I am looking for a utility to upload an 80 GB file (a VHD) to Azure blob storage. I have tried Azure Management Studio from Cerebrata which is a good tool, but the upload keeps failing. I tried Azure Storage Explorer also, without success. My internet provider is ATT Uverse and I get 16 Mpbs down and 1.4 Mbps up according to speedtest.net. This should be enough to upload the file in a few days, if my math is correct.
81,920 MB
1.4 Mbps= .175 MB/s
5.4 days
Is there a way to break a file into pieces and upload in parts to azure blob storage? Am I going to have to write my own C# client to upload the file? I could do this, but I was hoping to find a good tool that would do it for me.
Did you tried AzCopy tool? This tool is very fast. Check here :

If that doesn't work, you have to write code to split the file and upload it.
You can take help of the below code :

You might want to check out this post: Uploading a file in Azure Blob Storage.
It explains how you can upload any file to Blob storage with a PowerShell script.
I take it you've tried using the Azure Powershell to do it? the Add-AzureVhd command?
For more info check this out:
http://www.windowsazure.com/en-us/manage/windows/common-tasks/upload-a-vhd/
Having said all this, I've tried to upload a 57GB vhd using this method and it keeps failing after about 40 mins or so, so I'm constantly having to resume the process. It worked fine 1st time for a test 20MB vhd I created though.
UDPATE: I got it to work eventually though powershell, the problem for me was the vhd file I was trying to upload, not the process I was using.

I was using Azure VM and my subscription was disabled. there were some files that I was working on in the last few days without backup on my local device. now I got a link to the machine VHD but it's too big and my connection is very slow. Is there is any way to download only my files from that link without downloading the whole file?
my file is almost 1 MB and the image is 127 GB. I know that the best solution is to make another subscription but I only have a pre-paid card now any they don't accept that
If you have VM's backup you can perform a file level restore. If you have 'just a link' to VHD file unfortunately there is nothing you can do to download single file - sorry.
So I am trying to create a powershell script which will upload a large (> 4GB) .Bak file to Azure Blob Storage but currently it is getting hung. This script works with small files which I have been using to test.
Originally the issue I was having was the requirement to have a Content-Length specified (I imagine due its size) so I now calculate the file size of the .bak file (as it varies slightly each week) and pass this through as a request header
I am a total powershell newbie, as well as being very new to Azure blob. (NOTE: I am trying to do this purely in powershell, without relying on other tools such as AzCopy)
Below is my script
Powershell Script
Any help would be greatly appreciated..
There are a few things to check. Since file is big, are you sure it isn't uploading? Have you checked network activity in performance tab of task explorer? AzCopy seems like a good option too that you can use from within Powershell, but if it's not an option in your case, then why not to use native AZ module for Powershell?
I suggest you using Set-AzStorageBlobContent cmdlet to see if it helps. You can find examples at Microsoft docs
I am uploading files with AZCOPY (one by one as and when they are provided) to Azure Datalakes gen 2 and keep a track with Storage explorer and individual log of each file.
There have been 6253 file uploads and Storage explorer shows the same along with number of logs for each file upload
But when i use AZCOPY LIST it gives me 11254.
Making it difficult to script and automate.
Is there a logical explanation for this?
There is no access issue, in fact the same AZCOPY is working on copying the files
I have tried to redownload if that makes sense
This is a known bug, scheduled for fixing in our next release: https://github.com/Azure/azure-storage-azcopy/issues/692
Some large disks containing hundreds of 30GB tar files have been prepared and ready to ship.
The disks have been prepared as BLOB using the WAImportExport tool.
The Azure share is expecting files.
Ideally we don't want to redo the disks as FILE instead of BLOB. Are we able to upload as BLOBs to one storage area and extract the millions of files from the tarballs to a FILE storage area without writing code?
Thanks
Kevin
azcopy will definitely do it and has been tested. We were able to move files from blobs to files using the CLI in Azure with the azcopy command.
The information provided below was proven not to be true.
Microsoft Partner told me yesterday there is no realistic way to convert Blobs to Files in the above-mentioned scenario.
Essentially, it is important to select either WAImportExport.exe Version 1 for BLOBS or WAImportExport.exe Version 2 for files. Information on this can be found at this location.
The mistake was easily made and done so by a number of people here: the link to the tool sent was to the binary version 1. Search results tended to direct users to version 1 but version 2 only appears only after deeper dig. Version 2 - seems to be an afterthought my Microsoft when they added the Files option to Azure. It's a pity they didn't use different binary names or build a switch into version 2 to do both and delete the version 1 offering.
I've written a powershell script to upload from a windows system to an Amazon S3 Bucket. The script successfully uploads all files, except those over 5Gb. I have the Cloud Berry Explorer Pro license which allows for multipart upload on files up to 5TB. However there is no flag for multipart on the powershell snapin documentation. Cloudberry support directed me here as they only support the GUI not the powershell snapin. When running my script I get the error
"WARNING: Your proposed upload exceeds the maximum allowed object size (5 Gb)".
So question is, does anyone know if there is a command line option, or another way to enable multipart upload to Amazon S3 using Cloudberry Explorer Pro's Powershell Snapin?
Set-CloudOption UseChunks=true
I'm looking for the same in Powershell.
I believe in GUI, the original chunking mechanism has been depreciated. I have not tested myself, but I assume Powershell option UseChunks=true is still using the old mechanism? If so, files may be split into multiple parts and not automatically recombined when they arrive on S3. The new GUI Multipart Upload facility sorts this all out for you.
Annoyed Cloudberry still advertise Powershell as a component of Explorer (Free & Pro), but don't support it, even for fully paid up PRO support customers.
We did purchase the cloudberry explorer pro license for the native multipart upload capability, but we wanted to automate it. I believe based on their documentation that the old chunk method is deprecated in favor of their new multi-part functionality. We wound up testing the options listed in the powershell documentation. Those options are as follows:
Set-CloudOption -UseChunks -ChunkSizeKB
"Defines a size of chunk in KB; files larger than a chunk will be divided into chunks."
We verified that this was successfully uploading files beyond the 5GB restriction to our S3 bucket. I attempted to get a response from Cloudberry as to whether this was the old Chunking method or the new Multi-Part method, but I was unable to get a straight answer. They confirmed that because we were using pro, this powershell option was supported, but they failed to confirm which option the powershell command was using.
From what I can tell it appears that Cloudberry's legacy chunking mechanism would actually just break the file into individual files and thus would appear in S3 as multiple files. The Chunk Transparency mechanism in Cloudberry Explorer would allow the multiple chunks to appear as a single file in the Cloudberry Explorer GUI only. Since I can see the file as a single file on the S3 side, I'm assuming that the powershell option uses the new Multi-Part functionality and not the legacy Chunking functionality. Again I was not able to confirm this through Cloudberry so it's speculation on my part.
However, I can confirm that using the powershell options above will get you around the 5GB upload limit when using powershell.
