Database backup that
proves it worked.
Scheduled, encrypted, verified backups for SQL Server, MySQL, MariaDB and PostgreSQL — running as a Windows service on your own hardware. Every archive is re-read, checksummed and test-restored, so the first time you find out a backup is good is not the day you need it.
No subscription. Perpetual licence · Lifetime updates · 14-day money-back guarantee
Most backups fail silently
A scheduled task that writes a file is not a backup strategy. It is a folder full of assumptions. LeoCore removes the three assumptions that cost people their data.
“It ran, so it worked”
An exit code of zero says the tool finished, not that the archive is readable. LeoCore re-reads every archive after writing it, verifies each entry's CRC and AES authentication tag, and checks the engine's own trailer to confirm the dump is complete.
“We can restore it”
Nobody knows until they try. Datacenter runs scheduled restore drills — it restores the backup into a scratch database, runs a validation query you choose, then tears it down, and tells you the moment a drill fails.
“Ransomware can't reach it”
If your backup share is writable by the server it protects, it is part of the blast radius. Datacenter writes to S3 Object Lock and Azure immutable blobs — storage that physically refuses deletion until the retention period expires.
Everything a production database needs
Built for the people who get the call at 2am — and for the auditor who asks to see the evidence three months later.
Full, differential & log backups
Native BACKUP for SQL Server, mysqldump with binlog capture for
MySQL, pg_dump custom format for PostgreSQL. Independent schedules per type.
Point-in-time recovery
Pick any moment on a visual timeline. LeoCore resolves the full → differential → log chain, checks LSN continuity before it starts, and refuses a restore it cannot complete.
AES-256 encrypted archives
WinZip AE-2 encryption with a per-archive key — in every edition, including the free one. Standard Zip64 container, so a copy opens in 7-Zip on any machine.
13 storage destinations
Local, network share, FTP/FTPS/SFTP, Amazon S3, S3-compatible, Backblaze B2, Wasabi, Azure Blob, Google Drive, Dropbox, OneDrive, OneDrive for Business, Box, Yandex.Disk.
Immutable, ransomware-proof copies
S3 Object Lock in governance or compliance mode, Azure immutable blobs, append-only destinations. Backups that even a domain admin's compromised account cannot erase.
Automated restore drills
Restore into a scratch database on a schedule, run your validation query, drop it, and email the result. Proof of recoverability, on a timetable, without a human.
GFS retention with chain safety
Grandfather-father-son daily/weekly/monthly/yearly rules. LeoCore will never delete a full backup that a differential or log still depends on — the chain is checked first.
Runs as a Windows service
Unattended, signed-out, across reboots. Server Core supported. Runs under a gMSA or a dedicated service account with only the privileges it needs.
Email alerts without a password
Four delivery routes that never ask for your mailbox password — including local relay and app-specific tokens. Success digests, or failures only. Your choice.
Logs that name the file
Every run records the archive path, its size, the compression ratio, the SHA-256, each destination it reached — and on failure, the complete error, not a code.
Auto-discovery
LeoCore finds your installed SQL Server, MySQL and PostgreSQL instances and their command
line tools on first run. No hunting for bin folders.
Nothing phones home
No telemetry, no analytics, no account required to back up. Credentials are sealed with Windows DPAPI, bound to the machine, and never leave it.
Three editions, priced by databases
Pick the tier by how many databases you protect. Every edition encrypts, verifies and restores without limits — the paid tiers add scale, unattended operation and compliance.

A backup your attacker can't delete
Modern ransomware hunts backups first. If the account that can write your backups can also delete them, you do not have a recovery plan — you have a second copy in the blast radius.
Object Lock
Write to Amazon S3 or any S3-compatible store in governance or compliance mode. Once written, the object cannot be overwritten or deleted until its retention date — not by you, not by root, not by an attacker with your keys.
Azure immutable blobs
Time-based retention policies on Azure Blob Storage, applied per archive, enforced by Azure itself rather than by our software.
Append-only credentials
Give LeoCore keys that can create objects but not delete them. Retention is then applied by a separate, tightly-scoped identity — so a compromised server cannot prune history.
Protected in about four minutes
Install
Solo from the Microsoft Store, Server and Datacenter from the installer here. The paid editions set up the Windows service during install — nothing to configure by hand.
Connect
LeoCore finds your local SQL Server, MySQL and PostgreSQL instances and their tools automatically. Confirm the credentials and pick your databases.
Schedule & store
Choose a cadence — hourly upwards — a retention rule, and one or more destinations. The plan preview shows exactly when the next runs will fire.
Verify
Turn on restore drills and email alerts. From then on, LeoCore proves the backup is restorable on a schedule and tells you the moment it isn't.
One payment. Per server. For ever.
Comparable Windows database-backup tools charge $39 for five databases and $129 for the unlimited tier — several of them annually. LeoCore matches the feature set and undercuts the price, with no renewal, ever.

Your backups are yours
Restore is never gated by a licence — in every edition, for any archive, for ever. If your licence lapses, backups keep running and every archive you already hold stays fully restorable. Archives are standard Zip64 with AES-256, readable by 7-Zip, so even without LeoCore installed your data is reachable.
A backup tool that holds your data hostage is not a backup tool. We will not build one.
Frequently asked
Is this really a one-time payment?
Yes. One payment, one server, perpetual licence, lifetime updates. There is no renewal and no expiry date. We do not sell subscriptions for this product.
How are databases counted?
Across every job on the machine, not per job. If you back up three databases in one job and two in another, that is five — which is exactly the Server edition. Counting per job would make the limit meaningless, so we do not.
What exactly is a “server” for licensing?
One licence covers one Windows machine running LeoCore, regardless of how many database instances it connects to. If you back up three SQL Server instances from one machine, that is one licence.
Can I upgrade from Server to Datacenter later?
Yes, and you only pay the difference. Email support@seksolution.com with your licence key and we will send an upgrade link.
Does it work on Windows Server Core and in air-gapped networks?
Yes to both. The paid editions run as a service on Server Core with no desktop. For air-gapped machines there is an offline activation flow: you copy a machine fingerprint from the app, paste it into a form here, and paste the signed licence back. After that the app never needs the internet again — licences are verified with a signature, not a lookup.
What happens if my licence check fails or the server is offline?
Backups keep running. A notice appears in the app, and only after a 30-day grace period do new jobs fall back to Solo limits. Existing jobs continue and restore is never affected. We are not going to stop protecting your data over a network hiccup.
Can I move a licence to a different server?
Yes. Release the seat in the app, then activate on the new machine. Hardware replacement and migrations are expected, not penalised.
Why is Solo on the Microsoft Store but the paid editions aren't?
Store-packaged apps cannot install a Windows service, which the paid editions need in order to run unattended while nobody is signed in. Solo fits the Store model well; Server and Datacenter ship as a normal signed installer from this site.
Where is my data sent?
Only to the destinations you configure. LeoCore has no telemetry and no analytics, and database credentials are sealed with Windows DPAPI, bound to that machine, and never transmitted anywhere — including to us.
Do you offer a trial of the paid editions?
Solo is free for ever and is a real product, not a crippled demo. Beyond that, the 14-day money-back guarantee is the trial: buy it, run it against your real workload, and if it does not earn its place, email support@seksolution.com for a full refund.
