All your stuff is in your Home folder. The simple solution is to just drag the Home folder to the backup drive. A better solution is to use a backup utility to perform the transfer.

Backup Software

Use any third-party backup utility your prefer. They all create straight file backups meaning you can restore individual files manually if you want by drag and drop copy.

It may be that your disk is failing or is badly corrupted. If the disk is OK then the solution is to erase the disk and install OS X from scratch. But before you do anything I suggest you try backing up your files.

Install El Capitan or Sierra from Scratch

Backup if possible before continuing.

Restart the computer. Immediately after the chime hold down the CommandandRkeys until the Apple logo appears. When the Utility Menu appears:
Select Disk Utility from the Utility Menu and click on Continue button.
When Disk Utility loads select the volume (indented entry, usually Macintosh HD) from the Device list.
Click on the Erase icon in Disk Utility's main window. A panel will drop down.
Set the Format type to Mac OS Extended (Journaled.)
Click on the Apply button, then wait for the Done button to activate and click on it.
Quit Disk Utility and return to the Utility Menu.
Select Reinstall OS X and click on the Continue button.
