Folders names with Square Brackets are excluded - /source/test[1]

I have been playing around with script and noticed that not all files get backed up. I'm not coming from a IT-background, so my apologies in advance if I am missing the obvious.

Some folder names that do get backed up are

e:\source\# Michael data
e:\source\% My Courses

However these will not backup:

e:\source\more test [abc]

I think this discussion might be relevant:

Thank you for your report.

Does the script's log report any kind of exception ?

 Scanning ...
Get-ChildItem : The specified wildcard pattern is not valid: [test1 test2

 There are no files matching the selection criteria. Possible reasons:
 - All source directories are empty
 - No file match selection criteria
 - User Cancel Request
Dear Anlan,
This exception sometimes shows up, sometimes it does not. I'll try to narrow it down more.

digging some resources I've found the problem which is better described here :
Making long things short: square brackets are interpreted by the cmdlet as range operator.

I will briefly modify the script to make use of -LiteralPath switch.

Thank you for inspiring me.

All Done !! :) -- It all works beautifully now.

The 7zbackup script cannot be praised enough. It's really f@#king great!
The rotate feature is damn impressive, and must have been hard to code!

Not really ... probably the easiest feature.
Nevertheless I am glad you find the script so useful.

I only wish someone had the opportunity to donate a few dollars to sustain the development. But, at the moment, noone did it.

Hi Anlan,

I have managed to get 7zbackup added to the website
Hope this will increase its exposure to the world a bit.

Do you think 7zbackup could be ported to the Mac easily?
I have switched to the Mac and miss it all ready!

Hi Michael,
thank you so much for helping 7zbackup to gain popularity.

About your question on Mac ... well ... basically 7zbackup.ps1 is a shell script: therefore I assume that someone with enough knowledge of shell scripting for *nix systems (bash, perl, php ... ) could try to translate it to work on Macs (unfortunately not me). Must also underline that, AFAIK, there is no Official 7zip binary for Mac.
