The Oracle DIVArchive Export/Import features enables removing one (or more) tapes from one Oracle DIVArchive system and adding them to a second DIVArchive system. See Appendix B for Oracle DIVArchive options and licensing information.
The Export function (on the first DIVArchive site) generates metadata files that describe each tape selected for export, and then ejects the selected tapes from their current tape library.
You use the Import function to import the metadata, and then insert the ejected tapes into the second system. The archived objects on the exported tapes are then transferred to the second DIVArchive system.
All export functions and the Insert Tape command are executed from the DIVArchive Control GUI. The Import Tape function uses the command-line interface. DIVArchive enables more than one set of tapes (whether spanned or not) to be exported to and imported from a single file.
Newly imported objects will have only one instance - the instance residing on the tape(s) that was imported. You also have the option to import an object as an instance of another object already existing in the DIVArchive database. The Import Utility requires your specification of a target tape group for newly imported tape objects. The new objects will belong to the identified tape group and not the tape group of the DIVArchive system from which it was exported.
The Export/Import functionality is compatible with complex objects and has additional fields for the advanced formatting and functionality available in DIVArchive release 7.6.
Note:
The exported metadata from a DIVArchive 7.6 export cannot be imported into DIVArchive releases before 7.0. However, exported metadata created from releases of DIVArchive before 7.6 can be imported into the DIVArchive 7.6 system.DIVArchive 7.6 Export/Import includes the following new and enhanced features and functionality:
Tape Drive Encryption
Starting with the DIVArchive 7.6 release, tape drive encryption securely supports bulk tape migration between DIVArchive systems.
After enabling encryption on a tape group, all additional tapes added to the group will also be encrypted. However, any existing tapes in the group remain unencrypted if encryption was previously disabled.
You can view the encryption status of the tape on the Home, Tapes screen in the Control GUI.
See the Oracle DIVArchive Installation and Configuration Guide in the Oracle DIVArchive 7.6 Core documentation library for detailed configuration information.
Tape Compression
Tape compression is supported at the tape group level. When tape compression is enabled, any empty tape assigned to the group will have compression enabled, and instances written to the tape will be compressed. Tapes assigned to the group before compression was enabled remain uncompressed, and instances written to the uncompressed tape will be uncompressed.
To view all tapes with compression enabled, you must select the Home, Tapes icon in the Control GUI, and set the Compression filter to Y.
