IIS Log File Archive

archiveLogs.ps1

##################################################################
#   IIS Web Log Archive Script
#     Takes a path to a directory containing IIS Log files
#     Zips them up with 7-zip and stores the zip in a
#     directory multiple levels up.
#     Original log files are then deleted
#    
#   Expected folder structures:
#     X:\Some\Directory\ContainAllLogs\
#     |-  Live
#      |-  Domain Name [server.com]
#        |-  Subdomain [www]  ** This is the path that IIS is configured with
#          |-  IIS Auto Created folder [w3svcxxxxxx]  
#    |-  Archive
#      |-  Domain Name [server.com]
#        |-  Subdomain [www]  ** This is where the zip will go
#
#   Usage:
#       Within a .bat file:
#       
#       powershell set-executionpolicy Unrestricted
#       REM -- *.ashfordapps.com
#       powershell "& .\archiveLogs.ps1 "X:\WebsiteLogs\Live\Domain.com\Subdomain\W3SVC286639526" "
