Is there any difference? For me there are two Disaster Recovery categories, Backup and Replication. HA falls in the second category. > In any HA solution you would assure that your services are running the highest > uptime possible and this kind of solution in most cases is implemented with > clusters.

Replication purpose is provide the better possible RTO. For obvious reasons, Bacula cannot re-distribute a failed backup job yet (perhaps never will), but I don't think it is necessarelly a problem for Replication. > HA implementation in Bacula is extremely straightforward when using a shared > storage clustering solution. >> Both director can access the Secondary SD. >> An Admin Job with a Shell Script daily bscans all volumes in to the Secondary >> Director and its catalog. >> All bscanned volumes comes with the Archived status, so they are basically >> Read-Only. >> Advantage: you can restore jobs from both environments, any time. => [ >> http://bacula.us/bacula-server-and-backups-replication-for-high-availability/ >> | >> http://bacula.us/bacula-server-and-backups-replication-for-high-availability/ >> ] >> Perhaps, a "bscan all" bconsole command would be a nice feature to sync all >> disk >> based volumes to catalog and improve the proccess a little bit more. > This is a Disaster Recovery solution.

A surprising large amount of my customers wants Bacula HA but do not want to use clusters or 3rd party solutions. Don't know the reason for that phenomenom.
