Backup Files

The backup target directory contains a backup_list file that lists the NIS+ directory objects most recently backed up to this target directory.

Each of the subdirectories contain two files and a /data subdirectory. The three files are:

• data.dict. An XDR encoded file containing an NIS+ data dictionary for the NIS+ directory objects backed up to this directory.

• last.upd. A binary file containing time-stamp information about the NIS+ directory object backed up to this directory.

Each of the /data subdirectories contain one or more of the following files:

• root.object. An XDR encoded data file containing a description of the NIS+ root directory object. For example, /master1_bakup/doc.com/data/root.object.

• root_dir. An XDR encoded file containing a description of NIS+ objects contained in the root directory and server information for those objects. For example, /master1_bakup/doc.com/data/root_dir.

• table.directory. An XDR encoded file containing the data that was present in an NIS+ table at the time the backup was performed and also any data contained in any associated NIS+ log files. If there is an NIS+ table in the NIS+ directory object being backed up, a corresponding table.directory backup file will be created in the /data subdirectory for that directory object.

  For example, every NIS+ org_dir directory contains a hosts table so there will be a hosts.org_dir file in each target/org_dir.domain/data subdirectory. For example, /master1_bakup/org_dir.doc.com./data/hosts.org_dir

  User-created NIS+ tables present in a given directory object are backed up in the same way as the standard NIS+ tables.

• groups_dir. An XDR encoded file containing NIS+ groups information. This file is stored in the corresponding NIS+ groups_dir target directory.
