This article addresses an issue where the configuration archival feature's transfer-on-commit functionality is failing on ACX7024 devices. The problem manifests as an inability to transfer archived configuration files to the specified remote location after a commit operation.

Configuration archival feature to transfer-on-commit is failing on lab ACX7024. 

Error messages in system logs indicating transfer failure:

Root Cause:

The issue stems from an incompatibility with password arguments in the curl command used for file transfer on EVO platforms.

Workaround:

Do not include the password node in the archival configuration command for EVO platforms.

Correct configuration syntax:
set system archival configuration transfer-on-commit archive-sites scp://username@host/path

Incorrect syntax (avoid using):
set system archival configuration transfer-on-commit archive-sites scp://username@host/path password 'SECRET-DATA'

If using FTP, ensure to use double slashes at the beginning of the destination folder: ftp://ftpuser:password@host//path

Verify the configuration: show system archival configuration

After applying the correct configuration, commit the changes: commit

Monitor system logs to confirm successful transfers after commits.
