Duplicati vs VM Backup

Duplicati is backup software for Windows, macOS and Linux, covering computers and servers. It can back up desktops, laptops, local servers, NAS devices, Microsoft 365, Google Workspace and S3 buckets. Destinations include S3, WebDAV, SFTP and local hardware; cloud data can also be copied to an on-prem SAN or private S3 cluster. Data is encrypted locally with AES-256 before transfer, and only changed blocks are sent. Retention settings can remove older backups or keep a chosen number. Administrators can distribute backup configurations to clients, delegate local management to regional IT staff and isolate clients in sub-organizations. One subscription supports unlimited clients and endpoints. The free plan provides an insights dashboard, monitoring for up to two machines and access to the last 200 backups. Pro adds alerts, AI analysis, remote management, retention, storage and priority support. Enterprise adds organization management, configuration assistance, SSO with MFA, agent deployment and credential management. Pro is $2/mo billed annually; Enterprise is $3/mo billed yearly and requires at least 10 machines.

VM Backup is Hornetsecurity’s backup and replication software for virtual machines running on Hyper-V, VMware, and Proxmox. It runs on Windows hosts and can schedule live backups as often as every five minutes without downtime. Recovery options include restoring a whole VM or selected files and Exchange items, moving a restore to another host, and starting a VM from backup. It supports management of the three hypervisors from one console, with a separate console for remote installations. Listed destinations include Microsoft Azure, Impossible Cloud Storage, Backblaze B2, Amazon S3, and Wasabi; the product also lists AES-256 encryption and a monitor that checks backup storage integrity and may attempt repairs in a later job. VMware backups can be restored to Hyper-V and vice versa. Proxmox LXC container backups are unsupported, and the listed requirements say Proxmox replication and CDP were not yet available in that version information. Free Edition covers two VMs per host; a fully featured trial lasts 30 days.
