The problem is related to the following CAR:

CAR00040795 CAR - Backup of PostGreSQL fails when using CJK on Windows
The problem is due to the fact that Control-M expects to get a time with AM\PM but the machine returns Chinese characters.

Workaround:

1. Make a backup of the file dbu_hot_backup.vbs which is located in "<EM_HOME>\Default\bin\DBUtils\DBUData\scripts"

2. Edit the file dbu_hot_backup.vbs

3. Search for "datevalue(date)" string and remove the "& timevalue(time)" so the line will look like the following:

backup_label = datevalue(date)

4. Save and Exit the file.

5. Run the backup again.
