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; }
The struct idates describes an entry in the /etc/dumpdates file where the backup history is kept. The fields of the structure are:
id_name | The name of the file system. |
id_incno | The level number of the last backup. |
id_ddate | The date of the incremental backup in system format. |
MAXNAMLEN | The maximum value of this variable is 255. |
This file is part of Base Operating System (BOS) Runtime.
/etc/dumpdates | Specifies the path name of the symbolic link to the dumpdates file. |
The backup command, rdump command.
