We can back up the files in a file store using the facilities of your operating system, or using a backup tool. A file store is a type of message store that directly uses files in a file system through the operating system. Use the facilities of your operating system or a backup tool to back up the log file, the permanent store file, and the temporary store file, which comprise a file store. For more information about these files, see Hints and tips for configuring file store size.
If you start backing up files while the messaging engine is still running, data might be corrupted.
You must treat the log file, the temporary store file, and the permanent store file as one unit; that is, any operations must be performed on all three files.
