Backup for Microsoft Teams, Layer 2 GmbH, press release

Backup for Microsoft Teams – do it yourself quickly and easily

Many companies rely on Microsoft Teams for digital collaboration. Simple communication via chat and video, fast file exchange and joint work on documents ensure that more and more files important to the company’s success are stored in the cloud. When managing a Microsoft 365 environment, the question of a backup solution becomes increasingly important.

Cloud storage alone is not a backup

In the past, the lack of a comprehensive backup solution was often an argument against using cloud services. On the one hand, we now see it becoming more and more important for companies to back up files from Teams, OneDrive or Exchange. On the other hand, many companies do not know that, as users of Microsoft cloud services, they are responsible for adequate data backup and that cloud storage alone does not represent a backup in the true sense of the word.

Although Microsoft guarantees the availability of services according to the license, among other things it puts the possibility of restoring data in the hands of the user. For example, if a user accidentally deletes a file in a SharePoint library, it can be restored from the recycle bin, but after 93 days it is automatically deleted or the recycle bin is manually emptied, at which point the file is permanently deleted.

Keyword: business continuity – what are the options?

As part of business continuity, it is therefore absolutely necessary to design backup solutions for the cloud services in use. You can:

  • Use native options such as the recycle bin and version management.
  • Develop a separate backup solution for local on-premises systems and cloud data. Note: Using different solutions causes more administrative effort.
  • Upload local data to the cloud, such as Azure Storage or Backup, and integrate it into a cloud-based solution
  • Back up data and systems locally, sync cloud data to a file server and integrate it into your local backup solution.

Integrate cloud data from Microsoft Teams into your on-premises backup solution

We use the Layer2 Cloud Connector to back up data and systems locally, sync cloud data locally, and integrate it into your local backup solution. It’s the link between your local backup software and each channel’s files in Teams. A link file is created for each group, which copies all files from a channel to a network drive. From there, the files are accessed from your local backup solution.

Four steps to a local backup of Microsoft Teams – let’s go!

  1. Set up an initial connection (template connection) manually between a group and your file system with the Layer2 Cloud Connector.
  2. Run the PowerShell script to create the login files for each group for which you have permissions.
  3. Copy the generated connection files to the Layer2 Cloud Connector connection folder and click “Reload Configuration”.
  4. And your files from Microsoft Teams will be synced and the network drive path will be integrated into your local backup solution.

Detailed documentation, including screenshots and the PowerShell script, can be found in Layer2-Microsoft-Teams-Connection-Creator.zip in Layer2 Magazine, provided in English by our team of top Layer2 solutions.

In addition to integrating into a backup solution, you can also use the method described to create a simple backup to external storage to ensure redundancy of your data. Note that the Layer2 Cloud Connector does not create versions locally, but also performs configuration-based create, update, or delete operations. So it can happen that a file deleted in the cloud is also deleted in the “Backup” path.
