How does steady knowledge safety work?
It’s possible you’ll be questioning how steady knowledge safety works. Let’s first take a look at its background.
When the strategy was first launched, it was used to keep away from the frequent downside of shrinking backup home windows. Earlier than steady knowledge safety was invented, many corporations would run a nightly tape backup – however there was an issue.
These corporations discovered that they needed to shield a repeatedly rising knowledge set inside a particular backup window, and though there are numerous methods to hurry up tape backups, there was nonetheless a restrict to how a lot knowledge you may backup inside a set time frame.

As a result of steady knowledge safety runs within the background, it could possibly acknowledge any adjustments made to your knowledge. As soon as the software program discovers these adjustments, they may instantly be backed as much as the grasp backup file.
Supply: Datacore
CDP retains monitor of each single change till the final write earlier than failure which can mean you can restore your pc to that time of any earlier level previous to the information loss or corruption.
