Your standard Microsoft365 environment is NOT backed up by Microsoft. Whilst they say it is always available to you, if something goes wrong, there is no backup. Here's 9 reasons you need to be backing up your data...
If somebody deletes a file from OneDrive or deletes an email, they may not be recoverable. An effective backup will enable anything deleted to be restored
If you create a high number of duplicate files as part of your normal collaboration process, you need to manage them. Deleting some of the versions is the simplest way to do that. If you attempt to delete earlier versions or true duplicates, you may accidently remove the wrong files. Again, backups will allow the right files to be restored.
Whether it is an unhappy current employee or someone who's been dismissed and still has access (!!!!), they may sabotage or delete key files, such as customer lists, key templates or other data. This action may go unnoticed for some time, at which point, it may be too late to recover them.
Cybercriminals are becoming more sophisticated and are developing more realistic emails that may trick unsuspecting employees. All it takes is a single click for them to gain access to either exfiltrate data or hold it hostage as part of a ransomware attack. Having a clean backup means you may lose a tiny amount of data, but you are not at the mercy of the cybercriminals. Normal business can be resumed quickly.
When employees leave, IT administrators should back up Microsoft 365 data and reuse the license. Yet this doesn’t always happen, leading to the potential for even more lost data.
Third-party applications may lead to illicit consent grant attacks that can steal valuable data.
Whether you have only company devices (laptops and phones) or you have a more loose BYOD model, allowing staff to use their own devices, lost or stolen devices can lead to data issues.
With AutoSave's default setting being On, overwriting a key document is easier than ever. It's easy to accidentally do this (we've certainly done it!). Backups of business-critical data enable them to be restored quickly and easily.
There are ways to backup your Outlook and other Microsoft365 files, but they are time-consuming and tedious. They are not something you want to be doing multiple times a day to protect your data. You have better things to do!
There are numerous products on the market, but we prefer the Acronis suite of backup solutions. Available for server backups, Microsoft365 and for email, they are fast, safe, easy to use and secure. If you haven't got a backup solution in place and want to talk about how we can help you protect your business-critical data from all of the above, get in touch.
