I need a script to run every day and zip the folder that was created the previous day.
I then need the zipped version to be moved to a network location.
I was thinking of using 7zip to do the zipping as this is installed on the servers but I'm open to alternatives if there is a better way\method\tool.

Any help will be greatly appreciated.

Here are some additional details.

The folders to zip are named in this format:

I need to move the zipped version from

Thanks In advance for any help

As this is not a free script shop here you would have to write a script by yourself. But if I'm not wrong you don't even need a sophisticated complex script for that. A proper command line for 7zip should be enough. Addditional information you can find here: 7Zip Command Line Syntax.
If you have a question to a Powershell script you wrote you can post here the relevant part of the script we will try to help you as good as we're able to. 😉

HI OLaf,
I don't think just the command line for 7zip is enough.

To zip the folder using 7zip command line is just

7za a -tzip 20171227.7zip 20171227

This is not my issue.
I don't know how to target the folder dated from the previous days date.

Okay so I've managed to coble this script together however it's failing at my $yesterdaysfolder variable

$pathTo7zip = "C:\Users\gustasoh\Desktop\7z1701-extra\x64\7za.exe"
$sourcefolder = "C:\Users\gustasoh\Desktop\7z1701-extra\x64"
$yesterdaysfolder = "(Get-Date).AddDays(-1).ToString('yyyyMMdd')"
$Destination1 = "C:\Users\gustasoh\Desktop\ZIPPED\"

C:\Users\gustasoh\Desktop\7z1701-extra\x64\7za.exe a -tzip *.7zip $sourcefolder\$yesterdaysfolder

#Check destination path
if (Test-Path $Destination1)
  #then copy
  Copy-Item $Source *.7zip $Destination1

$yesterdaysfolder should be like this:

$yesterdaysfolder = "$((Get-Date).AddDays(-1).ToString('yyyyMMdd'))"

As for a "better way/method/tool" to 7zip, your requirements don't really scream out "I need to use 7zip". Can you try using the Compress-Archive cmdlet?
Something like this should do the job:

$sourceFolder = "Insert\Source\Folder\path\here"
$Date = "$((Get-Date).AddDays(-1).ToString('yyyyMMdd'))"
$archivePath = "D:\usr\sap\gkretail\ucon\dataexchange\export_channel\results\export\EXPORT_SUCCESS"
$archivePath2 = "\\SOL000483\\GK_Transaction_Archive"

Get-ChildItem "$sourcefolder\$Date" -Recurse | Compress-Archive -DestinationPath "$archivePath\$"

if (Test-Path "$archivePath\$")
  Copy-Item -Path "$archivePath\$" -Destination "$archivePath2\$" 

Just fill out the $sourceFolder variable: the path to the $Date folders.

And looking at this after my first sip of coffee, I realized that your Get-Date was already converting it to a string, so the quotes weren't needed.

$yesterdaysfolder = (Get-Date).AddDays(-1).ToString('yyyyMMdd')
$Date = (Get-Date).AddDays(-1).ToString('yyyyMMdd')

Hi Jeremy,
Thanks for the help.
I have tried the mods you suggested and I get this error.

Compress-Archive : The term 'Compress-Archive' is not recognized as the name of a cmdlet,

You need a minimum version of PowerShell 3, so you are probably running 2 or lower. So back to using 7zip. Just adjust your $yesterdaysfolder to the format that I specified above.

This is what I'm using

If I'm not wrong Compress-Archive has been released with version 5. So either you update to a current version or you use your 7zip command line instead.

No matter what version of PoSh you are using. You can compress with PoSH and .Net.
So taken your block and tweaking it a bit – Try this approach, nothing extra needed

Setup source and destination and criteria


    $Source = 'D:\Temp'
    $Destination = 'D:\Temp\ArchiveDestination'
    $ArchiveDate = (Get-Date).AddDays(-1)

    "`nShowing archive source folders"
    Get-ChildItem -Path $Source -Directory -Recurse | Select Name,LastWriteTime | Select -First 9

    "`nCount of current archives to date of the source folders: " + (Get-ChildItem -Path $Destination -Filter '*.zip').Count + "`n"

Instantiate compression class
Validate ArchiveDate, compress and archive if true, else take no actions

    Add-Type -AssemblyName 'System.IO.Compression.FileSystem'

    ForEach ($SourceFolder in (Get-ChildItem -Path $Source -Directory))
    If ($SourceFolder.LastWriteTime -lt $ArchiveDate)
    "The folder named – $($SourceFolder.Name) – matches archive date. Archiving Now."
    [IO.Compression.Zipfile]::CreateFromDirectory($SourceFolder.FullName, "$Destination\$($SourceFolder.Name).zip")
    Else {Write-Warning -Message "$($SourceFolder.Name) checked does not met archive date. No actions taken."}

    "`nCount of current and new archives: " +
    (Get-ChildItem -Path $Destination -Filter '*.zip').Count


    Showing archive source folders

Thanks a lot for helping with this.
It works very well.

There is one snag.
I only need it to zip yesterdays data. this seems to all the data in the source again.
What part of the code can I change to only zip yesterdays daya.

I intend to set this as a scheduled task to run early morning to archive sales data from only the previous day.

Sorry if that sounds rude for you but don't you think you could put a little effort by yourself? And Jeremy even answered this already. The code you get here does not have a copyright – you're welcome to change it to your needs. Feel free to play a little with it and learn something while you do so – that's how we all do it. And of course you can always ask your prefered internet search engine to help you out.

January 5, 2018 at 12:18 pm

No that's not rude Olaf.
I understand but I'm just not that good when it comes to scripting.

I'll have a further play and see where I get.

Thanks for all the help all you guys have given me here.

Hi all,
I have managed to put together a working script now and wanted to thank all of you guys for your time and assistance.
I the spirit of sharing I thought I would post it here in case it helps somebody else.

Add-Type -AssemblyName 'System.IO.Compression.FileSystem'

$Source = 'C:\7z1701-extra\x64'
$Destination = 'C:\7z1701-extra\x64\ZIPPED'

$d = (get-date).adddays(-1).tostring('yyyyMMdd')
$SourceFolder = Join-Path -Path $Source -ChildPath $d

Write-Verbose "Archiving $SourceFolder"
[IO.Compression.Zipfile]::CreateFromDirectory($SourceFolder, "$Destination\$")

Move-Item -Path $Destination\*.zip -Destination \\\GK_Transaction_Archive

Thanks everyone
