Many small businesses still keep their shared files on a server in a closet: a mapped drive letter everyone knows. If you already pay for Microsoft 365, you also have SharePoint Online. Here is how the two compare, and how to decide.
Access from anywhere
A file server is easiest to reach from the office. Remote access usually means a VPN, which adds setup, support and another thing to secure. SharePoint files are available from any device through the browser, Teams or the OneDrive sync app, with the same sign-in and MFA as the rest of Microsoft 365.
Security and permissions
File servers rely on folder permissions that tend to sprawl over the years. SharePoint uses site and library permissions tied to Microsoft 365 accounts, so access ends when an account is disabled. It also brings sharing controls, audit logs and, on Business Premium, sensitivity labels and data loss prevention.
Collaboration
On a file server, two people opening the same spreadsheet usually means one gets a read-only copy. SharePoint supports real-time co-authoring in Word, Excel and PowerPoint, version history, and links that share a file without emailing copies.
Cost
A server means hardware, a Windows Server license, backup, power, cooling, patching and eventual replacement. SharePoint storage comes with most Microsoft 365 business plans. Very large file sets may need extra storage, so check how much you have before you move.
Backup and recovery
A server needs its own backup, ideally with an offsite copy. SharePoint keeps deleted files in a recycle bin for 93 days and offers version history, but an independent Microsoft 365 backup is still recommended for ransomware and late-discovered deletions.
When a file server still makes sense
Even then, many businesses move general documents to SharePoint and keep only the specialized data local.
Planning a move
How we help
Our fixed-fee SharePoint Online engagement reviews your current sites, permissions and file structure and produces a redesign and migration plan. Moving the files themselves, from a file server or another cloud service, is quoted separately as a fixed-fee project, so you know the cost before work starts.
Common questions
Can SharePoint replace a file server?
For most office documents, yes. Exceptions include applications that require a local file share and very large files used over slow connections.
Is SharePoint more secure than a file server?
It can be. Access is tied to Microsoft 365 accounts with MFA, sharing can be controlled and audited, and there is no server to patch. Good permission design still matters.
Does SharePoint back up my files?
SharePoint keeps deleted files for 93 days and keeps version history, but it is not an independent backup. We recommend a separate Microsoft 365 backup.
How long does a SharePoint migration take?
It depends on data volume, permissions and how much cleanup is needed. We provide a written plan and fixed-fee quote before any move begins.
