CloudBerry Explorer offers PowerShell extension to manage file operations across Amazon Simple Storage Service (Amazon S3) and file system.

Windows PowerShell is a command line shell that helps IT professionals to easily control system and accelerate automation. It includes a number of system administration utilities, improved navigation of common management data such as the registry, certificate store, or WMI, etc.

What is good about PowerShell and CloudBerry Explorer Snap-in?
PowerShell Snap-in allows using the majority of Amazon S3 functionality. You can combine CloudBerry Explorer commands with PowerShell commands. PowerShell is designed to operate with Net objects, so you are not limited with command syntax. You can write complicated scripts with loops and conditions. You can schedule periodical tasks like data backup or cleanup.

This is an example of coping files from local disk to S3 bucket:

Example 1:

The file results.xls will be copied to S3 bucket.

$s3 = Get-CloudS3Connection -Key $key -Secret $secret
$destination = $s3 | Select-CloudFolder -path "myBucket/weeklyreport"
$src = Get-CloudFilesystemConnection | Select-CloudFolder "c:\sales\"
$src | Copy-CloudItem $destination -filter "results.xls"

This can be scheduled for every weekend to copy files into S3 storage (for safety reason for example).

Example 2:

This will copy all files and folders from c:\workdata\ to S3 bucket "myBucket". New directory named by date like 2008_11_01 will be created.

$new_folder_format = Get-Date -uformat "%Y_%m_%d"
$s3 = Get-CloudS3Connection -Key $key -Secret $secret
$destination = $s3 | Select-CloudFolder -path "myBucket" | Add-CloudFolder $new_folder_format
$src = Get-CloudFilesystemConnection | Select-CloudFolder -path "c:\workdata\"
$src | Copy-CloudItem $destination -filter "*"

Commands:

Set-CloudOption -PermissionsInheritance <value> - When you copy or move files to S3 these files can inherit ACL from parent object: bucket or folder.
Values: "donotinherit", "onlyforcloudfront", "inheritall"

Example:
Set-CloudOption -PermissionsInheritance "inheritall"
$s3 = Get-CloudS3Connection <key> <secret>
$destination = $s3 | Select-CloudFolder -path "myBucket/weeklyreport"
$src = Get-CloudFilesystemConnection | Select-CloudFolder "c:\sales\"
$src | Copy-CloudItem $destination -filter "results.xls"

The file "result.xls" will automatically have the same ACL as "myBucket/weeklyreport".

Set-CloudOption -KeepExistingHeaders - Keep existing HTTP headers when replacing files on S3.

Set-CloudOption -DoNotChangePermissionsForExisting <value> - Keep ACL for files when replacing them on S3.
Values: 1 or 0

Set-CloudOption -KeepExistingPemissionsOnCloudCopy <value> - Keep source permissions when copying within S3.
Values: 1 or 0

Copy-CloudSyncFolders - Synchronizes local folders with Amazon S3 bucket. You should specify source folder (local or S3) in pipeline.
-Source <CloudFolder> Amazon S3 bucket or folder or local folder
-Target <CloudFolder> Amazon S3 bucket or folder or local folder

Example:
$s3 = Get-CloudS3Connection <key> <secret>
$source = $s3 | Select-CloudFolder -Path boooks/sync
$local = Get-CloudFileSystemConnection
$target = $local | Select-CloudFolder C:\temp\sync
$source | Copy-CloudSyncFolders $target
Or synchronize content in both ways.
$source | Copy-CloudSyncFolders $target -Bidirectional

New-CloudBucket - Creates a new bucket. You should specify S3 connection in pipeline.
-Connection <CloudS3Connection> S3 connection
-Name <String> Bucket name
-Location <String> Bucket location. US (USA) or EU (europe). By default US location is used.

Example:
$s3 = Get-CloudS3Connection <key> <secret>
$s3 | New-CloudBucket mytestbucket EU

Remove-CloudBucket - Removes bucket. Before bucket will be removed all contents must be removed. It can take long time, progress is displayed.
-Connection <CloudS3Connection> S3 Connection
-Name <String> Bucket name
-Force Suppress warning messages
-Bucket <CloudFolder> Bucket object

Example:
$s3 | Remove-CloudBucket mytestbucket

Get-CloudItemACL - Returns all access control entry for specified item. It can be S3 bucket, folder or file. You can get item using Select-CloudFolder or Get-CloudItems commands.
-Item <CloudItem> Cloud item, it can be bucket, s3 folder or s3 file.
Example:
$fld = $s3 | Select-CloudFolder mytestbucket/documents $fld | Get-CloudItemACL

Add-CloudItemPermission - Grants permission to user or group. If user is not in the ACL, user entry will be added.
-Item <CloudItem> Cloud item, it can be bucket, s3 folder or s3 file.
-UserName <String> Username or group
-Write Grant write permission
-WriteACP Grant write ACP permission
-Read Grant read permission
-ReadACP Grant read ACP permission
-FullControl Grant full control permission. This means that all other permission will be granted.
-CloudACE <CloudACE> Access control entry

Example:
$fld | Add-CloudItemPermission "All Users" -Read

Remove-CloudItemPermission - Revokes permission to user or group. If RemoveUser parameter is specified, user entry will be removed from access control list.
-Item <CloudItem> Cloud item, it can be bucket, s3 folder or s3 file.
-UserName <String> Username or group
-Write Revoke write permission
-WriteACP Revoke write ACP permission
-Read Revoke read permission
-ReadACP Revoke read ACP permission

Installation

Powershell Snap-In must be registered and added to console.

Registering Snap-In

If the PowerShell is installed prior to installation of CloudBerry Explorer, you do not need to install Snap-in. Otherwise, run the following command in the CloudBerry Explorer installation folder (c:\Program Files\CloudBerryLab\CloudBerry Explorer for Amazon S3):
C:\Windows\Microsoft.NET\Framework\v2.0.50727\installutil.exe CloudBerryLab.Explorer.PSSnapIn.dll

Note: For x64 the command must be like : C:\Windows\Microsoft.NET\Framework64\v2.0.50727\InstallUtil.exe "C:\Program Files (x86)\CloudBerryLab\CloudBerry Explorer for Amazon S3\CloudBerryLab.Explorer.PSSnapIn.dll"

Note: For PRO version the default installation folder is "C:\Program Files\CloudBerryLab\CloudBerry S3 Explorer PRO"; on x64 - "C:\Program Files (x86)\CloudBerryLab\CloudBerry S3 Explorer PRO"

Note: You can do this from command line or PowerShell.

You can verify that the CloudBerry Explorer Snap-in is registered. Run the following command:
Get-PSsnapin –Registered
PowerShell displays registered Snap-Ins. Check that CloudBerryLab.Explorer.PSSnapIn is in the list.

Adding Snap-In to console

You can check that CloudBerry Explorer Snap-in is registered by running command above.
To add Snap-In to console run the following command:
Add-PSSnapin CloudBerryLab.Explorer.PSSnapIn
Now new command will be available.

Exporting console configuration

You should run Add-PSSnapin command anytime you start PowerShell or you can save configuration using the following.

• Run PowerShell.
• Add Snap-In to console.
• Run the command: Export-Console CloudBerruExplorerConfig

CloudBerruExplorerConfig is the name of a console file to save configuration. To start the PowerShell from a saved configuration run the command:
C:\Program Files\Command Shell> PS -PSConsoleFile CloudBerruExplorerConfig.psc1.
CloudBerry Explorer commands will be available.
