An introduction to disaster recovery And how DrAAS from I.R.I.S. Ondit can help!
Events That Impact Information Availability Events that require a data center move: Fewer than 1% of occurrences Natural disasters Business mergers, acquisitions, or relocations Unscheduled events/failures: 15% Server, application, network, or storage failures Processing or operator errors Scheduled events/competing workloads: 85% Maintenance, migrations, backups/restores, batch jobs, new applications or upgrades Data warehouse extracts, builds, and loads Page 2

Some terminology explained Page 4
Some terminology DRP: disaster recovery plan (or procedure) HA: high availability BCP: business con8nouity plan RTO: recovery 8me objec8ve RPO: recovery point objec8ve Failover: moving your load to a secondary loca8on Failback: moving your load to the original loca8on FT: fault tolerant Page 5
DR <> HA! High Availability: A technology design that minimizes IT disrup8ons by providing IT con8nuity through redundant or fault- tolerant components. Typically no or minimal impact on the services Disaster Recovery: A pre- planned approach for reestablishing IT func8ons and their suppor8ng components at an alternate facility when normal repair ac8vi8es cannot recover them in a reasonable 8meframe. Typically (very) high disrup8on on the services Page 6
RTO & RPO, a critical desicion Page 7
Protecting Information Is a Business Decision Recovery point objective (RPO): How recent is the point in time for your recovery? Recovery time objective (RTO): How fast can you restart a failed application? (RPO+RTO = Acceptable Business Risk) RPO RTO DAYS HRS MIN SEC EVENT SEC MIN HRS TIME DAYS Page 8

Disaster strikes, what do you need? Page 11
What do I need to perform a DRP? A plan! Data A copy, replica or backup of your cri8cal data, files, databases, systems, mails,.. Resources Compute resources to run your applica8ons, databases, fileservers, mails, websites, Connec8on A connec8on towards your DR site/provider Page 12
How to protect your (backup) data? Main driver is your required RTO/RPO Price considera8ons Technical considera8ons From tape(vaul8ng) to con8nious data protec8on/ replica8on Page 13

Traditional backup? Where to store your data? Onsite (Local) Benefits ü Cheap ü Backup Everything Drawbacks ü Does not protect against site failure ü Very hard to monitor Offsite (tape vaul8ng) Benefits ü Cheap ü Backup Everything ü Protects against site failure Drawbacks ü Unreliable ü High legal risk ü Requires training ü Difficult to monitor Cloud Benefits ü Protects against site failure ü Low anxiety (reliable) ü Zero interven3on required ü Restore to anywhere ü Easy to monitor Drawbacks ü (More) expensive ü Requires a performant connec8on Page 16
Data requires resources to run! RTO is also an important driver here! Technical and budget drivers Possibili8es include: Rolling in rented hardware Cold standby hardware Hot standby hardware Flexible cloud resources (IAAS) Page 17
Without a connection you re nowhere. Your employees, users and customers must be able to connect to the DR site Public IP What about your public IP addresses. Required bandwidth Private networks Extension of your MPLS/VPLS/ private network VPN tunnels Page 18

Our BuAAS and DrAAS solutions Back Up to and Restore from the Cloud Online Servers, backup Storage, Network/ Applica8ons and data remain on- premises, with Infrastructure data being backed up into the cloud and restored onto on- premises hardware when a disaster occurs. In other words, the backup in the cloud becomes a subs6tute Database/Processes/ for tape- based off- site backups. Platform Back Up to and Restore to the Cloud Cloud Application/Software based DR Data is not restored back to on- premises infrastructure; instead it is restored to virtual machines in the cloud. This requires both cloud storage and cloud compute resources. The restore can be done when a disaster is declared or on a con8nuous basis (pre- staged). Pre- staging DR VMs and keeping them rela6vely up- to- date through scheduled restores is crucial. Page 35
Our BuAAS and DrAAS solutions (2) Replica3on of Virtual Machines in the Cloud Cloud to Cloud Servers, Storage, Network/ For firms that require aggressive recovery 8me (RTO) and recovery point Infrastructure objec8ves (RPOs), as well as applica8on awareness, replica8on is the data movement op8on of choice. Replica8on to cloud virtual machines can be used to protect both cloud and on- premises produc8on instances. Database/Processes/ Platform In other words, replica6on is suitable for both cloud- VM- to- cloud- VM and on- premises- to- cloud- VM data protec6on Application/Software The benefits provide important features for disaster recovery: VM startup can be easily automated, lowering recovery 8mes Virtualisa8on eliminates hardware dependencies, poten8ally lowering hardware requirements at the backup site. Applica8on agnos8c state replica8on solware can be run outside of the VM, trea8ng it as a black box. Page 36
