Specify a folder without files and sub-folders as the backup folder. If the specified
backup folder does not exist, it is created.
Do not change the backup folder structure. If changed, restoration may not be
processed correctly.
Do not change the content of the backup file of Central Admin Server settings. If the
backup file content is changed and restored, processes related to the Central
Admin Server may operate improperly.
All files in the installation folder are deleted when the Central Admin Server software
is uninstalled. Therefore, save all backup files to a location other than in the
installation folder.
Before executing the AmBackup.exe command, confirm that the storage disk has
sufficient free space. If there is not enough free disk space, an incomplete file may
be saved.
The required free capacity is approximately twice the free capacity under the [Data]
folder in the installation folder.
