How to Create Local Backups of SharePoint Libraries
Question details
The user wants to establish a method for automatically creating scheduled local backups of SharePoint Online document libraries.
- Product
- SharePoint Online
- Device & OS
- not provided
- Scenario
- Securing cloud data by maintaining local offline copies of important SharePoint document libraries on a computer or RAID array.
- Observed behavior
- SharePoint Online does not have a built-in feature for automatically scheduling and downloading local backups.
Ensure you have SharePoint administrator privileges and adequate local storage capacity on your target drive or RAID array to accommodate the entire document library.
Use a PowerShell Script for Automated Downloads
PowerShell allows administrators to script the downloading of SharePoint libraries and schedule the process using Windows Task Scheduler.
Using the PnP PowerShell module is one of the most effective ways to extract files from Microsoft 365 environments. This method requires some scripting knowledge but offers full control over what is downloaded and when.
Open PowerShell as an administrator and run the command 'Install-Module -Name PnP.PowerShell' to install the necessary SharePoint modules.
Use the 'Connect-PnPOnline -Url <YourSiteUrl> -Interactive' command to authenticate and connect to your SharePoint site.
Write a PowerShell script that loops through the target document library and uses the 'Get-PnPFile' cmdlet to download files to your designated local folder.
Open Windows Task Scheduler, create a new Basic Task, and set the action to start a program. Enter 'powershell.exe' with the path to your script as the argument to automate the backup.
Create a Power Automate Workflow
Power Automate can be configured to automatically copy new or modified files from SharePoint to a local server using a data gateway.
Use a Specialized Microsoft 365 Backup Service
For enterprise environments, dedicated third-party backup solutions provide robust, automated, and incremental local backups without custom scripting.
Manage Your Local Document Backups with WPS Office
Once you have successfully backed up your SharePoint libraries to a local drive, you need a reliable office suite to open and manage those files. WPS Office is a lightweight, free alternative to Microsoft Office that lets you view and edit your backed-up Word, Excel, and PowerPoint documents seamlessly offline.
- 1. Install WPS Office: Download and install WPS Office on the computer where your SharePoint backups are stored.
- 2. Access your backups: Navigate to your local storage or RAID array containing the downloaded SharePoint files.
- 3. Open and edit offline: Double-click your documents to open them directly in WPS Office for offline viewing and editing.
Frequently Asked Questions
Can I sync SharePoint libraries locally using OneDrive instead of backing them up?
Yes, you can use the OneDrive sync client to sync SharePoint libraries to your local PC. However, a sync is not a true backup; if a file is deleted or corrupted in SharePoint, it will also be deleted or corrupted in your synced local folder.
Does Microsoft 365 provide native retention for SharePoint?
Yes, Microsoft 365 offers retention policies and version history. These tools protect data from accidental deletion within the cloud environment but do not create offline local copies.
What permissions are required to download an entire SharePoint library via PowerShell?
You typically need Site Collection Administrator or SharePoint Administrator privileges to securely access and automate the download of all files within a document library.
Will a Power Automate flow handle large SharePoint libraries efficiently?
Power Automate is best suited for incremental updates (copying new or modified files). For massive bulk downloads of an entire library, a PowerShell script or a specialized backup service is more reliable and helps avoid API throttling limits.
