Restore without paying: your latest backup survives ransomware
Rezilva backs up your critical data immutably, keeps an isolated copy out of the attacker's reach and tests your restores before the day you need them.
Product in development: this page describes what is aimed for, not a service that is already open.
Designed to survive a compromise
Rezilva assumes the attacker has already got past upstream protections. Backups are therefore isolated, encrypted and logged so that they remain usable when everything else has fallen.
-
3-2-1-1-0 ruleThree copies, two media, one off-site, one immutable or isolated, zero verified errors.
-
Logical air gapIsolated vault, dedicated credentials, no online deletion possible.
-
Encryption by defaultRepositories are encrypted with a key you control; opening a repository in clear text requires an explicit action.
-
Tamper-proof audit logEvery backup and restore operation is traced.
What Rezilva aims for
The backup and restore engine is in development; the rest follows the roadmap.
True immutability
WORM / object-lock style retention lock on object storage.
Proven restores
Automatic restore test and restorability report.
Anomaly detection
Change rate, entropy and mass encryption spotted within backups.
Measured RPO / RTO
Recovery point and recovery time objectives defined per dataset, then measured.
Microsoft 365 backup
Backup of mail and collaboration through the Graph API.
Gap-free migration
Switch from another backup solution without losing retention.
Optional Kopilvia contextual help
Every console view offers help that knows the state of your estate. If Kopilvia is unreachable, help carries on in degraded mode, and says so.
Pricing to come
No price has been set yet. It will be published at launch, aligned with the SANTVIA galaxy offers.
Rezilva takes over where upstream stops
Each SANTVIA product remains usable on its own; together, they form a coherent sovereign suite.
Frequently asked questions
Can ransomware encrypt my Rezilva backups?
Rezilva is designed so that it cannot: backups are locked during their retention and a copy stays isolated, with credentials distinct from those of production.
How do I know I can really restore?
Rezilva tests restoration automatically and produces a restorability report. A backup that has never been restored is not considered a backup.
Where are my backups stored?
In the European Union, with a European operator. Rezilva is also designed to run on the customer's infrastructure.
What does Rezilva cover?
Files, databases and Microsoft 365 mail are the first datasets; workstations, servers and virtual machines follow the roadmap.
Is Rezilva available, and at what price?
Not yet: the product is in development and no price is set. Join the waitlist to be notified.

Three guarantees, in this order
A backup that cannot be restored is worthless. Rezilva does not just tell you a copy exists: it shows you that it is intact and that it comes back.
Immutable backup
Each backup is locked for its entire retention period: it can be neither modified nor deleted, even with a compromised administrator account.
Tested restore
Restoration is verified automatically, well before the incident. You get a restorability report, not an assumption.
Anomaly detected
A spike in modified files or mass encryption triggers an alert, and the latest healthy restore point is identified for you.
