Disaster Recovery Linux Manager
What Disaster Recovery Linux Manager is
Disaster Recovery Linux Manager (DRLM) centrally manages GNU/Linux disaster recovery using Relax-and-Recover (ReaR). It is intended for small-to-large implementations and supports physical and virtual GNU/Linux systems. DRLM manages ReaR installations, can schedule them, and can start backups remotely. Its documented methods include ReaR PXE and NETFS (NFS), with network boot and recovery. 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. Listed server operating systems include Debian, Ubuntu, CentOS, Rocky Linux, RHEL, openSUSE Leap, and SLES versions. Error reporting integrations include HP OpenView, Nagios, Zabbix, and email; its API uses HTTPS on port 443. The latest production release is offered as tgz and zip source archives. DRLM is free, on-premises software released under the GNU General Public License version 3. Its installation guide assumes a minimal Linux distribution installation dedicated to the server. Free contributor support is available when contributors have time, while professional support is paid.
Who it suits
DRLM suits organizations managing disaster recovery for GNU/Linux physical or virtual systems with ReaR. It is intended for small-to-large implementations, provided they can dedicate a minimal Linux installation to the server.
What it does well
- Free and on-premises.
- Schedules ReaR installations and remote backups.
- Supports network boot and recovery.
- Documents incremental and encrypted backups.
- Offers error reporting integrations and an API.
What to know first
- Server needs a dedicated minimal Linux installation.
- Automatic client installation requires SSH reachability.
- Free support depends on contributor availability.
- Professional support is paid.
Limits
The installation guide assumes a minimal Linux distribution installation dedicated to the DRLM server. Free support is provided by contributors when available; professional support is paid.
Getting started
- Open https://drlm.org/.
- Download the latest production release as a tgz or zip source archive.
- Prepare a minimal Linux installation dedicated to the DRLM server.
