Dell Data Safe Local Backup Question

Dell Data Safe Local Backup Question –

This Dell program allows me to back up my files and folders.  When I do back up, a log is established.  Recently, I deleted from my computer, files for two backup dates (12/12 and 12/9).  However, the log of those deleted backup dates is still listed.

See attachment.

 How can I delete those entries?

I use Vista Home Premium.

Thanks,

Jerry
