At the center of daily operations for medical, dental, financial, and SMB teams across Middle Tennessee is Microsoft 365. Email, OneDrive files, SharePoint sites, Teams channels—you depend on them every minute of the day.
As a security-first MSP serving healthcare and compliance-driven organizations in Middle Tennessee, we see this misunderstanding all the time. And the risk is real: one wrong click or misconfigured retention policy can wipe out months of critical business data with no way back.
Let’s clear this up.
Microsoft 365 does an excellent job with:
But Microsoft is very clear: you are responsible for your data.
This is the Shared Responsibility Model, and it applies to:
If a user deletes data—intentionally or accidentally—retention policies only help if they were configured in advance and the retention window hasn’t expired.
This poses a major compliance challenge for healthcare practices, financial institutions, and any business required to retain records for 6+ years.
Retention holds data for a window of time:
Retention manages lifecycle—it does not create a separate, immutable backup copy.
Backup Separate, Independent, Recoverable Copy
A proper Microsoft 365 backup solution provides:
That last point is huge: if your Microsoft 365 tenant is compromised, retention won’t save you—but a backup stored in an independent system will.
Healthcare and other regulated industries must prove:
HIPAA and NIST both emphasize encrypted backups, tested restores, and documented recovery procedures (aligned with HICP & NIST 800-66 guidance).
FTC Safeguards and PCI require the same—written policies + verified backup testing.
Retention alone cannot meet these requirements, because regulators expect:
So, if your practice or business relies only on retention, you are one bad click away from a compliance incident.
RPO (Recovery Point Objective)
How much data can you afford to lose?
Example:
If your RPO is 4 hours, your backup must take snapshots at least every 4 hours.
RTO (Recovery Time Objective)
How long can you afford to be down while recovering data?
Example:
If your RTO is 2 hours, your recovery plan must restore files or mailboxes within that timeframe.
Backups only matter if you can restore them.
That’s why Johnson BTS performs quarterly restore testing for compliance-heavy clients:
HIPAA, NIST, and HICP all emphasize testing, not just “having a backup”.
And too many businesses discover during a crisis that their backup:
Quarterly testing eliminates those surprises.
1. Employee deletes their entire OneDrive before leaving
Retention doesn’t cover everything—and often doesn’t apply after 30-93 days.
2. Ransomware hits a synced OneDrive folder
Sync = ransomware spread.
Backup = clean versions to restore.
3. SharePoint admin accidentally deletes a site collection
After 93 days, it’s unrecoverable without backup.
4. Global admin account compromised
Attackers often delete or corrupt retention policies.
5. Email mailbox corruption
Retention cannot restore a mailbox to a healthy point-in-time state.
6. Legal or audit requests for data from 3+ years ago
Retention is not long-term archival unless extremely custom-tailored.
These incidents are common, not rare—and retention alone does not protect you.
