Keep institutional memory
Years of customer conversations, decisions and approvals remain part of the company instead of becoming collateral damage when a server fails.
Real-time backup for Zimbra Open Source
Real-time backup for Zimbra.
Your history stays recoverable.
RayBackup continuously protects messages, changes and business history while Zimbra keeps running. No invasive hooks. No traditional backup window. Your storage, your control.
Email is not just email
It is where a surprising amount of your company history lives.
Business decisions rarely arrive as neat database rows. They arrive as conversations, approvals, attachments, agreements, questions, answers and years of context.

When a mailbox disappears, part of the company disappears with it.
Built for the people who actually run Zimbra
Keep the deployment simple. Keep control of the backup.
RayBackup is designed to run alongside Zimbra, capture changes continuously and write recovery data to storage you control.
01
Zimbra
Keeps doing its job.
02
RayBackup
Captures, organizes and verifies recovery data.
03
Your storage
Filesystem, NAS/NFS or S3-compatible storage.
No invasive hooks
No mailboxd modifications, fragile patches or product-specific storage appliance.
No storage lock-in
Use storage that makes sense for your environment and your budget.
No traditional backup window
Protection follows change instead of waiting for tonight’s scheduled job.
How it works
Capture. Protect. Verify. Recover.
Four boringly clear steps. Backup infrastructure does not become more reliable because someone gave every component a mysterious product name.
Capture
Changes are tracked continuously, reducing the gap between activity and protected recovery data.
Protect
Content and history are stored independently from the live Zimbra server.
Verify
Consistency checks help detect gaps instead of quietly turning them into tomorrow’s surprise.
Recover
Restore individual content or rebuild logically after a larger failure.
For the business
Spend less time protecting email. Have more time to run the business.
Reduce operational anxiety
Know the difference between data that was merely captured and recovery points that are actually restorable and verified.
Recover without storage lock-in
The backup repository lives in storage chosen by your team. You keep control of cost, location and operational policy.
Simplify disaster recovery
A failed Zimbra host should be a recovery job, not an archaeological expedition through old disks, scripts and half-remembered procedures.
Stop babysitting backup windows
Continuous protection and scheduled verification are designed to replace repetitive manual checks with useful recovery signals.
For the technical team
Serious recovery architecture without turning your mail server into a science project.
RayBackup is being built around source isolation, content-addressable storage, rebuildable local indexes and a repository that remains useful even after the original Zimbra host is gone.
Real-time protection
Changes are captured continuously instead of depending only on a scheduled full-backup window.
Zimbra stays Zimbra
No invasive mailboxd modifications, no patch dependency and no need to rebuild the backup architecture after every ordinary upgrade.
BYOS architecture
Write to mounted filesystems or S3-compatible storage. Keep your repository where your operational model says it belongs.
Content-addressable storage
SHA-256 based object storage supports deduplication and integrity verification without multiplying MIME content for moves, tags and flags.
Recoverable by design
The repository is designed to remain the source of truth. Local catalog data can be rebuilt instead of becoming a hidden single point of failure.
Logical point-in-time recovery
Reconstruct useful mailbox state instead of requiring a physical clone of the original server, database and internal IDs.
Step 01
Captured
The change is durably protected outside the volatile source flow.
Step 02
Restorable
The required objects have been processed into a valid recovery state.
Step 03
Verified
Recovery state has been checked for consistency against the source.
Your backup should fit your storage strategy.
RayBackup is built around BYOS. Use a simple mounted filesystem when simplicity matters, or S3-compatible object storage when stronger isolation, scale and storage-enforced immutability matter more.
Local / mounted
Filesystem
Local disks or mounted volumes for straightforward deployments.
Network storage
NAS · NFS · SMB
Keep the repository on infrastructure your team already operates.
Private object storage
S3-compatible
Use compatible platforms such as RustFS, MinIO or Ceph-based storage.
Cloud object storage
Public S3 services
Use supported S3-compatible cloud providers and keep storage separate from Zimbra.
Storage-enforced immutability
When the backend supports Object Lock, WORM or retention policies, RayBackup can use and verify those capabilities. On ordinary filesystems, integrity remains verifiable but physical immutability depends on the storage itself.
Disaster recovery
Assume the server is gone.

RayBackup repositoryAVAILABLE
A backup should not need the failed server to recover from the failed server.
RayBackup is being designed so a valid repository plus a fresh installation is enough to inspect, rebuild the local catalog and recover supported Zimbra data into a new environment.
Designed to stay simple
Install it. Point it to storage. Protect Zimbra.
One product.
Your storage.
No infrastructure circus.
Simple pricing
Pay for the size of the environment, not for storage you already own.
RayBackup uses BYOS pricing: your team provides the repository, so the subscription stays focused on the software that protects and restores Zimbra.

Join the Early Access WaitlistBuilt beyond one platform
Zimbra first. Carbonio planned.
RayBackup’s recovery core is being designed independently from the source platform. Zimbra Open Source is the first target; Carbonio support is planned as a future adapter rather than a separate backup product.
No fake “coming next week” banner. It ships when the adapter is proven.
