Method and a computer system for synchronising backups of objects and of meta data about the objects
First Claim
1. A method for synchronizing a backup of objects stored in a data management system with a backup of meta data about the objects kept and maintained by a second system, further comprising:
- for each file the second system is using for maintaining the meta data, inserting a corresponding data link value pointing to the associated file in an administration table;
backing up the objects together with the administration table, wherein the backup automatically backs up each file for which the corresponding data link value has been inserted into the administration table; and
removing the data link values from the administration table.

Abstract
Techniques are provided for synchronizing a backup of objects stored in a data management system with a backup of meta data about the objects kept and maintained by a second system. For each file the second system is using for maintaining the meta data, a corresponding data link value pointing to the associated file is inserted in an administration table, the objects are backed up together with the administration table, wherein the backup automatically backs up each file for which the corresponding data link value has been inserted into the administration table, and the data link values are removed from the administration table.

11. A computer system comprising:
-
a data management system with objects stored therein, said data management system supporting backup and recovery;
a system unit referencing external data and enabling the data management system to have control of the external data without moving the external data, wherein the system unit is coupled to the data management system;
a second system external to the data management system maintains meta data about the objects stored in the data management system and synchronizes a backup of the objects with a backup of the meta data, wherein the second system is coupled to the system unit; and
wherein the system unit, for each file that the second system is using for maintaining the meta data, inserts a corresponding data link value pointing to the associated file in an administration table, backs up the objects together with the administration table, wherein the backup automatically backs up each file for which the corresponding data link value has been inserted into the administration table, and removes the data link values from the administration table. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19)

20. A computer program product with a computer-readable medium and a computer program stored on the computer-readable medium with a program code, wherein when the computer program is run on a computer, the program code is suitable for carrying out:
-
for each file the second system is using for maintaining the meta data, inserting a corresponding data link value pointing to the associated file in an administration table, backing up the objects together with the administration table, wherein the backup automatically backs up each file for which the corresponding data link value has been inserted into the administration table, and removing the data link values from the administration table.

22. A computer-readable medium with a computer program stored thereon, the computer program comprising a program code which is suitable for carrying out:
-
for each file the second system is using for maintaining the meta data, inserting a corresponding data link value pointing to the associated file in an administration table, backing up the objects together with the administration table, wherein the backup automatically backs up each file for which the corresponding data link value has been inserted into the administration table, and removing the data link values from the administration table. - View Dependent Claims (23, 24, 25, 26, 27, 28, 29, 30)
