What BackupZit backs up
One console for every machine you run — physical, virtual and in the cloud.
Windows and Linux files
Incremental file backup, from a VSS snapshot on Windows so open files are consistent. Restore single files straight from the browser.
Whole disks and bare metal
Disk images of Windows PCs and servers and full Linux system backups, restored from a recovery ISO — also onto different hardware.
Proxmox VE
Agentless backup of VMs and containers, changed blocks only, instant recovery, replication and automatic boot tests.
VMware ESXi and vCenter
Agentless backup with changed block tracking through a proxy agent — also with the free ESXi license. Instant recovery over NFS.
Hyper-V
Agentless Hyper-V backup with resilient change tracking, restored to the same or another Hyper-V host.
Databases
SQL Server, PostgreSQL and MySQL/MariaDB with their native tools, log backups and point-in-time restore of a single database.
NAS shares
SMB and NFS shares read by any agent — nothing has to be installed on the NAS.
Microsoft 365
Exchange Online mail, calendars and contacts, OneDrive and SharePoint through Microsoft Graph with read-only permissions.
Why BackupZit
Your server, your network
Every organization runs its own console. There is no cloud service, no account with us, and nothing has to be exposed to the internet.
Built against ransomware
Immutable backups (S3 Object Lock or the write-once hardened repository), detection of backups that look like ransomware or mass deletion, automatic restore tests and a tamper-evident audit log.
Efficient on any storage
Deduplication, compression and AES-256 encryption on SFTP, S3, SMB, Azure Blob Storage, USB or local disks and the hardened repository. Backup copy jobs for the 3-2-1 rule.
Easy to run
Schedules, job chains, backup windows, RPO alerts, PDF reports, email, Slack and Teams notifications, REST API, roles, LDAP/Active Directory, SSO and signed self-updates.
In your language
The console speaks 14 languages: English, German, French, Spanish, Italian, Portuguese, Dutch, Polish, Czech, Serbian, Turkish, Russian, Chinese and Japanese.
Free, with support if you want it
Open source under the AGPLv3, with no limits on machines, VMs or storage. Commercial support comes from MaxZit, the company behind BackupZit.
How it works
- The console is a small Linux VM (2 vCPU, 2–4 GB RAM, 20 GB disk). It does not store backup data.
- Agents connect to the console — no open ports on the protected machines — and trust it by its pinned certificate fingerprint, so no public certificate authority is needed.
- With the recovery key, backups can be restored even without the console.
Running in minutes
Import the ready-made appliance — OVA for VMware, qcow2 for Proxmox/KVM, VHDX for Hyper-V — boot the appliance ISO, or install on an existing Debian, Ubuntu, AlmaLinux or Rocky Linux server:
curl -fsSL https://github.com/Max-Zit/backupzit/releases/latest/download/install.sh | sudo shThen open https://<server>:8443, sign in and add agents: an MSI for Windows, deb/rpm packages for Linux. All downloads and install options.
Frequently asked questions
Is BackupZit free?
Yes. BackupZit is free and open source under the GNU AGPLv3, with no limits on machines, VMs or storage. MaxZit offers optional commercial support.
Can BackupZit back up Proxmox VE, VMware and Hyper-V virtual machines?
Yes. Proxmox VE VMs and containers, VMware ESXi VMs (directly or through vCenter Server) and Hyper-V VMs are backed up agentless with changed-block tracking and can be restored as new VMs or in place. Proxmox and VMware VMs can also start directly from the backup (instant recovery).
Does it work with the free VMware ESXi license?
Yes. On hosts with the free license the API is read-only, so BackupZit takes snapshots and restores over SSH; licensed hosts and vCenter use the vSphere API.
Can I restore a whole server onto new hardware?
Yes. Boot the Windows or Linux recovery ISO, pick the backup in the console and restore the disks — drivers for different hardware are handled. A Linux system can also be restored as a new Proxmox VM (P2V).
Where are the backups stored?
On storage you choose: SFTP servers and NAS, S3-compatible storage (AWS, Wasabi, Backblaze B2, MinIO, Google Cloud Storage), SMB shares, Azure Blob Storage, rotating USB disks, local disks or the BackupZit hardened repository. Backups are deduplicated, compressed and encrypted with AES-256.
Does BackupZit protect against ransomware?
Backups can be immutable (S3 Object Lock or the write-once hardened repository). Backups that look like ransomware or mass deletion are detected and the job's retention pauses automatically, so the last clean backups stay. Automatic restore tests check that backups can really be restored.
Does BackupZit need the cloud or an internet connection?
No. Every organization runs its own console in its own network; there is no cloud service and nothing has to be exposed to the internet. Updates can also be uploaded by hand on offline consoles.
Is BackupZit an alternative to Veeam or NAKIVO?
BackupZit covers the same core jobs — agent and agentless VM backup, bare-metal recovery, immutable storage, Microsoft 365 — as a self-hosted, open-source product without per-machine licenses.
