Does Office 365 back up make sense

Today, many organization messaging services are mission-critical, if messaging system is down than productivity will be down and it will direct effect on business revenue. All of the redundancy, security and fault tolerance in the world cannot help when it comes to a damaged, corrupt, or lost database, backing up the critical data in Exchange Servers is a necessary operational task for all organizations.

As part of the disaster recovery planning, it is important that we have understand how to correctly backup the Exchange Servers. What happens when we delete an email? We have 14 or 30 days to recover it from the dumpster and afterwards it’s gone forever.

Now most of the customer moving to Exchange online (Office365) and its again critical how to recover the deleted emails. If you have Office 365 plans E3 or E4, then you can set the dumpster to keep deleted emails forever. However, if the size of the dumpster is limited then the oldest emails will start to be permanently deleted. Also we can configure the “litigation hold” per specific accounts and retain all deleted emails.

But we have to think about when the data override that is done by accidentally or maliciously by the users. If we did not back up our data in advance, there will be good chance that we cannot recover once we notice that the calendar or Contact were overridden some time ago.

Now, we have to be aware of the risks we take by not backing up your Office 365 data. But what can we do? Well, there are couple of manual tools we can use to manually backup our data.

Does backing up Office 365 make sense

Office 365 has completely change the email business, and most of the organization using Office365. The subscription-based cloud productivity suite boasts more than 7 million users can use the familiar Office applications on many devices including desktop PCs, laptops, tablets and smartphones. Office 365 is one of the quickest adopted cloud applications in history, but it lacks a reliable enterprise backup system as of now.

What is Microsoft doing to backup data

Microsoft is doing a lot to ensure files and documents are always accessible and backed up. It even prides itself in its 99.9% service up-time with regular backups. In a blog post on its site, Microsoft outlined some techniques it used to ensure data was backed up. It constantly replicates data between data centers and storing data in completely redundant environments with backup and restoring capabilities, such as DAG etc. If something happens to one of Microsoft’s data centers, we most likely retain every single one of our emails!

Why should you have your own backup

While Microsoft does replicate and backup its Office 365 service, it only protects its own interests by making sure any loss on its end can be recovered from. Its backup does not protect us from user errors such as accidental deletion or an employee maliciously deleting files.

In this case all the organizations need a third-party solution to deal with this very prevalent form of data loss.

What options are out there

There are more and more third-party backup applications for Office 365 coming to market; some more reliable than others. IT industry news publication.
In addition, we can store your Office 365 data in the same container as all our other corporate data, providing peace of mind to any IT manager.

Whether our data is in the cloud like Office 365, or on our corporate network, it’s smart to keep a backup in a separate location. Cloud-to-cloud backup solutions are coming to market and leading the front to protect data in the cloud and in the office.

Thank You!
