Backup that stays yours

Managed backup for business

Your backups belong in your own storage.

Caryvane backs up the machines you look after and writes them straight into storage you already own and control — your S3 bucket, your Azure account, your SFTP server, your NAS. No vendor lock on the one copy of your data that matters.

What it does

Machines, clouds, mailboxes — and an assistant that can drive it.

Most jobs run on an agent installed on the machine. A cloud-to-cloud job can do the same, or run on a hosted worker instead — set per job, so you decide whether the data passes through your own hardware or never touches it.

File backup

Scheduled or continuous, to whichever storage you have pointed it at.

  • Full and incremental runs
  • Real-time watching for changed files
  • Version history and retention
  • Restore to the original path or elsewhere
  • Scripts before and after a run
  • On Windows, files that are open and locked are still captured

Cloud drive

Mount object storage as an ordinary drive and work from it directly.

  • Files appear in Explorer and Finder, and open in any application
  • Fetched on demand rather than synced wholesale
  • Local cache, so what you have opened stays quick
  • Files far larger than the disk they appear on
  • Writes queue and upload in the background

AI integration

Ask an assistant about your backups, or have it run one — from Claude, ChatGPT or VS Code.

  • An MCP server for Claude and VS Code Copilot
  • A Custom GPT Action for ChatGPT
  • Personal keys, issued and revoked by each user
  • Four permission tiers, from read-only upward
  • Read the dashboard, jobs, agents and run history
  • Start or cancel a run; create jobs; mount a drive

Cloud to cloud

Back up one provider straight into another, and choose what the data passes through.

  • Any supported storage as the source, any as the destination
  • Azure Blob to Amazon S3, S3 to SFTP, SharePoint to a NAS
  • Run it on your own hardware, or on a hosted worker — per job
  • Whole containers or a single prefix within one
  • Same schedules, retention and version history as any other job

Microsoft 365

Mail, OneDrive and SharePoint copied out to storage you hold.

  • Incremental by change token, not a full sweep each time
  • Archive older mail out of the mailbox
  • Restore individual items or whole mailboxes
  • Runs from the same console as everything else

Eleven, at either end

Every one of these can be the source, or the destination.

Caryvane holds no copy of your data and sells you no storage. You supply the credentials to somewhere you already trust, and the backups land there in a form you can read without us. The same list works in both directions, so a job can read from one of these and write to another.

Where it runs

Windows, macOS and Linux, from one console.

The agent is the same product on each, and the differences are the ones the operating systems impose rather than ones we chose.

PlatformBackupCloud driveInstalls as
Windows11 and Server Yescaptures files that are open and in use Yes MSI, silent install supported
macOS26 and later, Apple silicon and Intel Yes Yes Signed and notarised .pkg
Linuxx86-64 and arm64 Yes Yes .deb and .rpm, systemd service

Administering it

One console for every machine you look after.

Agents enrol with a deployment token, so a machine can be set up without anyone sitting in front of it. From there they check in, take their jobs, report what happened and update themselves.

  • Unattended enrolment for mass deployment
  • Per-machine job history, with the errors kept
  • Browse and restore from the console
  • Agents update themselves; no rollout to chase

Common questions

The things people ask first.

Where are my backups actually stored?

In storage you already own and control. You give Caryvane credentials for an Amazon S3 bucket, an Azure Blob container, an SFTP server, an SMB share or a NAS, and the backups are written there. Caryvane keeps no copy of your data and sells you no storage, so you can read your backups without us.

Can I manage backups from Claude or ChatGPT?

Yes. Caryvane runs an MCP server for Claude and VS Code Copilot, and exposes a Custom GPT Action for ChatGPT. Each user issues their own key and can revoke it, and the key carries one of four permission tiers: read-only, read plus start and cancel runs, plus create and edit jobs, or full including deletes. An assistant can be given exactly as much as you want it to have and no more.

Can I back up one cloud provider into another?

Yes. A cloud-to-cloud job reads from any supported storage and writes to any other — an Azure Blob container into Amazon S3, an S3 bucket to SFTP, a SharePoint library onto a NAS. It can copy a whole container or a single prefix within one. You choose per job whether it runs on one of your own machines, so the data passes through hardware you control, or on a hosted worker so nothing of yours has to be switched on.

Which operating systems does it run on?

Windows 11 and Windows Server; macOS 26 and later on both Apple silicon and Intel; and Linux on x86-64 and arm64, packaged as .deb and .rpm. The same agent and the same console cover all three.

Can it back up Microsoft 365?

Yes. Mail, OneDrive and SharePoint are copied out to storage you hold. Runs are incremental by change token rather than a full sweep each time, older mail can be archived out of the mailbox, and individual items or whole mailboxes can be restored.

What is the cloud drive?

It mounts object storage as an ordinary drive, so files appear in Explorer or Finder and open in any application. Content is fetched on demand rather than synced wholesale, which means a drive can hold far more than the disk it appears on. Writes queue and upload in the background.

Can I restore a single file, or only a whole backup?

Either. Version history is kept according to your retention policy, and you can restore a single file from a chosen point in time, or a whole set, to the original location or somewhere else.

How many machines can one console manage?

It is built for managing many machines rather than one. Agents enrol with a deployment token so a machine can be set up without anyone in front of it, then check in, take their jobs, report results and update themselves.

Does the agent need someone to install it by hand?

No. Installation is unattended on every platform — an MSI with silent install on Windows, a signed and notarised .pkg on macOS, and .deb or .rpm packages with a systemd service on Linux.
