Rotation-aware drive pools
Local USB or network shares. Each drive keeps its own independent backup chain, so weekly swaps just work. Plug a drive in and the backup runs on insert.
Backup for managed service providers
Ressor is backup software built for MSPs from the ground up. Encrypted file-level and bare-metal image backup for Windows fleets, rotation-aware drive pools, and a multi-tenant portal that tells you the moment something needs attention.
30-day pilot for up to 10 machines. No card required. Agents talk outbound only.

What you get
Local USB or network shares. Each drive keeps its own independent backup chain, so weekly swaps just work. Plug a drive in and the backup runs on insert.
Encrypted, deduplicated file-level backup plus full Windows images on local and cloud storage. Restore one file or stage a whole machine image from the portal.
Define a backup policy once and assign it to a machine, a group, or a whole client. Nearest assignment wins. No per-machine config files to babysit.
One command with a site token enrolls a machine, pulls its policy, and starts the schedule. New PC at a client site is protected in minutes.
Stale rotation drives and machines that go quiet get flagged on the dashboard and emailed to you. Agent status is also a plain file your RMM can check.
Microsoft 365 single sign-on, strict tenant isolation in the portal, outbound-only agents, and configs encrypted at rest. Restores are drilled, not assumed.
How it works
Install the agent and run one command with your site's token. The machine appears in your portal under the right client.
Pick a policy set in the portal. The agent pulls it, schedules its jobs, and hot-reloads whenever you change it. Nothing to touch on the endpoint.
Every client's machines, jobs, storage, and alerts on one dashboard. Restore files or stage an offline device's cloud image onto a USB drive from the portal.
Under the hood
Ressor does not reinvent storage. File-level backup runs on kopia, an open-source engine with encryption and deduplication built in. Bare-metal images use Windows' own imaging, so a machine restores from the standard Windows recovery environment with no vendor boot disk. Our code is the part that makes it manageable at fleet scale: rotation, policies, enrollment, alerting, and the portal.
Every claim on this page is backed by a drill we actually ran, including full bare-metal restores to a blank disk.
Pilot program
Start a 30-day pilot immediately with your Microsoft work account. It includes the full portal and up to 10 protected machines, with no card required.
