Datensicherung und Disaster Recovery können Ihrem Unternehmen helfen, sich auf das Schlimmste vorzubereiten.

Wesentliche Punkte:

  • Data backup is standard operating procedure for business continuity.
  • But you also need solid disaster recovery capabilities.
  • Modern realities from remote work to ransomware are driving home this dual mandate.

We all hear the constant reminder to “back up your data.” And if your organization is concerned about business continuity, keeping a copy of all your records somewhere safe can help. But it doesn’t insure against business disruption. Without disaster recovery capabilities, data backup has limited use.

What Is Backup and Disaster Recovery?  

Data backup is not the same as disaster recovery.

  • Data backup makes a copy of your emails, files and other data and stores it for safekeeping — whether in the cloud, in hardware on your company’s premises, or in some hybrid of the two.
  • Disaster recovery is your ability to pull that data up — clean and ready to go — and restore it without corruption so you can get back to work.

Datensicherung und Disaster Recovery können unabhängig voneinander sein und sich dennoch ergänzen. Eine Sicherungskopie kann ausreichend sein, um kleinere Fälle von versehentlichem Löschen von Daten durch Benutzer oder Datenbeschädigung durch Apps zu bewältigen. Für katastrophalere Vorfälle wie Cyberangriffe, Naturkatastrophen und größere technische Ausfälle, die eine vollständige Duplizierung von Daten oder sogar den Wechsel in ein anderes Rechenzentrum erfordern könnten, benötigen Sie jedoch einen Disaster-Recovery-Plan. Die aktuelle Welle von Ransomware-Angriffen macht Disaster Recovery wichtiger denn je.

“Disaster recovery is at a very severe end of the spectrum and something you hope you never have to utilize. It's like the axe behind the glass panel,” said Garth Landers, Mimecast’s director of product marketing. “Backup is like a fire alarm. It could be used more frequently. Data loss is a part of everyday life.”

Disaster recovery planning involves steps including:[i]

  • Inventory of your company’s hardware, software, cloud services and data
  • Identification of disaster recovery priorities
  • Setup of backup and recovery facilities and tools
  • Establishment of disaster recovery triggers and procedures
  • Delegation of roles in the event of a disaster
  • Documentation of communications protocols
  • Testing and periodic updating of the plan

The Cost/Benefit of Backup and Disaster Recovery

Wenn sie gut zusammenarbeiten, können Datensicherung und Disaster Recovery die Geschäftskontinuität sicherstellen. Der Bedarf Ihres Unternehmens hängt hauptsächlich von seiner Größe, der Branche, in der es tätig ist, Ihrem Budget und davon ab, wie viele Ihrer Daten geschäftskritisch sind. Zu den externen Einflüssen kann alles gehören, von extremen Wetterbedingungen bis hin zu Vorschriften.

In der heutigen hyperkompetitiven Geschäftsumgebung mit Just-in-Time-Produktion und Echtzeitbetrieb sind die Kosten für Ausfallzeiten ein wichtiger Faktor. Unternehmen wollen so lange wie möglich online bleiben. Gleichzeitig halten sie sich bei den Ausgaben zurück. Nicht alle Unternehmen haben das Budget, um sich eine umfangreiche Datensicherung und Disaster Recovery zu leisten.

One rule of thumb is that the faster the recovery, the more it costs. That requires prioritizing the most important data and deciding how often it must be backed up. Managers must agree on how much data they can afford to lose in the case of a disruption because data will only be restored to the point of the last backup. That necessarily includes agreement on which data is mission-critical.

Financial organizations have some of the most demanding requirements for backup and disaster recovery. Others, like healthcare companies, may be able to prioritize patient-critical operations over more mundane tasks, said Shane Harris, senior director of product management at Mimecast.

Cloud Backup Considerations

Increasingly, companies need to factor in how much their cloud-based service providers, for such essentials as email, offer built-in backup and recovery functions.

Some cloud services’ backup could be limited to as little as 60 to 90 days, for example, which may or may not be long enough for your company’s needs. If regulations require saving data for years rather than months, you might need to purchase supplemental backup for compliance.

Another reason for a longer backup is cybersecurity. Not all data breaches are exposed right away. For example, a highly publicized cyberattack that recently affected thousands of U.S. organizations actually began a year before the news got out, as an advanced persistent threat embedded in their networks. Effective security requires long-term data backups be available to ensure that safe, clean data can be restored and business continuity maintained when a breach is detected.

“Ransomware is a great example of that. Not all ransomware exposes itself within 90 days,” noted Harris. “So, is that protection enough to really protect you from something like ransomware? No.”

Backup and Disaster Recovery After COVID

The disruption caused by the COVID-19 pandemic is also expected to have long-term effects on the need for data backup and recovery. As more companies have adapted to remote work, the use of cloud-based apps has expanded. Data is now more fragmented than ever in many organizations.

“That creates a challenge in terms of centralization of control, management, administration, access to that data, insurance, backup and disaster recovery,” said Landers. Organizations need data backup and recovery to take a platform approach — including central management of continuity events on a web-based console — and solve for a variety of data protection and governance requirements, he said.

The business need is evident in a Gartner survey showing that only 12% of organizations said they were able to keep operating as normal during the COVID pandemic. Not surprisingly, about half of the organizations polled by Gartner also say they will increase their budgets for cloud-based disaster recovery in the next two years.[ii] Most organizations will need to settle into this “new normal” for the long haul: Gartner also found 90% of human resources leaders said they would let employees work remotely even after the COVID vaccine is adopted widely.[iii]

Was lässt sich daraus schließen?

Datensicherung und Disaster Recovery können die Ausfallzeiten Ihres Unternehmens bei Cyberangriffen, Naturkatastrophen und größeren technischen Ausfällen minimieren. Zusammen tragen sie dazu bei, die Geschäftskontinuität inmitten von Herausforderungen zu gewährleisten, die von Remote-Arbeit bis hin zu Ransomware reichen.
