PowerShell
• Creating a share
$c = New-AzureStorageContext <acc> <key>
New-AzureStorageShare <share> -Context $ctx
10
AzCopy
• Recursive copy
AzCopy G:\Backups\
https://acc.file.core.windows.net/share/
/DestKey:key /s
11
SMB
• Creating a mapped drive
net use Z:
\\acc.file.core.windows.net\share
/u:acc key==
• Persisting credentials
cmdkey /add:acc.file.core.windows.net
/user:acc /pass:key
12
SMB
• In Code (P/Invoke)
WNetAddConnection2 (Mpr.dll)
• In Code (Using RedDog.Storage)
CloudFileShare share =
client.GetShareReference("reports");
share.Mount("P:");
13
SMB
• Credentials: persisted per user
• Mapped drives: persisted per user context
• User can have 1 normal context
• User can have 1 elevated context (administrator)
• Use /runas to store credentials and map drives for
other users
14
REST
• Using the Storage Client Library
var fileClient = storageAccount.CreateCloudFileClient();
var share = fileClient.GetShareReference("reports");
if (share.Exists())
{
var dir = share.GetRootDirectoryReference();
var file = dir.GetFileReference("report.txt")
var content = await file.DownloadTextAsync();
}
