1. Background: Field of the Invention
The present invention is related generally to electronic/software data backup and more particularly to simultaneous and seamless examination of such data backup activity performed across a plurality of data backup software programs.
2. Background of the Invention—Description of Prior Art
Most data backup software devices in use today provide for the repeated, regular electronic transfer, over a network, of data from the point at which it is in regular use to a medium, such a magnetic tape, for the purposes of securing a fall-back situation should damage occur to the original data. Included in the list of such software programs, are programs that work on relatively small amounts of data, sometimes on a one-computer-to-one-tape-drive basis, and others that work on very large amounts of data, with banks of tape drives that are used to back up data from potentially thousands of computers connected to a network. Mostly, these data backup software products use what is known as a “client/server” model. In the context of data backup, this means that there is one computer (the “server”) that controls and manages the actual data backup activity, and other computers (the “clients”) that get backed up by the “server”. In this scenario, the data backup tape drives are usually connected directly to the backup “server”. There is also usually more than one backup server, each of which is responsible for the backup of data of numerous clients.
A central function of the activity of data backup is the ability to “restore” data in the case of damage to the data that is in use. The backup server computer usually controls this restore process. Understandably, the time it takes to recover data, and the confidence that the data recovery process will succeed, are two critical aspects of the data backup and restore function as a whole. Disk drive capacities and data volumes, and consequently the volumes of data to be backed up, have historically been increasing at a greater rate than the backup server speed, tape drive capacity and network bandwidth are increasing to handle it. Accordingly, new technologies have been added to help. Such new technologies include fiber-optic cables (for fast data transfer across the network), faster chips, tape drives that handle more tapes, faster tape drives, “Storage Area Networks” and so on. The activity of data backup has become more and more critical, as the importance of the data has increased. At the advent of the desktop “revolution”, that is, when people first started using personal computers (PCs), almost every piece of important data was still stored on one, single computer, possibly a mainframe or a minicomputer. As the numbers and types of computers proliferated, particularly on the desktop, and the purpose for which these desktops were now being used, making the data on such computers increasingly valuable, many different products designed to backup data were created and put into the marketplace. Now, there are some 50 or more data backup products in use by organizations and private individuals.
Generally, but not always, such data backup software devices (products) have a reputation for being difficult to use. When there is an exception to this, the data backup software product often has other, perhaps related, limitations (e.g. the amount of data is can back up is small). Not all data backup software devices perform the same function. Thus, it is frequently necessary to have two or more different types of data backup software programs in use within the same organization, especially in large organizations. Anecdotally, one company has as many as 17 different data backup software devices in use somewhere in their organization. This is referred to as fragmentation. In large organizations, is has become necessary to hire expensive expertise to manage such large data backup and restore services. The more varied their data backup devices, the more expensive this becomes. Also, for large organizations, it has become increasingly likely that scheduled data backup activities will fail. Because of the extra complexity of running a variety of data backup software devices, and because of the sheer number of data backup activities that need to take place regularly, failed data backups often go unnoticed in a sea of less-relevant data backup information.
An additional problem is that beyond a certain number of hours, perhaps minutes, if identifying a failed data backup takes too long, then it often becomes too late for meaningful corrective action to be taken. As a result, large organizations often take an expensive “best guess” approach. Anecdotally, the level of confidence that large organizations live with regarding data backup success is said to be about 80%. In other words, it is expected that no more that 4 out of 5 data backups will be successful. Almost every large organization will relate experiences where data was lost because they mistakenly believed the data was been backed up.
In the marketplace today there are several data backup reporting products available. Each works with only one data backup software device. There are no known patents relating to either of these two products.
1. Legato GEMS Reporter™, which provides trend analysis and text-based failures analysis. This product works with Legato NetWorker. It is built to handle up to approximately 4 or 5 average-sized backup servers.
2. Veritas Advanced Reporter™ 3.2 form Veritas is similar to GEMS Reporter.
3. SAMS Vantage™ provides statistical report from data backup activity of Computer Associates ArcServeIT product.
Accordingly, an OPEN relational database is required to enable the cross-referencing of historical data backup activity across a plurality of data backup software devices. This is because to examine the data, 3
rd
party reporting/querying tools are generally used, and such tools generally only work with OPEN relational databases.
SUMMARY
In accordance with the present invention an automated software device for the extraction of historical records of data backup activity from a plurality of data backup software devices, and the storing of those records in a general-purpose relational database.
OBJECTS AND ADVANTAGES
Accordingly, besides the objects and advantages stated in our above patent, several objects and advantages of the present invention are:
(a) Provides the ability to automate, requiring little or no further intervention, the regular and scheduled extraction of historical records of data backup activity from a plurality of data backup software devices.
(b) Consolidates and cross-references the historical records of data backup activity into a single database, thereby providing the ability to create reports on data backup activity from a plurality of different data backup software devices.
(c) Exposes those consolidated and cross-referenced historical records of data backup activity in an open relational database, thereby enabling users of the invention to use 3
rd
party reporting/querying products to create their own, perhaps unique reports.
(d) Provides such consolidation of historical records of data backup activity without the need to install additional software devices at the source of those data records.
