Script to create archive using powershell and 7zip

Question

We have several servers that write log files to C:\\Logs on a daily basis. Every month, a script is supposed to run to identify files older than 30 days, archive them, and delet

Answer 1

    $Hname = hostname #Name of server
    $Source = "C:\logs" #Folder where log files reside
    $Archive = "C:\logs\$hname\Archive.zip" #Folder where archive file will be created
    $Extension = "*.txt" #Only files with this extension will be identified and archived

    $Days = "30" #Number of days past today's date that will be archived
    $CutDay = [DateTime]::Now.AddDays($Days)
    $Files  =  get-childitem $Source  -include $Extension -recurse | Where-Object {$_.LastWriteTime -lt $CutDay}                                                         

    foreach ($File in $Files)
    {
        write-host "File Name : $File " $File.LastWriteTime 
    }

    pushd $Source
    $FileNames = @($Files | %{$_.FullName.Substring($Source.Length+1)} )

    if($FileNames.Count -ne 0)
    {
        [string]$Zip = "C:\apps\7-zip\7z.exe"; #path to 7Zip executable
        [array]$arguments = @("a", "-tzip", "-y", $Archive) + $FileNames
        & $Zip $arguments ;
    }

    foreach ($File in $Files)
    {
        write-host "Deleting file :"$File
        #remove-item $File -exclude *.zip
    }
    else
    {
        write-host "No files to archive"
    }

    write-host "Archive Completed"
