A backup of a file in a restore point may not be available after a hard drive crash because restore points are typically stored on the same physical drive as the original files. If the hard drive fails, the data, including the restore points, is often irretrievable. Additionally, restore points are designed for system recovery rather than individual file recovery, meaning they may not retain all versions or backups of every file. In such cases, relying on separate external backups is crucial for data protection.
If you have enough hard drive space you should always create a restore point.

Restore point
Restoring files on a hard drive can always be done as long as the hard drive itself isn't irrepairably damaged physically. If you are able to replace that hard drive with the hard drive in another computer and boot it up, you should be able to roll back the hard drive to a different restore point where everything was accessable.
Data recovery software enable a person to access and store data at any time. When you do this and your computer crashes it allows you to keep all your data up to the last restore point.
There is a thing called system restore which resets everything on you computer back to factory settings. Or you wipe your hard drive and reinstall your OS (operating system). Better option is to do system restore point which brings your system pretty much back in time to a point where you have not made those changes, but you have to create restore point at that time.

If you are using a standard Windows operating system, you would use the "System Restore" function found in the start menu under Accesories>System Tools if you are in windows 7. for Mac, you will have a System Restore CD, follow it's instructions. For a Linux Operating System, it will most likely not have any such function, requiring you to fix the problem yourself.
If you goto the restore point section and create a restore point yourself, it should explained if and how long it is saved. You are probably better to use the "backup" tools
