How Would I write this Regular Expression?

Question

How would I write a Regular Expression for this?

Backup 1 of (anything here, maybe multiple words).html

I thought it would be this

Backup\s1\sof(.*)\.html

but it's not working. I'm using power grep... am I supposed to put something at the beginning and end? Thanks!

^Backup\s\d+\sof\s\([^\(\)]+\)\.html$

• ^ assert start of string
  • Backup matches characters "Backup"
  • \s matches any whitespace character
  • \d+ matches one or more numbers
  • \s matches any whitespace character
  • of matches characters "of"
  • \s matches any whitespace character
  • \( matches character '('
  • [^\(\)]+ matches one or more characters not including '(' or ')' characters
  • \) matches character ')'
  • \. matches character '.'
  • html matches characters "html"
• $ assert end of string
