Data Backup For Disaster Recovery And Faster Support
There are two main reasons you would want to backup your data: 1) to make a copy of your data in case the original data is lost and 2) to send in your data to CyberMatrix support when you encounter a difficult or unreproducible problem.
Many companies forget that their company relies on software for day to day operations. This software usually stores important data. If this data is not safely backed up and a disastrous event like a fire or even a hard drive crash occurs business operations can be seriously impacted.
Many companies will use specialized software to backup all important shared data. While these backup solutions tend to be very robust it is important not to become complacent. At least every month the backup should be inspected to verify that it is actually backing up all important data. There's little worse than restoring a backup only to find that data from one important application was not included in the backup.
Another important use for data backup is obtaining speedy application support. Complex software that uses a database to store large amounts of data is often virtually impossible to troubleshoot when it starts behaving improperly. To provide a solution to a technical problem, support technicians either have to have witnessed the problem before or they need to try to reproduce the problem themselves. If a problem can't be reproduced chances are that either the customer left out an important detail or that the problem is data-related. By sending in the problem data, support resolution time can often be reduced dramatically.
All CyberMatrix non-client/server desktop database software has a backup solution included with it. To back up data in this software simply choose Records | Backup Data from the Data Manager menu. This will create a time-stamped file in the application's Data\Backup folder. The created file is a zip archive file that can be opened in Windows. Customers with support issues can easily send in the file as an e-mail attachment.
For customers of CyberMatrix client/server software and web software, the data files will have to be manually zipped up and send to support. For newer software all files with the extension *.EDB* should be sent in. For older software all files ending in *.Dat, *.Idx and *.Blb should be sent in.
With CyberMatrix enterprise software all data is stored in large database servers like Microsoft SQL Server, MySQL or PostgreSQL. Because the data files are not directly accessible they cannot be backed up as with local database software. One way to backup your data within the software is to export key table data in CSV format. The CSV files can then be stored somewhere safe. This approach can be problematic since not only is it more time consuming but CSV files cannot handle carriage returns and other odd characters in memo fields. Binary data such as images also cannot be saved in a CSV file which is really just a delimited text file. So for enterprise software the best mechanism for data backup is to use the replication features of the particular database server used.
