Disaster Recovery Linux Manager
What it is
Disaster Recovery Linux Manager (DRLM) is an on-premises tool for centrally managing GNU/Linux disaster recovery with Relax-and-Recover (ReaR). It is intended for small-to-large implementations covering physical and virtual Linux systems. DRLM manages ReaR installations, can schedule them, and can start backups remotely. Recovery includes network boot, and documented backup methods include ReaR PXE and NETFS (NFS). The project also documents incremental backups, encrypted backup files, and TLS-secured rsync backups. DRLM can install clients automatically from the server when they are reachable over SSH. The latest production release is available as source archives in tgz and zip formats, and the project is released under the GNU General Public License version 3. Listed server operating systems include Debian, Ubuntu, CentOS, Rocky Linux, RHEL, openSUSE Leap, and SLES versions. The API uses HTTPS on port 443. DRLM is free, while professional support is a paid service; contributor support is available when contributors have time. The installation guide recommends a minimal Linux distribution dedicated to the DRLM server.
For and against
For
- Manages ReaR installations and scheduled backups
- Supports network boot and recovery
- Documents incremental, encrypted, and TLS-secured backups
- Works with physical and virtual GNU/Linux systems
Against
- Requires a dedicated minimal Linux server installation
- Automatic client installation requires SSH reachability
- Professional support is a paid service
The verdict
DRLM offers centralized ReaR management and documented backup and recovery options for Linux environments. Its dedicated-server assumption and SSH requirement for automatic client installation are important deployment considerations.
Who it suits
DRLM may suit organizations managing recovery for GNU/Linux systems, from small to large deployments. It is intended for teams able to dedicate a minimal Linux installation to the server and make clients reachable over SSH for automatic installation.
