Serveurs de fichiers - Episode 12 - Les clichés instantanés sous Windows Server 2022

Introduction

This tutorial covers the process of using snapshots in Windows Server 2022, specifically focusing on how to configure and utilize previous versions of files and folders. Snapshots serve as a valuable supplement to regular backups, allowing users to restore data to an earlier state without needing extensive recovery processes.

Step 1: Understanding Snapshots

• Definition: Snapshots, also known as previous versions, are point-in-time copies of files or folders.
• Purpose: They provide an easy way to revert back to earlier versions, especially useful in cases of accidental deletion or unwanted changes.

Step 2: Configuring Snapshots in Windows Server 2022

1. Access Server Manager:

   • Open the Server Manager on your Windows Server 2022.

2. Select the Volume:

   • Navigate to the "File and Storage Services" section.
   • Choose "Volumes" and select the volume for which you want to enable snapshots.

3. Enable Snapshots:

   • Right-click on the selected volume.
   • Click on "Configure Shadow Copies".
   • In the Shadow Copies window, select the desired volume and click on "Enable".

4. Adjust Settings:

   • Set the maximum size for the snapshot storage.
   • Configure the schedule for snapshots according to your requirements (e.g., daily, weekly).

5. Apply the Configuration:

   • Click "OK" to save the changes.

Step 3: Using Previous Versions

1. Accessing Previous Versions:

   • Right-click on the file or folder you need to restore.
   • Select "Properties" from the context menu.

2. Navigating to Previous Versions:

   • Go to the "Previous Versions" tab.
   • Here, you will see a list of available snapshots with their timestamps.

3. Restoring Files or Folders:

   • Select the desired version from the list.
   • Click "Restore" to revert to that snapshot.
   • Alternatively, you can click "Copy" to save the previous version to a different location.

Practical Tips

• Regularly check and manage your snapshot storage to prevent running out of disk space.
• Establish a clear schedule for snapshots based on how frequently files change in your environment.
• Educate users on how to access previous versions to empower them in managing their own data.

Common Pitfalls to Avoid

• Forgetting to enable snapshots on critical volumes, which can lead to data loss.
• Not setting an appropriate schedule, resulting in either too few snapshots or excessive storage usage.
• Overlooking the need for regular maintenance and review of snapshot settings.

Conclusion

By understanding and implementing snapshots in Windows Server 2022, you can significantly enhance your data protection strategy. Regular snapshots provide a safety net for file recovery and ensure that you can quickly restore data to previous states.
