How do you protect the Microsoft 365 data from ransomware attack in CubeBackup?
As a self-hosted backup solution for Microsoft 365, CubeBackup shares your concerns about potential sophisticated ransomware attacks on your critical data in Microsoft 365. Should an attack occur, your business could suffer many potential losses including business downtime, data breaches of sensitive information, as well as data loss and even a large ransom payout.
Cloud office suites like Microsoft 365 already guard against many kinds of malware by using spam filters against phishing attacks, antivirus scans, and by storing multiple versions of OneDrive data to protect your valuable files. However, the built-in protection and recovery capabilities of Microsoft 365 are still limited in several ways.
It can be an annoying hassle to manually revert all file versions in your OneDrive after an attempted ransomware attack. Additionally, OneDrive only keeps up to 500 versions of files, and will only store older versions for up to 30 days. Deleted files are only recoverable for 93 days, even for administrators. All of this can add up to preventable data loss.
A reliable backup of your business data provides peace of mind by acting as a strong defense against most ransomware attacks. CubeBackup users can rest easy, knowing that they have already added enhanced protection in the event of a ransomware attack.
Detect and protect
CubeBackup encrypts backup data by default before adding it to the backup storage. Since it is stored in a non-executable format, ransomware is prevented from propagating within your backup storage.
CubeBackup will send you periodic email reports on the backup status of your Microsoft 365. A ransomware attack will trigger a large backup of data with many new modified files, which would be shown in your email report, tipping you off to a problem.
By default, CubeBackup will not backup files flagged by Microsoft 365 as abusive. These files will each cause a warning message to appear in the web console and in the email report.
A version history of all files is carefully preserved in CubeBackup according to your customized data retention policy. You can retrieve any previous version of any file simply by clicking the Restore button.
Recover and rebuild
In the unfortunate case of a ransomware attack, CubeBackup can help you quickly recover your valuable data. In fact, it is possible to recover a version of all files in OneDrive as they existed at an earlier point in time (such as before the ransomware attack) with only a few clicks.
Backup data stored in a separate storage location such as a cloud bucket or an external hard drive is even more protected as it introduces another layer of isolation and permissions. As long as the backup storage is available and you have a copy of your CubeBackup encryption key file, you can recover your data by following this disaster recovery plan.
