Cloud back-up corrupted using windows task scheduler

Question

Hello,

We are trying to accomplish the following:

Scenario -

Automate the creation and removal of the backup file from the Atlassian cloud sites (JSW/Confluence) for rollback purposes, etc.

Issue -

Scenario I

Initiating the backup-jira-api-token.psi script from https://bitbucket.org/atlassianlabs/automatic-cloud-backup/src/master/.  Each time we run this script with Windows task scheduler the script will execute and download the backup.  However, the file is approximately half the size of a manually downloaded file and is corrupted.

Scenario II

If we run the powershell script manually, the file downloads and is the expected size and is not corrupted.

Root cause -

Unknown.

Could this be related to the scheduled task timing out?

Thank you in advance for any recommendations or thoughts you have with this issue.

Thanks,

Aaron

I had the same issue: manually in PowerShell ISE downloading is fast (approx. 150 Mbits) without interruption, in TeamCity script always downloads corrupted archive with "Received an unexpected EOF or 0 bytes from the transport stream". I noticed that the download speed in that case is much lower, approx. 4 Mbits. And I found the root cause:

turning off the progress bar did it for me. Progress bar can significantly impact cmdlet performance.
