SharePoint Backup Licensing: Complete Guide for Enterprise IT

SharePoint Online backup is the licensing conversation most organisations have backwards. They buy backup tools for SharePoint before understanding what SharePoint's native recycle bin, versioning, and retention policies already provide — then discover they've paid for overlapping capability. At the same time, 43% of organisations we've assessed have a critical SharePoint recovery gap: they can restore a deleted file but cannot restore a SharePoint site to a specific point in time before a mass deletion event. Microsoft 365 Backup closes that gap — at a cost.

SharePoint Native Recovery Capabilities (Before Paid Backup)

Before licensing external backup tools, understand what SharePoint Online's built-in recovery features already provide. Most organisations underestimate the scope of native capability and overspend on backup tools that duplicate features included in their EA.

First-Stage Recycle Bin

• Retention: 30 days (automatic)
• Access: End users (self-service restoration)
• Coverage: Files, folders, lists, list items
• Cost: $0 (included with all M365 licences)

Second-Stage Recycle Bin (Site Collection)

• Retention: Additional 93 days (total 123 days)
• Access: Site collection administrators only
• Coverage: Files, folders, lists deleted from first-stage recycle bin
• Cost: $0 (included with all M365 licences)

Version History

• Maximum versions: Up to 500 per file (configurable)
• Retention: 180 days by default (configurable to 10 years)
• Access: Any user with document access can restore previous versions
• Limitation: Does NOT restore deleted SharePoint sites or site collections
• Cost: $0 (included with all M365 licences)

Native Recovery Gap

SharePoint's native recycle bin and versioning cover >80% of accidental deletion scenarios at zero cost. However, they cannot restore:

• Deleted SharePoint site collections (recovered only via Microsoft support)
• Mass deletion events (>100 items deleted rapidly) — recovery is slow and manual
• Ransomware-encrypted sites (versions may be encrypted alongside files)
• Content corruption (overwritten files with malicious data)

For these scenarios, external backup is necessary. This is where Microsoft 365 Backup, Veeam, and third-party solutions enter the picture.

What Microsoft 365 Backup Adds for SharePoint

Microsoft 365 Backup (released in limited public preview, general availability 2026) provides point-in-time site restore capability that native features do not cover.

M365 Backup: SharePoint-Specific Features

• Point-in-time site restore: Restore an entire SharePoint site collection to a specific moment in time
• Granular restore options: Full site, subsite, document library, or individual item
• Restore window: 30 days of automated backups (taken every 10 minutes)
• Coverage: SharePoint Online only (not SharePoint Server on-premises)
• Pricing: $0.15/GB/month based on size of protected SharePoint data
• Ransomware protection: Immutable vault prevents backup deletion during active attack

SharePoint Data Volume: What Organisations Actually Pay

M365 Backup pricing is consumption-based on data size. Understanding your actual data footprint is critical for accurate cost forecasting — most organisations discover they're paying for significantly more capacity than they thought.

Typical Enterprise Data Profile

• Average per-user SharePoint consumption: 15–25GB consumed (vs 1TB allocated per user)
• 1,000-user organisation at 15GB average: 15TB × $0.15/GB = 15,000 GB × $0.15 = $2,250/month = $27,000/year
• 1,000-user organisation at 25GB average: 25TB × $0.15/GB = $3,750/month = $45,000/year

Growth Impact on 3-Year Cost

SharePoint data grows 25–35% annually as Teams adoption increases and users archive more content to SharePoint (instead of deleting).

• Year 1: $27,000 (15TB organisation)
• Year 2 (30% growth): $27,000 × 1.30 = $35,100
• Year 3 (30% growth): $35,100 × 1.30 = $45,630
• 3-year total: $107,730 for a 1,000-user organisation

SharePoint Backup Coverage Gaps in Microsoft 365 Backup

Before committing to M365 Backup, be explicit about what it does NOT cover:

Third-Party SharePoint Backup Options

If your organisation requires capabilities beyond M365 Backup (on-premises coverage, broader M365 workload bundling, deeper granularity), third-party solutions provide alternatives.

Cost Comparison: M365 Backup vs Third-Party (1,000 users)

• M365 Backup (15TB): $27,000/year (+ growth)
• Veeam Backup for M365 (1,000 users @ $3/user/month): $36,000/year (covers SharePoint, Exchange, OneDrive, Teams)
• AvePoint Cloud Backup (1,000 users @ $4/user/month): $48,000/year (SharePoint-focused granularity)

For SharePoint-only workloads, M365 Backup is cheaper. For multi-workload protection (SharePoint + Exchange + Teams + OneDrive), Veeam is more cost-effective.

Retention Policies vs Backup: A Critical Distinction

Enterprise IT often conflates retention policies with backup. They serve opposite purposes and are not substitutes.

Microsoft Purview Retention Policies

• Purpose: Preserve content for compliance (make undeletable)
• Effect: Content cannot be permanently deleted, even by administrators
• Timeframe: Indefinite (until retention expires)
• Recovery capability: None — content is preserved but not restorable to a prior state
• Ransomware protection: No — if files are encrypted, retention policy does not help restore unencrypted versions
• Cost: Included in E3/E5 or via Purview standalone licence

Backup (M365 Backup, Veeam, AvePoint)

• Purpose: Create restorable point-in-time copies for operational recovery
• Effect: Content can be restored to a specific moment (before deletion, corruption, or attack)
• Timeframe: Limited to backup retention window (M365: 30 days; third-party: configurable)
• Recovery capability: Full — restore entire sites, libraries, or individual items to prior state
• Ransomware protection: Yes — restored content is unencrypted and usable
• Cost: Separate licence (M365 Backup: $0.15/GB; Veeam/AvePoint: $2–$5/user/month)

SharePoint Backup Negotiation Strategy

Microsoft 365 Backup pricing and third-party backup licensing both offer negotiation opportunities in enterprise agreements.

M365 Backup Negotiation

• Storage tier discounts: Negotiate committed storage capacity tiers. Microsoft offers 15–25% discounts above list pricing for multi-year commitments (e.g., "$0.12/GB instead of $0.15/GB for 50TB+ committed).
• Bundling into MACC: Microsoft may propose bundling M365 Backup into MACC (Microsoft Azure Consumption Commitment). Evaluate whether this genuinely reduces total cost or simply obscures Azure spending growth.
• E5 overlap analysis: If your organisation is considering E5 for compliance features, some E5 Purview capabilities partially overlap with backup for legal hold scenarios. Negotiate which scenarios are covered by E5 licencing before adding M365 Backup.

Third-Party Backup Negotiation

• AvePoint pricing pressure: AvePoint has 20–30% discount available when facing M365 Backup competition. Explicitly mention M365 Backup in your RFP.
• Veeam bundling: If you're already licensing Veeam Backup for M365, evaluate whether adding M365 Backup creates cost duplication. Most organisations choose one or the other, not both.
• Multi-year discounts: All third-party tools offer 10–20% discounts for 3-year commitments. Lock in pricing before cost escalation.

Frequently Asked Questions

Does SharePoint Online have a built-in backup that covers ransomware attacks?

SharePoint Online's native versioning and recycle bin provide some protection against ransomware — if an attack encrypts files, previous versions (up to 500) remain accessible for 180 days. However, if a ransomware variant specifically targets SharePoint and systematically deletes versions before encryption, native protection fails. Microsoft 365 Backup's point-in-time restore at 10-minute intervals provides stronger ransomware recovery capability. For organisations with high ransomware risk, external backup is strongly recommended.

What is the SharePoint backup included with Microsoft 365 E3 or E5?

There is no automatic backup included with M365 E3 or E5. E3/E5 licences provide SharePoint versioning and the standard recycle bin, but not point-in-time site restores or automated backup. Microsoft 365 Backup is a separately licensed add-on charged at $0.15/GB/month regardless of whether you have E3 or E5. Ensure your financial model accounts for M365 Backup as an incremental cost to your EA.

How much SharePoint data does a typical 1,000-user organisation have?

Based on enterprise engagements, the typical 1,000-user organisation has 10–20TB of active SharePoint data (consumed, not allocated). This equates to $1,500–$3,000/month in M365 Backup charges at $0.15/GB. Data growth of 25–35% annually means year-3 costs are typically 70–80% higher than year-1. When budgeting for M365 Backup, explicitly model growth and include it in your 3-year financial projection.

Do SharePoint retention policies replace the need for backup?

No — they serve completely different purposes. Retention policies (via Microsoft Purview) preserve content for compliance by making it impossible to permanently delete. Backup creates restorable point-in-time copies for operational recovery. If SharePoint content is corrupted or mass-deleted within the retention window, a retention policy does not help you restore to a prior state — you need backup for that. Both are essential for enterprise data governance.

Is Veeam Backup for Microsoft 365 better than Microsoft 365 Backup for SharePoint?

For SharePoint Online specifically, both tools provide comparable point-in-time restore capability. Veeam's advantage is that a single licence covers Exchange, SharePoint, OneDrive, Teams, and Groups — making it cost-effective when you need all workloads covered. Microsoft 365 Backup charges separately per workload (GB-based). If you're already paying for Veeam Backup for M365, adding M365 Backup creates cost duplication. Evaluate your broader M365 protection needs before selecting between them.
