My release pipeline uploads to blob storage using
Azure File Copy
I want to delete the existing files in the blob before copying over the new files.
The help shows that
cleanTargetBeforeCopy: false
only applies to a VM
(since it is a release pipeline I can't edit the YAML anyway)
The tool tip for Optional Arguments shows
Optional AzCopy.exe arguments that will be applied when uploading to
blob like, /NC:10. If no optional arguments are specified here, the
following optional arguments will be added by default. /Y,
/SetContentType, /Z, /V, /S (only if container name is not $root),
/BlobType:page (only if specified storage account is a premium
account). If source path is a file, /Pattern will always be added
irrespective of whether or not you have specified optional arguments.
I want to delete the existing files in the blob before copying over the new files.
If you want to override the blobs during run copy file task, we neeed to add another optional argument at all.
As you mentioned that if we don't add optional Arguments. /Y paramter is added by default.
The blobs will be replaced by the new files by default when run Azure Copy Files task.
If you want to clean the container, you could use the Azure Powershell command to delete the container and recreate the new one before run the Azure copy file task.

My agent is installed in C:/azagent, as it was by default after running the powershell script created for me when creating a new deployment group.
My build artifact "drop" gets placed in C:\azagent\A1\_work\r2\a\_TransactionImportTurkey-Test\drop
It is here i run into issues. I want to copy the files over to V:\Program\TransactionImportTurkey\TransactionImportApp but get this error:
enter image description here
I have no issues copying the files when i use a filepath within C:/ root directory.
This is the YAML-file :
enter image description here
How can I make a release to another root directory than C:/ ?
I would do four things here:
First, ensure that your Azure Pipelines Agent is running under a domain account and not a local one.
Second, ensure that the target folder grants write privileges to that account.
Third, run net use to get the target mapping for V:
Fourth, change the target path for your copy to reference the path by the UNC mapping for V:, so instead of V:\Program\TransactionImportTurkey\TransactionImportApp, it would be \\TargetServerNameOrIP\PathToTargetShare\Program\TransactionImportTurkey\TransactionImportApp
I have a "copy data" activity in Azure Data Factory. I want to copy .csv files from blob container X to Blob container Y. I don't need to change the content of the files in any way, but I want to add a timestamp to the name, e.g. rename it. However, I get the following error "Binary copy does not support copying from folder to file". Both the source and the sink are set up as binary.
If you want to copy the files and rename them, you pipeline should like this:
Create a Get Metadata active to get the file list(dataset Binary1):
Create For Each active to copy the each file:#activity('Get Metadata1').output.childItems:
Foreach inner active, create a copy active with source dataset
Binary2(same with Binary2) with dataset parameter to specify the source file:
Copy active sink setting, create the sink Binary3 also with
parameter to rename the files:
#concat(split(item().name,'.')[0],utcnow(),'.',split(item().name,'.')[1]):
Run the pipeline and check the output:
Note: The example I made just copy the files to the same container but with new name.
Is there an option to handle the next situation:
I have a pipeline and Copy Files task implemented in it, it is used to upload some static html file from git to blob. Everything works perfect. But sometimes I need this file to be changed in the blob storage (using hosted application tools). So, the question is: can I "detect" if my git file is older than target blob file and ignore this file for the copy task to leave it untouched. My initial idea was to use Azure file copy and use an "Optional Arguments" textbox. However, I couldn't find required option in the documentation. Does it allow such things? Or should this case be handled some other way?
I think you're looking for the isSourceNewer value for the --overwrite option.
--overwrite string Overwrite the conflicting files and blobs at the destination if this flag is set to true. (default true) Possible values include true, false, prompt, and ifSourceNewer.
More info: azcopy copy - Options
Agree with ickvdbosch. The isSourceNewer value for the --overwrite option could meet your requirements.
error: couldn't parse "ifSourceNewer" into a "OverwriteOption"
Based on my test, I could reproduce this issue in Azure file copy task.
It seems that the isSourceNewer value couldn't be set to Overwrite option in Azure File copy task.
Workaround: you could use PowerShell task to run the azcopy script to upload the files with --overwrite=ifSourceNewer
For example:
azcopy copy "filepath" "BlobURLwithSASToken" --overwrite=ifSourceNewer --recursive
For more detailed info, you could refer to this doc.
For the issue about the Azure File copy task, I suggest that you could submit a feedback ticket in the following link: Report task issues.
I am trying to add a task to delete files with specific type from source folder and all the sub folders using delete task in Azure DevOps pipeline.
Delete task:
https://learn.microsoft.com/en-us/azure/devops/pipelines/tasks/utility/delete-files?view=azure-devops doesn't seem to provide any information on the patterns.
I have tried following combinations but none of them worked.
(.xyz)
(.xyz)
*.xyz
*.xyz\
my expectation is to delete files with .xyz type from all the sub folders.
Try setting:
**/*.xyz
As the Contents variable value.
The full range of pattern filters is described in the documentation here.
Using AzCopy.exe, I am able to copy over an entire container successfully. However, I cannot figure out how to copy over a blob where the name includes a folder structure. I have tried the following:
.\AzCopy.exe /Source:https://sourceaccount.blob.core.windows.net/container /Dest:https://destaccount.blob.core.windows.net/container /SourceKey:sourceKey== /DestKey:destKey== /S /Pattern:CorruptZips/2013/6
While also changing the /Pattern: to things like:
/Pattern:CorruptZips/2013/6/*
/Pattern:CorruptZips/2013/6/.
/Pattern:CorruptZips/2013/6/
And everything just says that there are zero records copied. Can this be done or is it just for container/file copying? Thank you.
#naspinski, there is the other tool named Azure Data Factory which can help copying a folder from a blob storage account to another one. Please refer to the article Move data to and from Azure Blob using Azure Data Factory to know it and follow the steps below to do.
Create a Data Factory on Azure portal.
Click the Copy Data button as below to move to the powercopytool interface, and follow the tips to copy the folder step by step.
Took me a few tries to get this. Here is the key:
If the specified source is a blob container or virtual directory, then
wildcards are not applied.
In other words, you can't wildcard copy files nested in a folder structure in a container. You have two options:
Use /S WITHOUT a pattern to recursive copy everything
Use /S and specify the full file path in your pattern without a wildcard
Example:
C:\Users\myuser>azcopy /Source:https://source.blob.core.windows.net/system /Dest:https://dest.blob.core.windows.net/system /SourceKey:abc /DestKey:xyz /S /V /Pattern:"Microsoft.Compute/Images/vmimage/myimage.vhd"
EDIT: Oops, my answer was worded incorrectly!
Please specify the command without /S:
AzCopy /Source:https://myaccount.blob.core.windows.net/mycontainer1 /Dest:https://myaccount.blob.core.windows.net/mycontainer2 /SourceKey:key /DestKey:key /Pattern:abc.txt
You can find the information from "Copy single blob within Storage account" in http://aka.ms/azcopy .
