Backup Error on Sangfor Platform

Jarvis Holbrook

Happy Friday, everyone!
I encountered an error while performing a backup on the Sangfor platform. Could anyone help check what might be causing this?

Error Log:

Web:
ERROR:1#Generic error, [ERROR:644#dynamic partition exists]: parse main partition error.
Log:

[ERROR:644#dynamic partition exists]: parse main partition error.
[ERROR:644#dynamic partition exists]: parse MBR partition information error.
[ERROR:644#dynamic partition exists]: parse GPT partition error.

Has anyone experienced a similar issue? Thanks in advance for your help!

It might be related to some limitations on the Sangfor platform. Dynamic and pre-allocated disks don’t support zero-transfer from the source side, so the log shows messages about analyzing dynamic partitions.

Tobias Whitmore Oh, I see. So how can we resolve this?

Jarvis Holbrook This message is usually related to certain limitations on the Sangfor platform.
For pre-allocated and dynamic disks, zero-transfer from the source side is not supported at the moment, so similar logs may appear in the job or run log — they can usually be ignored for now.
It’s a good idea to keep an eye on later logs, though. If you see an error like
load timepoint self explan file error, self_explan_file_path
in the same VM task, please check whether the corresponding self-describing file is valid.
