Using HBS as part of SSD secure delete process

[JayDee]

I'm thinking of a strategy to securely delete personal data files from an SSD based computer.

Since the data and OS and installed programs are all on the same SSD,
just doing a SSD reset is not suitable. I am aware of the limitations of SSD
as far as secure delete of files is concerned so trying to securely delete
individual files or folders will not work.

I am considering the following steps.

1. Do a "regular delete" of data files including Recycle bin
    and other places where data may be stored.
      (at this point most of these files are recoverable)
2. Use Hasleo to do a System backup
3. Do an SSD reset to completely clear all data
      ( use something such as manufacturer app or PartedMagic)
4. Restore the system from Hasleo

I'm making an assumption here that Hasleo system backup only copies
active storage to the backup not any of the "deleted" data.  

Comments would be welcome.
