preScriptPath

Only vaild for the linux system when AppConsistent is true. Apply the freeze script path (e.g. /tmp/prescript.sh). prescript.sh scripts must meet the following conditions: in terms of permissions, only root, as the owner, has read, write, and execute permissions, that is, 700 permissions. In terms of content, the script content needs to be customized according to the application itself. This indicates that this parameter must be set when creating an application consistency snapshot for a Linux instance. If the script is set incorrectly (for example, permissions, save path, or file name are set incorrectly), the resulting snapshot is a file system consistency snapshot.
