What methods do you have in place for a complete backup and disaster recovery of an OTRS system? What is the preferred method to backing up the system both in circumstances with and without a tape drive in the machine itself?
We do an incremental rsync of /opt/otrs and Apache directories on a off-site box, so that we can also keep old copies. Disaster recovery includes not only backing up data but also being able to quickly reinstall applications without having to work on their compilation, configuration, permission settings etc. Furthermore, the meaning of disaster recovery in your specific environment depends on hardware configuration (RAID?), needed timing (30 min? 60 min? 2 hours?). For example in a mission-critical setup you would have a read-only disk image of the OS + Apache + /opt/otrs and then a disk for storage: this way you don't have to worry about your startup disk and only get images of the storage disk. In a cluster setup you may have a NFS export with application and data or even PXE boot. As always, It Depends(tm) ;) - Alessandro Ranellucci
