OneDrive for Business is a collaboration platform used by millions of organizations worldwide. Widespread adoption of OneDrive by businesses also means there is an increase in risk of data loss due to a wide variety of reasons.

As per their terms of service, Microsoft is not responsible for backing up your OneDrive data and they recommend using a third-party cloud backup solution for backing up your data. Don’t take our word for it; here is an extract from their Services Agreement (Section 6.b).

We strive to keep the Services up and running; however, all online services suffer occasional disruptions and outages, and Microsoft is not liable for any disruption or loss you may suffer as a result. In the event of an outage, you may not be able to retrieve Your Content or Data that you’ve stored. We recommend that you regularly backup Your Content and Data that you store on the Services or store using Third-Party Apps and Services.

This article explores six different options available to backup OneDrive for business.

1. Backup OneDrive to external drive

It is possible to manually backup OneDrive for Business files to an external computer/hard drive to keep them secure in case your Microsoft 365 account is compromised. Follow the below steps to back up your OneDrive files to a computer/hard drive:

1.1. How to backup OneDrive to external drive

Follow the below steps to back up your OneDrive files to an external drive or computer:

Step 1: Log in to your Microsoft 365 account and go to OneDrive. Select the files you need to back up. You can also select all the files by clicking on the toggle selection for all items.

Step 2: Click on the three dots beside the filename and select Download or click on the Download button at the top.

This will download the selected files to your device. The downloaded files can further be copied to an external hard drive. 

1.2. Limitations of OneDrive backup to an external drive

  • Time-consuming: Large volumes of data will take several hours or days to download. It is better to use an automated backup solution.

  • Human error: Since the process is done manually, there is a high possibility that you might forget to download new or updated files.

  • Since the backup copy is stored physically, you will lose your data if something happens to the computer or external drive.

  • Lack of restoration capabilities: In case of a data loss incident, restoring files is going to be a tedious process, since you will have to manually upload all the files to OneDrive.

  • Sharing permissions are not retained.

2. Backup OneDrive for Business using OneDrive Sync Client

The OneDrive Sync Client is an application that you install on Windows that lets you sync selected local folders to OneDrive and vice versa. It can be used to: 

1. Download OneDrive data to a local machine 

2. Upload files on the local machine to OneDrive 

The application is mainly used to transfer files easily between the cloud and a local machine, but it can also be used as a backup tool for creating a copy of your data. 

2.1. How to set up OneDrive Sync Client

To set up OneDrive Sync Client, follow the below steps:

  • Step 1: Click on the Cloud icon on your desktop and click on Sign in to sign in to OneDrive with your Microsoft 365 credentials. Enter your Microsoft 365 email address and click Sign in.

  • Step 4: Once your files are synced, click on the OneDrive icon in your taskbar and click on the Settings option.

click on Settings
  • Step 5: Under Sync and backup, choose the required settings.

choose sync settings
  • Step 6: In the Account tab, click on the Choose folders button to choose the folders for syncing with the local machine. Select the required folders and click OK.

backup onedrive - choose folders to sync

All the selected OneDrive folders will be available on the desktop. However, the files will be in sync with OneDrive; any deletion in OneDrive will be reflected on the desktop, erasing the backed-up data. 
To create a backup, copy all the downloaded files to another folder on the desktop or to an external hard drive. 
Though the Desktop Sync Client can be used as a backup, relying on it completely could be risky, as local machines are prone to crashes or malware attacks. 

2.2. Limitations of OneDrive backup using Sync Client

  • Infrequent backups: Since the process of taking the backup is manual, creating consistent and regular backups will become a challenge.

  • Limited storage: To manage your storage space, you will be forced to delete older files that are of less importance.

  • High risk: Data stored on local devices can be lost due to hardware failures or ransomware attacks.

  • Possibility of data loss: If a file is lost between two backup processes, it cannot be restored.

  • Unreliability: Synchronization in OneDrive cannot be considered as a reliable alternative to backup. If you delete data from your computer, the data is also removed from the cloud. To create a backup, you will have to manually copy all the files to another folder or to an external drive.

  • Responsibility on end users: This approach is applicable only if individual users take responsibility for backing up their data. An administrator cannot manage backups for individual users.

3. Backup OneDrive for Business using native Microsoft 365 retention tools

Native Microsoft retention tools such as retention policies or labels and eDiscovery can be used to retain OneDrive data beyond the default OneDrive retention. Administrators can also use native retention tools to back up their organization’s OneDrive data.

3.1. How to backup OneDrive for Business using Microsoft 365 retention policy and retention labels

A retention policy is used to assign retention settings at a container level, that is, to a OneDrive account, whereas a retention label is used to assign retention settings at an item level. For example, if all the files in a OneDrive account need to be retained for ten years, it is easier to use a retention policy on the OneDrive account than to apply the same retention label on all the files in that account. However, if only some files in that account need to be retained for five years, then retention labels must be applied at a file level.  

To learn more about Microsoft 365 retention policies and labels, read our in-depth guide: Microsoft 365 Retention Policy and Retention Label: A Complete Guide 

3.1.1. How to create a retention policy for OneDrive for Business

    protipPro tip

    Retained files are stored in the Preservation Hold Library, and data in the Preservation Hold Library counts against your SharePoint storage quota. The total SharePoint storage limit per organization is set at 1TB plus 10GB x the number of licensed Microsoft 365 users in your tenant. If you exceed the limit, you will have to purchase additional storage priced at $200/month/TB. To save on storage costs, you can opt for a third-party backup solution, like SysCloud.

    3.1.2. How to create a retention label for OneDrive for Business

    Note: To create and configure retention labels, one needs to be a global administrator or a compliance administrator.

    3.1.4. Limitations of using retention policies and labels as a OneDrive backup solution

    • Retained data counts towards your Microsoft 365 storage quota, which is limited for each user. If you delete data to stay within the storage limit, it can't be restored later. Microsoft keeps full versions of all modified or deleted data (without incremental backups) which can lead to reaching storage limits more quickly.

    • Unlike third-party cloud backup tools, native retention methods lack automated recovery features. If data is lost, retained data can only be exported offline and restored manually, which can be a time-consuming process - especially for large amounts of data.

    • If the Microsoft 365 account falls victim to a ransomware attack and becomes encrypted, so will all the data retained.

    • Microsoft does not retain data belonging to deleted user accounts. To retain this data, you will need to maintain the user licenses and continue paying for them.

    • Retention policies and legal holds are part of the Compliance Center which is only available in senior E3/E5 plans that are more expensive than Microsoft (Office) 365 Business plans.

    • Older versions of files cannot be retained. Only the most recent version of a document is preserved.

    • Data cannot be restored from one user account to another. If you have a user leaving the company, you need to manually export the user’s data and import it to another account, which will take a significant amount of manual effort and time.

    3.2. How to backup OneDrive for Business using Microsoft eDiscovery

    Electronic discovery or eDiscovery in Microsoft 365 is used to search and export content in Exchange Online, OneDrive for Business, SharePoint Online, Microsoft Teams, Microsoft 365 Groups, and Yammer. It is also used to preserve data for compliance and litigation purposes. eDiscovery can also be used as a backup solution for your OneDrive for Business data.

    3.2.1. How to create an eDiscovery hold for OneDrive for Business

    Note: To create a hold in Microsoft 365, one needs to be a global administrator or compliance administrator. 

    Licensing requirements: 

    eDiscovery (Standard) (formerly named Core eDiscovery): Exchange Online Plan 2, Exchange Online Archiving, SharePoint Online Plan 2, Microsoft 365 Business Premium (Exchange only), Microsoft 365 E5/A5/G5/E3/A3/G3, Office 365 E5/A5/G5/E3/A3/G3, F5 Compliance, and F5 Security & Compliance. 
    eDiscovery (Premium) (formerly named Advanced eDiscovery): Microsoft 365 E5/A5/F5/G5, Microsoft 365 E5/A5/F5/G5 Compliance, Microsoft 365 E5/A5/F5/G5 eDiscovery and Audit, and Office 365 E5/A5/G5.

    protipPro tip

    eDiscovery hold is only available in Microsoft 365 Enterprise plans, which cost $32/user/month and $57/user/month respectively. To save on licensing costs, you can opt for third-party cloud backup solutions like SysCloud.

    3.2.2. Limitations of OneDrive backup using eDiscovery

    • eDiscovery feature is available only for organizations with Microsoft 365 Enterprise E3 or E5 plans, which are more expensive than Microsoft (Office) 365 Business plans. 

    • If a ransomware attack affects a Microsoft 365 account, all the data that is on legal hold will also get encrypted.

    • Each user has a limited amount of storage available, and once data is deleted to free up space, it cannot be recovered. Additionally, eDiscovery holds cannot be used to delete unimportant data (unlike retention policies), which can lead to an exponential increase in storage needs and costs over time.

    • Older versions of files cannot be retained. Only the most recent version of a document is preserved.

    • Data belonging to deleted user accounts is not retained, so if you need to keep data of employees who have left the company, you must continue paying for their user licenses.

    • Data cannot be restored from one user account to another. If a user leaves the company, their data must be manually exported and imported into another account, which is a time-consuming process.

    protipPro tip

    SysCloud's cross-user restore functionality enables effortless data restoration to a different user account, saving significant time and manual effort. This feature is particularly useful when dealing with departing employees.

    4. Backup OneDrive for Business Using OneDrive for Business API

    The OneDrive for Business API consists of a series of REST-based endpoints that developers can utilize to build applications that interact with OneDrive for Business. This API allows you to access, manage, and manipulate files and folders stored in OneDrive for Business programmatically. By leveraging this API, you can create custom backup solutions tailored to your organization's specific needs. 

    Prerequisites: 

  • Administrator access to your organization's Azure Active Directory (Azure AD) 
  • Familiarity with programming languages such as Python, JavaScript, or C# 
  • 4.1.1. Registering Your Application with Azure Active Directory

    To use the OneDrive for Business API, you first need to register your application with Azure AD. This process grants your application the required permissions to access your organization's OneDrive for Business data.  
    To register your application with Azure AD, follow the below steps: 

    • Step 1:  Sign into the Azure portal: https://portal.azure.com/

    • Step 2: Navigate to Azure Active Directory > App registrations

    • Step 3: Click New registration and fill in the required details, including the application name and redirect URI. 

    • Step 4: Under Supported account types, select Accounts in this organizational directory only.

    • Step 5: Once the registration is complete, note the Application (client) ID and Directory (tenant) ID for future use.

    4.1.2. Configuring API Permissions

    After registering your application, you need to configure the API permissions to access OneDrive for Business. To configure the API permissions to access OneDrive for Business, follow the below steps:

    • Step 1: In the Azure portal, navigate to App registrations and select your registered application.

    • Step 2: Click API permissions > Add a permission.

    • Step 3: Choose Microsoft Graph> Delegated permissions

    • Step 4: Add the following permissions: "Files.Read.All" and "Files.ReadWrite.All." 

    • Step 5: Click Add permissions to save your changes.

    4.1.3. Acquiring an Access Token

    To make API calls, your application will need an access token. This token is used to authenticate and authorize your application to access the OneDrive for Business API.  
    To obtain an access token, follow the below steps: 

    • Step 1: Set up an OAuth 2.0 authorization flow to obtain an authorization code. 

    • Step 2: Exchange the authorization code for an access token by making a POST request to the Azure AD token endpoint. You'll need the client ID, tenant ID, and client secret obtained during app registration.

    4.1.4. Creating a Custom Backup Solution

    With the access token in hand, you can now interact with OneDrive for Business API to create a custom backup solution. Follow the below steps:

    • Step 1: Retrieve a list of all files and folders stored in your organization's OneDrive for Business by making a GET request to the following endpoint: https://graph.microsoft.com/v1.0/me/drive/root/children

    • Step 2: Loop through the list and download each file using the API's download endpoint: https://graph.microsoft.com/v1.0/me/drive/items/{item-id}/content 

    • Step 3: Store the downloaded files in your chosen backup destination, such as a separate cloud storage service, a local server, or an off-site data center. 

    • Step 4: Maintain the original folder structure and metadata, including file versions and timestamps, during the backup process to ensure data integrity and easy restoration. 

    • Step 5: Implement error handling to manage cases where a file download or upload fails. This will involve logging the error and retrying as required. 

    • Step 6: Schedule the backup process to run periodically, either through a cron job or a task scheduler, depending on your platform. This ensures that your organization's data is continuously backed up and protected.

    • Step 7: Implement a notification system to inform administrators about backup successes, failures, or other issues that may arise during the process.

    4.1.5. Restoring Backed Up Data

    In the event of data loss or corruption, your custom backup solution should provide an efficient way to restore your OneDrive for Business data. Follow the below steps:

    • Step 1: Identify the files and folders that need to be restored from your backup storage.

    • Step 2:  Use the OneDrive for Business API to create or select the target folder for restored files: https://graph.microsoft.com/v1.0/me/drive/root/children 

    • Step 3:  Upload the backed-up files to the appropriate folders in your organization's OneDrive for Business using the API's upload endpoint: https://graph.microsoft.com/v1.0/me/drive/items/{parent-item-id}/children 

    • Step 4: Restore metadata, such as file versions and timestamps, to ensure data integrity.

    • Step 5: Verify that the restored files are accessible and functioning as expected.

    4.2. Limitations of OneDrive backup using OneDrive API

    • API rate limits: Microsoft imposes rate limits on API requests to prevent abuse and ensure fair usage. This may slow down your backup process, especially for large organizations with massive amounts of data.

    • Handling large files: The OneDrive API supports uploading and downloading large files, but it requires using specific methods (like creating upload sessions) that may add complexity to your backup solution.

    • Complex setup: Implementing a custom OneDrive API backup solution requires good understanding of the API and OAuth 2.0 authentication, and coding expertise, making it unsuitable for organizations lacking dedicated developers.

    • Maintenance: A custom backup solution built on the OneDrive API will require ongoing maintenance to address changes in the API, handle new features, and fix potential bugs.

    • Backup storage: Managing and securing the backup storage location may involve additional cost.

    • Manual restoration: In case of data loss or corruption, you may need to manually restore the files from the backup, which can be time-consuming and prone to errors.

    Note: These limitations may vary depending on your organization's specific needs and the complexity of your custom backup solution.

    5. Backup OneDrive for Business using third-party cloud backup tools

    Unlike the native Microsoft retention tools that are not designed for backup and restore, third-party cloud backup applications like SysCloud serve this purpose better.  

    5.1. Why should you use third-party cloud backup software for OneDrive backup?

    Using a cloud backup application to secure your OneDrive for Business data comes with its own set of advantages:

    • Effortless backup: Users can take customized backups to effortlessly backup whatever that’s necessary.

    • Incremental backup: No duplication of backup data; after the initial backup, only newly added data and modified data are backed up.

    • Automatic/scheduled backup: Take regular backups at a set frequency, so that you don’t miss out any important files.

    • Easy data retrieval: Even if an account is permanently deleted, a specific user’s data will be available in the backup application and can be restored easily in just a few clicks.

    • Better storage space management: Set retention periods and extensions to avoid backing up unnecessary files.

    • Regular activity reports: Get granular reports of all the activities in the backup account.

    5.2. SysCloud backup for Microsoft 365

    SysCloud is a leading third-party cloud backup application that offers a fully automated backup and restore solution for all Microsoft 365 apps, including OneDrive

    Using SysCloud, businesses can easily back up OneDrive data for all their domains and restore it in just a few clicks.

    • Auto-backup is turned on by default for all the apps. You can choose to turn it off only for SharePoint Sites and Teams, by checking the OFF box under Auto-backup.

    • Snapshot-level retention is available only for OneDrive. All other apps have item-level retention only. 

    • If you want the items retained only for a certain period of time, uncheck the box under Retention period and specify the number of days, months, or years for which you want the items retained. 

    • You can also choose to exclude certain file types or file sizes in OneDrive, and Deleted Items or Junk folder in Outlook. Click the pencil icon beside the app name under Exclusions and specify the desired exclusions. 

    select apps to be backed up

    Note: If you have a job with a user-level app [Contacts, Calendars, Outlook, OneDrive], at least one user should be selected in the Scope column.

    • Step 10: Click Start backup to back up your selected scope.

    Frequently asked questions on OneDrive backup

    • Should I back up OneDrive for Business?

    Yes, you should back up your OneDrive for Business to ensure the security of your mission-critical data.  In addition to the fact that Microsoft is not responsible for backing up your OneDrive data, here are seven more reasons why businesses should back up their OneDrive data: 

    - Data loss from ransomware attacks: In the event of a ransomware attack, OneDrive users who do not have a backup could lose critical data. 

    - User errors:  70 percent of data loss incidents are caused by accidental deletions. These can occur when employees in your organization: 

    (a) accidentally delete important files while trying to free up storage space 

    (b) end up removing the original version of a file while trying to get rid of duplicates  Such errors are hard to prevent and it would be impossible to restore the data past the default retention period

    - OneDrive sync feature: Due to OneDrive sync feature, if a malware infects a local machine – unless the sync is turned off – it could be synced immediately, locking all the OneDrive data on the cloud. 

    - Internal threats: A disgruntled employee could permanently delete critical business data. 

    - SaaS outages and shutdown: If Microsoft suffers an outage, data could become temporarily unavailable, disrupting business continuity. Backing up your OneDrive data can help you access them even if OneDrive is not available. 

    - Limitations of native retention settings: The native retention settings offered by Microsoft do not serve as an effective data recovery option. This is because the deleted files are: 

    (a) only retained for 93 days from the time you delete them (unless you apply retention labels/policies or eDiscovery holds), beyond which they are permanently lost.
    (b) stored along with your live account data. In the event of a ransomware attack, all your Microsoft 365 data is compromised, including the retention copies. Having an independent backup of your data stored off-site is an effective bulwark against such data loss incidents. 

    - Legal compliance and litigation purposes: Most companies are required to comply with several state and federal regulations. A backup strategy can help in supporting compliance requirements.  

    OneDrive for Business retention policy 

    - In OneDrive for Business, items are retained for 93 days from the time you delete them from their original location. They stay in the site Recycle Bin (first-stage Recycle Bin) the entire time unless someone deletes them from there or empties the Recycle Bin. In that case, the items go to the site collection Recycle Bin (second-stage Recycle Bin) where they stay for the remaining number of days. 
    - If the site collection Recycle Bin exceeds its quota, it will automatically start purging the oldest items even before the 93-day retention period is up. 
    - All OneDrive for Business users have control of their first-stage Recycle Bin but only the administrator can access and restore files from the second-stage Recycle Bin.   

    • Can you use OneDrive as a backup solution?

    Yes, you can use OneDrive as a backup solution. Here is how you can do it:

    1. Select the cloud icon in the Windows notification area.

    4. Select the folders that you want to back up. Click Start backup.

    Frequently Asked Questions on OneDrive Backup- Q A 4

    However, using OneDrive for Business as a backup solution may not be ideal due to the following reasons:

    1. It is not an admin-managed solution. The administrator cannot manage backup for individual users.

    2. If the files on your PC are infected with ransomware, it can potentially infect all the OneDrive data on the cloud as well due to the OneDrive sync feature.

    3. If Microsoft suffers an outage, OneDrive data could become temporarily unavailable, disrupting business continuity.

    • What's the difference between OneDrive Sync and OneDrive backup?

    Backup is done to keep a copy of your files at another location to prevent data loss if files are deleted or corrupted at the source location. However, sync is designed to keep the same files at different locations, meaning that if your files are deleted from the source, the ones at the destination will also get lost.  
    Thus, if you want to protect your data from accidental deletions or data corruption, backup is the suitable option for you. You can consider sync if you want access to your files on different devices. 

    • Does Microsoft back up OneDrive?

    No, Microsoft doesn’t back up your OneDrive data.  It is clearly stated in their terms of service that they are not responsible for any data loss due to negligence or malicious activities, and they recommend backing up your Microsoft 365 data including OneDrive files and folders using third-party apps.

    • Is OneDrive secure?

    Yes, OneDrive for Business is secure. OneDrive files are protected both in transit and at rest. Data in transit is protected using Transport Layer Security (TLS) encryption. Data at rest is encrypted with unique AES256 keys. These unique keys are encrypted with a set of master keys that are stored in the Azure Key Vault. Learn more about how OneDrive safeguards your data in the cloud.

    • Are OneDrive files stored locally?
