There’s an old saying from IT administrators: no backup, no sympathy. Today we release the new version 21 of the O&O DiskImage Professional and Server Editions!
We’re proud to introduce the latest versions of our Professional and Server Editions, developed exclusively for business and advanced users – and designed to handle today’s increasing demands for speed, control, and reliability. The Premium Edition, already released earlier this year, remains the ideal solution for home users who want ease of use and peace of mind. But for businesses, the new Professional and Server Editions bring the full power of our technology into the hands of IT professionals and advanced users.
The most important security software on your machines
A backup is the most important protection against data loss. With the new O&O DiskImage, a data backup of the entire machine, hard disks and partitions can be created even faster and more conveniently. Individual files and directories can also be easily backed up.
This boot medium can also be used to create a 1:1 copy of a machine when it is switched off, without it being modified or O&O DiskImage having to be installed on it. The latest version of O&O DiskImage expands the existing range of functions again and also offers numerous improvements.
Cyber Security and Data Backup: A must in the digital era
The recently published report by the German Federal Office for Information Security (BSI) on the state of IT security shows that ransomware attacks in Germany cause billions of euros in damage every year – a problem that affects companies and private individuals alike and cannot be completely prevented even by the most modern anti-malware solutions. O&O DiskImage offers a powerful, user-friendly and reliable solution to back up valuable data and thus prevent possible loss due to cyber-attacks, hardware failures or other incidents.
According to the current BSI report, ransomware attacks have increased significantly again in the past year. Small and medium-sized companies have increasingly become the target of such attacks, in which attackers encrypt data and demand a ransom. This often results in high recovery costs or data loss that cannot be recovered. However, the key to limiting damage lies in prevention: regular backups of business-critical data.
Comprehensive functionality for virtual machines
O&O DiskImage now offers a huge range of functions for working with virtual machines. You can now create incremental and differential images of virtual disks, merge them together and mount them as drives.
