Enterprise Linux

As the title says, what are some options for disaster recovery of Linux running on Power architecture?  Way back in the good old days when we ran AIX, I would simply cut periodic mksysb files that would be used for disaster recovery of the rootvg at our DR site.  Is there something similar for Linux (specifically SLES 12 if it matters)?  Maybe a different methodology entirely?  We have a solution that works well for restoring the non-OS data once we get an environment laid down, it's just getting that initial environment that is causing up issues.

You may use ReaR(Relax and Recover) or Cristie.

Hi Craig ,
Relax-and-Recover ("ReaR") is a disaster recovery framework available for Linux running on Power architecture.

How should I back-up a Linux system?.

There's a tool called ReaR (https://relax-and-recover.org/). We've been using it for several years to restore and/or clone SLES and RHEL systems (both x86_64 and ppc64le). It is available for SLES as a part of the distribution (SLES HA Extensions). Takes some time and effort to learn how to use it, but once you've got it under control it works pretty good.

Hey,

What about Bacula or maybe Clonezilla (and related Partclone)?

All open source, all should run on SLES. ;)

Thanks,

If you have a fairly large number of VMS, and the VMs fully virtualized, and all disk resources are on SAN devices, you might want to take a look at VM Recovery Manager.  It assumes you are willing to run an AIX VM at the DR site as a 'controller', and are using disk subsystem replication to 'mirror' your production site to a DR site.  These provide some additional info.

Craig,

you should take a look at Relax And Recover.
https://relax-and-recover.org/
In SLES 15 it is part of the SUSE Linux Enterprise High Availability Extension.
If you are using SLES for SAP this extension is included.
But you can also use the packages they deliver. They are at newer stable release levels.

Craig, VM Recovery Manager DR handles disaster recovery for Linux VMs using restart technology on top of the storage replication.
Here rootvg is given through SAN. And all the volumes including rootvg volumes will be mirrored to remote storage using storage replication.
In the event of DR, product creates VM at the target site using replicated storage volumes.
It also has DR capabilities to handle SAP HANA single instance, multi-instance recovery.
Product can also handle switching SAP HANA active and passive instances with in a site in case of failures and then perform disaster recovery across sites.
Here VM Recovery Manager dynamically creates VMs at target site during recovery. Since it uses restart technology all NPIV WWPNs and MAC also remains the same at target site.
One of the other interesting feature is that provides DR drill/failover rehearsal feature, without disturbing production VMs/workloads and also ongoing replication between production and DR. 
Since this product works across all guest VMS like Linux, AIX and IBM i, dependencies can also be created among Linux and AIX workloads.
It has GUI and provides single click DR simplified options for 100s of VMs and workloads.
Let me know, if you need more details. We can go through details in the call.

Thanks.
