Every business that runs on Microsoft 365 eventually becomes deeply dependent on two platforms more than others: Microsoft Teams and SharePoint. Teams keeps your people connected through daily conversations, project channels, file sharing, and virtual meetings. SharePoint acts as the central document library where files live, are organised, and are accessed by the teams who need them most. Together, they form the digital backbone of how modern organizations actually get work done.
The problem is that a surprising number of IT teams treat these platforms as separate concerns when it comes to data protection. Some back up Teams but overlook SharePoint entirely. Others have a solid SharePoint and OneDrive backup strategy in place, but never give serious thought to what is happening inside Teams. Either way, the result is the same. There are gaps in your data protection that can turn a manageable incident into a full recovery nightmare, and those gaps rarely announce themselves until the damage is already done.
Microsoft Teams Relies on SharePoint More Than People Realize
Here is something that catches many IT professionals off guard. When someone shares a file inside a Microsoft Teams channel, that file is not actually stored inside Teams. It lives in SharePoint. Specifically, it goes into the SharePoint document library that is linked to that particular team. Every document uploaded to a channel, every file added to a Teams tab, and every shared resource your team collaborates on together sits in the SharePoint backend.
This means that if your SharePoint data gets deleted, corrupted, or hit by ransomware, those Teams files disappear along with everything else. You are not just losing a document library. You are losing everything your teams have built, shared, and worked on together inside their channel workspaces. That architectural connection is exactly why Microsoft Teams and SharePoint backup need to be treated as a single, unified concern rather than two separate line items on a backup checklist.
What Teams-Only Backup Really Covers
When a backup tool covers Teams, it typically protects chat messages, channel conversations, meeting recordings, and direct message threads. This is genuinely valuable information. A conversation thread that documents a key project decision, a meeting recording that captured an important client discussion, or a chain of messages that outlines agreed-upon terms all represent data your business cannot afford to lose without warning.
But Teams backup that does not include SharePoint is incomplete by design. You might be able to restore the conversation that referenced a file, but if SharePoint is not protected, the file itself is gone. Your channel history might survive a ransomware attack while your entire document library remains unrecoverable. The conversation exists. The work it was built around does not.
The Gap Works in Both Directions
The reverse creates equal risk. A business that maintains a strong SharePoint and OneDrive backup routine but ignores Teams conversations is operating with a significant blind spot.
Consider a compliance scenario. An employment dispute arises, and your legal team needs to produce all communications related to a specific project. The documents are in SharePoint and recoverable, but the channel discussions, real-time decisions, and context that make those documents meaningful are gone because Teams conversations were never backed up. The files exist. The story around them does not, and in a legal or regulatory setting, that missing context matters enormously.
This is precisely where M365 audit log backup becomes part of the picture. Audit logs record every action taken across your Microsoft 365 environment, who accessed what, when files were deleted, and where data was moved. Without them, reconstructing a timeline is guesswork. With them, you have a complete forensic record that supports compliance reporting, internal investigations, and any questions a regulator might ask.
Why Microsoft’s Own Tools Fall Short
Microsoft offers a basic safety net in Teams and SharePoint through the recycle bin, version history, and retention policies. These cover short-term, everyday mistakes well enough. An employee accidentally deletes a file and restores it within a day. Someone needs an older document version quickly and retrieves it with minimal fuss.
What they cannot do is protect against serious data loss events. Retention policies are not backups. They govern how long data is eligible to be kept, not how to restore it after a significant incident. A proper Microsoft 365 backup solution operates entirely outside of Microsoft’s infrastructure. It captures scheduled, point-in-time snapshots of your data and stores them in a separate environment where a ransomware attack on your live tenant cannot reach them. That separation is what makes recovery possible when native tools have already been rendered useless.
What a Complete Strategy Looks Like in Practice
Protecting Teams and SharePoint properly means treating them as connected systems that need connected coverage. Teams channel conversations need to be captured. The SharePoint document libraries behind those channels need to be included. OneDrive files, which feed into both environments regularly, need to be protected too, and the version history, metadata, and permissions structures that give your data its context need to be preserved alongside the content itself.
Recovery capability matters just as much as what is backed up. A complete Microsoft Teams and SharePoint backup strategy should allow your team to restore a single file, a particular folder, or an entire site without triggering a full system restore. Granular recovery cuts the time and disruption involved in any incident dramatically, whether the cause is a disgruntled employee, an accidental deletion, or an active cyberattack working its way through your environment.
Wrapping It Up
Microsoft Teams and SharePoint backup are not two separate problems sitting side by side. They are two sides of the same challenge, and leaving one side unprotected puts the other at risk as well.
ExchangeSavvy provides complete, unified backup coverage for Microsoft 365 environments, including Teams conversations, SharePoint document libraries, OneDrive files, and audit logs, all managed from a single platform with granular recovery and immutable storage built in. If your current strategy does not cover both platforms together with full consistency, it is not yet a complete strategy. The right time to close that gap is before something goes wrong, not after.
Frequently Asked Questions
Q1: Are Teams files stored inside Microsoft Teams or somewhere else?
Files shared in Teams channels live in SharePoint, specifically in the document library tied to that team. Backup Teams without SharePoint, and those files have no protection at all.
Q2: Does Microsoft automatically back up Teams and SharePoint data?
Microsoft keeps the service running. Recovering your data after a loss event is your responsibility. The recycle bin and retention policies help with minor mistakes, but neither replaces a proper backup.
Q3: What happens to Teams data when a team is permanently deleted?
Delete a team in Microsoft 365, and the linked SharePoint site disappears with it, files and all. Once that retention timeframe closes, the data is gone for good without an independent backup.
Q4: If my Teams and SharePoint files are backed up, why do I still need to back up M365 audit logs?
An Audit log tracks everything that happens across your Microsoft 365 environment. When anything goes wrong, they show you what exactly happened, who did it, and when. That record carries real weight in compliance audits, legal reviews, and security investigations.
Q5: Can individual items be restored without restoring an entire dataset?
They can be restored. With granular recovery, you can restore a specific file version, a deleted conversation, or an individual document library without touching other things. Most recovery needs are targeted, not sweeping. There is rarely a reason to restore an entire environment to recover one item.
