Disaster Recovery Linux Manager vs NAKIVO Backup & Replication

Disaster Recovery Linux Manager (DRLM) is a free, on-premises system for centrally managing GNU/Linux disaster recovery with Relax-and-Recover (ReaR). It manages ReaR installations, schedules them, starts backups remotely, and supports network boot and recovery. Documented methods include ReaR PXE and NETFS (NFS), along with incremental backups, encrypted backup files, and TLS-secured rsync backups. DRLM can automatically install clients from the server when those clients are reachable over SSH. The project supports physical and virtual GNU/Linux systems and lists Debian, Ubuntu, CentOS, Rocky Linux, RHEL, openSUSE Leap, and SLES versions for the server. Error reporting integrations include HP OpenView, Nagios, Zabbix, and email. Its API uses HTTPS on port 443. Production downloads are source archives in tgz and zip formats, and the project uses the GNU General Public License version 3. The installation guide assumes a minimal Linux installation dedicated to the DRLM server.

NAKIVO Backup & Replication provides backup, replication, failover, backup copies, granular restore, and disaster recovery orchestration for virtual, physical, cloud, and SaaS environments. It supports image-based, application-aware, incremental backups and replication, with retention of up to 1,000 recovery points using GFS rotation. Supported workloads include VMware, Hyper-V, Nutanix AHV, Proxmox VE, Amazon EC2, Microsoft 365, Oracle Database, Windows and Linux machines, and NFS/SMB file shares. Site Recovery workflows can automate disaster recovery actions across VMware, Hyper-V, Nutanix AHV, and Amazon EC2. Deployment is available as a virtual appliance or by installing it on a supported machine or NAS device. NAKIVO says physical machine backups use AES 256-bit encryption. Linux repositories can be password-encrypted, and repository self-healing can check data integrity and repair errors where possible. Active Directory integration and an HTTP API support monitoring, automation, and orchestration integrations. It runs on web, Windows, Linux, self-hosted environments, and via API. Subscription starts at $2.50 a month per workload; Perpetual starts at $229, paid once per CPU socket. A 15-day trial enables all features, but there is no free plan.
