downtime much shorter.

Common Challenges

You might have problems when you move data. Here are some common problems:

• The last part of migration can bring new issues.

• Costs can go up if you do not watch closely.

• You must follow new rules to keep data safe.

• You need to make sure performance is good for your needs.

dbatools helps you fix these problems. You can move data to many servers. You can use backups to save time. You can use log shipping for big databases. The workshop will show real migrations so you can learn by doing.

Security Management

Security Basics

You need to keep your SQL Server safe from threats. Good security starts with knowing the main ideas. You work with three important parts:

You must watch for common security problems. Attackers look for weak spots. Here are the biggest risks you face:

1. SQL Injection lets attackers steal or change data.

2. Weak Authentication makes it easy for hackers to get in.

3. Unpatched Vulnerabilities leave your server open to attacks.

4. Exposed Network Interfaces can be targeted.

5. Excessive Privileges give users too much power.

6. Malware and Ransomware can lock or destroy data.

7. Data Exfiltration Techniques help attackers steal data quietly.

8. Misconfigured Server Settings make attacks easier.

9. Insider Threats come from people inside your company.

10. Insecure Third-Party Integrations can open backdoors.

As a PowerShell DBA, you should check your server often and fix problems quickly.

Permission Auditing

You need to know who can do things in your database. Auditing permissions helps you find weak spots and stop attacks. dbatools gives you easy commands to check permissions.

• Use Get-DbaUserPermission to see all permissions for users and logins.

• This command checks server logins, server-level permissions, database users, roles, and object-level permissions.

• You can change the command to include or skip public and guest permissions.

• You can also skip system objects if you want.

Here is a sample command:

Get-DbaUserPermission -SqlInstance "SQLSERVER01" -Database "SalesDB"

Tip: Run this command often to keep your database safe. Save the results so you can compare changes over time.

Automation for Security

You can use dbatools to fix security problems fast. Automation helps you update permissions and remove risky accounts. You save time and make fewer mistakes.

• Use Set-DbaDbUser to change user roles.

• Use Remove-DbaLogin to delete old or unused logins.

• Schedule scripts to run checks every week.

Here is a script to remove a login:

Remove-DbaLogin -SqlInstance "SQLSERVER01" -Login "OldUser"

You should follow best practices for secure SQL Server management:

• Give users only the access they need.

• Update your server and patch it often.

• Audit permissions and review logs.

• Remove unused accounts and roles.

• Use strong passwords for all logins.

Note: Automation with dbatools helps you keep your SQL Server safe. You spend less time on manual checks and more time on important work.

PowerShell DBA Automation Tips

dbatools Optimization

You can get more from dbatools by following a few smart steps. Start by keeping your dbatools module up to date. New releases often fix bugs and add helpful features. Use the Update-Module dbatools command to stay current.

Try to use scripts that work for many servers at once. You can use PowerShell loops to run the same command on several SQL Server instances. This saves you time and keeps your work consistent. Here is a simple example:

$servers = @("SQLSERVER01", "SQLSERVER02", "SQLSERVER03")
foreach ($server in $servers) {
    Get-DbaDatabase -SqlInstance $server
}

You should also use logging in your scripts. Logging helps you track what happened during each run. You can use the Start-Transcript and Stop-Transcript commands to save logs. This makes it easy to review your work and spot any problems.

Tip: In the workshop, you will see how to build scripts that handle many servers and log every step. This hands-on practice helps you become a more efficient PowerShell DBA.

Troubleshooting

Sometimes, you may run into issues with dbatools automation. You can solve most problems by following these steps:

1. Make sure you have the latest version of dbatools.

2. Check if you have the right permissions for the task.

3. Try running your script in a new PowerShell session.

4. Write down your dbatools version and SQL Server edition.

5. List the steps that cause the problem.

6. Use commands like Start-Transcript to collect logs and errors.

If you keep these steps in mind, you will fix issues faster and learn more each time. You can also join the dbatools community to share your questions and get help from others.

Note: The workshop covers real troubleshooting cases. You will learn how to spot errors, collect logs, and find solutions using dbatools best practices.
