DRLM - Disaster Recovery Linux Manager

======================================



Disaster Recovery Linux Manager (DRLM) is a Central Management Open Source

Software for Linux Disaster Recovery and System Migrations, based on

Relax-and-Recover (ReaR).



DRLM provides Central Management and Deployment from small to large

Linux Disaster Recovery Implementations bringing a great Centralized Management

Tool to Linux SysAdmins.



With DRLM SysAdmins can add/delete/modify networks and ReaR clients to manage,

run backups and enable/disable Disaster Recovery system images to recovery

through network.



`Professional services and support are available

`_.



For more detailed information about Disaster Recovery Linux Manager, please

read the Disaster Recovery Linux Manager `Project Web Page

`_.



REQUIREMENTS

------------



As DRLM has been solely written in the bash language we need the

bash shell which is standard available on all GNU/Linux based systems.



Also requires some system services in order to work properly:



  * isc-dhcpd

  * nfs-server

  * rsync

  * tftpd

  * qemu-utils

  * sqlite3



All other required programs (like sort, dd, grep, etc.) are so common, that

we don't list them as requirements. In case your specific workflow requires

additional tools, Disaster Recovery Linux Manager will tell you.



DRLM is a tool to manage REAR systems, so all clients need REAR package and

its dependencies to work properly.



For detailed documentation of DRLM and all system and software requirements,

please visit: http://docs.drlm.org



INSTALLATION

------------



On RPM based systems you should use the drlm RPM package. Either obtain it

from the DRLM homepage or build it yourself from the source

tree with:

::



  $ make rpm



This will create an RPM for your distribution. The RPM is not platform-

dependant and should work also on other RPM based distributions.



On DEB based systems you can execute the command:

::



  $ make deb

please read the Disaster Recovery Linux Manager `Documentation Page

CONFIGURATION

-------------



To configure Disaster Recovery Linux Manager you have to edit the configuration

files in '/etc/drlm/'. All '*.conf' files there are part of the configuration,

but only 'local.conf' are intended for the user configuration.
