An OpenTP1 file system can be backed up by the filbkup command. OpenTP1 file system backup should be performed periodically for protection against possible OpenTP1 file system errors.

When the filbkup command is executed, the attributes of the individual OpenTP1 files are also backed up, including the record length, number of records, and most recent update date and time.

Only a single OpenTP1 file system can be backed up into a backup file. To back up multiple OpenTP1 file systems, a separate file must be specified for each OpenTP1 file system.

It is also possible to specify the names of selected OpenTP1 files for backup processing (this option is usually used in collecting maintenance information).
