What it is

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.

Strong points and limits

Strong points

Centralized ReaR management
Schedules and starts backups remotely
Supports PXE and NETFS recovery
Encrypted and incremental backup options
Integrates with monitoring and email

Limits

Requires a dedicated minimal Linux installation
On-premises deployment only
Automatic client installation requires SSH reachability
Professional support is a paid service

Who it suits

DRLM suits administrators managing centralized recovery for small-to-large GNU/Linux environments, including physical and virtual systems. It requires an on-premises server installation.

Verdict

DRLM provides centralized, scriptable disaster-recovery management for GNU/Linux using ReaR. It is free software, but deployment assumes a dedicated minimal Linux server and operational administration.
