NinjaOne SaaS Backup (Dropsuite) vs Restow: alternative and comparison 2026
NinjaOne SaaS Backup, formerly Dropsuite, is a pure cloud service on AWS, priced per user and sold mainly through MSPs. NinjaOne completed its acquisition of Dropsuite on 2 June 2025. The service covers more of Microsoft 365 than Restow does today, and Google Workspace too.

The short answer
NinjaOne SaaS Backup fits if you want a hosted service with unlimited storage, EU data centres including Germany, and coverage for SharePoint, Teams, Google Workspace and IMAP in one place.
Restow fits if you want a one-time license with optional update years instead of a fee per seat, keep the backups on your own storage, and see a weekly proof that each backup can actually be restored.
At a glance
| Aspect | Restow | NinjaOne (Dropsuite) |
|---|---|---|
| Price model | Community free. Business €595, Service Provider €1,950, one-time, net (pre-sale until release: €476 and €1,560). Pre-sale licenses include every 1.x update; from version 1.0, a license includes 12 months of updates, then an optional update year (Business €295, Service Provider €595 net per year). No per-user fee. | Per user, recurring, storage unlimited, no ingress or egress fees. No long-term contract typically required. |
| Where it runs | Self-hosted: one Docker Compose stack on a Linux server or VM you control. | SaaS on AWS. No self-hosted option. |
| Where backups are stored | Your choice: local disk, S3-compatible object storage or NFS, in the region you pick. Immutable backups (S3 Object Lock) can be switched on per repository. | AWS regions you pick (for example Germany or Ireland). No own-storage option found. |
| Microsoft 365 coverage | Exchange Online mail, calendar, contacts; OneDrive; SharePoint Online sites (document libraries and lists, new in 0.4.0); Microsoft 365 groups (calendar and conversations, opt-in, since 0.4.5); IMAP mailboxes; Linux and macOS servers and clients (file-level agent); SMB and NFS file shares without an agent; imported mail files. No Teams chats. | Exchange incl. shared mailboxes and public folders, OneDrive, SharePoint, Groups, Teams, Entra ID; also Google Workspace and IMAP/POP3. |
| Restore testing | Weekly sampled check: data is read back through the restore path and verified against the recorded hashes. File shares are checked after every new restore point, Proxmox VE (preview) guests within minutes of every new restore point, and Proxmox VE can also boot-test restore points. | Not documented in the pages checked. |
| Source code and exit | Apache 2.0 core, Business and Service Provider modules under the Restow license terms, open documented storage format with a standalone restore tool. | Proprietary. Free self-service export as EML, PST via conversion. |
Where NinjaOne (Dropsuite) is strong
- Broad coverage: SharePoint, Teams, Entra ID, Google Workspace and IMAP/POP3.
- Unlimited storage and no ingress or egress fees.
- Choice of AWS region, including Germany.
- Free EML export and restore into other mailboxes or tenants.
- A white-label programme for qualifying resellers.
Where Restow is different
- A one-time license instead of a per-seat fee: Business €595, Service Provider €1,950; update years are optional (Business €295, Service Provider €595 net per year).
- Storage you operate or rent yourself, not a vendor's AWS account.
- A weekly sampled read-back check per mailbox, shown as recovery readiness.
- Open source core and an open storage format.
What Restow does not do (yet)
- Restow does not back up Teams chats. It backs up SharePoint Online sites since 0.4.0, without attachments of list items, site design, navigation and workflows; permissions are kept as information and never restored.
- Immutable backups (new in 0.4.0) are off until an administrator turns them on per repository. S3 Object Lock was tested against a simulated S3 service only, directories and NFS get only a deletion delay, which is not immutability, and the installation's default repository cannot be made immutable.
- In Business, the audit log viewer ships since 0.1.0 and the audit log export since 0.3.1; since 0.3.1 every edition has several administrators with roles. Sign-in with Microsoft and single sign-on (SSO) are planned, and so are four-eyes approval and a signed restore proof.
- The archive is filled by mail import with archiving and, from Business, by capture from the mailboxes (Microsoft Graph, IMAP sync), Exchange Online journal receipt and forwarded copies. Capture from the mailbox is near-time and not complete, and was tested against simulated services only.
- The automated Microsoft 365 backup and restore check against a real tenant is not active yet: check 4 of the release pipeline was skipped in every release so far; Microsoft 365 is covered by tests against a simulated Graph API.
- Licenses include no support, setup, operation or SLA.
- The server and endpoint agent runs on Linux and macOS, file-level; a Windows agent and image backup are planned.
- Restow is a beta: do not use it as your only backup.
