Describes the format of the dumpdates file.
The /etc/dumpdates file holds filesystem backup information for the backup and rdump commands. The dumpdates file is maintained by using the -u option when performing file system backups. The following is the dumpdates data structure:
struct idates {
char id_name[MAXNAMLEN+3];
char id_incno;
time_t id_ddate;
}

history is kept. The fields of the structure are:
| id_name | The name of the file system. |
