It is possible that it will return to Arcabit internet Security because it has the functions of automatic secure backup copies of files that are encrypted and collected on a separate partition.
Or maybe as a scanner of the second opinion, I give secureaplus?
Probably I think that there are many suggestions to recommend backing up the system image. It is not a kind of absolutely necessary, but this is an effective means to save time and make time easier for disk replacement and reformatting with hardware problems.
OneDrive is not a System Image backup solution. OneDrive can only backup files and sync to connected devices.
You can still create a System Repair disc (USB) using the Windows 7 Backup and Restore option. The recovery disc can be used in the case your PC decides to not boot up properly, or something gets corrupted by error or malware.
Also changed thread title to include your username, according to these Guidelines. If you hadn't noticed, no one uses My Config anymore.
You should implement a proper backup. Backing up to OneDrive is ineffective. If you don't want to necessarily do a system backup then a data backup tool like Rollback Rx Home (Free) would work well. Although I also strongly recommend a System Image, Macrium Reflect is also good and free.
