D2D and Data Protector

For a customer it could be interesting to enhance the backup and recovery strategy and to do the backup (or parts of the backup) to disk first and to copy the data to tape later. The main advantage is the reduced time it will take to recover a single file, as the restore from tape is allways slower. Another point is whe doing the backup for slow servers, tape drives are underutilizied and blocked; no other backups can be done during this time. Backup 2 disk is nothing new with Data Protector and available since years, however when looking at current developments like deduplication, you should have closer look at the different solutions from other vendors. The HP solution might be the most interesting vendor in this situation as software and hardware are very good combined. Other vendors may offer hardware only or even worse can provide bad implemented software, HP is one step ahead

Physical Tape vs. Virtual Tape

In a modern Backup & Recovery infrastructure backup-to-disk solutions are used very often. But many customers need to look at capex and opex. With the implementation of modern deduplication technologies these expenses can be decreased very easily. However, to save money, you have to follow some rules, otherwise the backup-to-disk solution will not work as efficient as expected. The most important rules and a comparison of virtual and physical tape drives are listed below. More information and best practice tips can be found in “StoreOnce User Guides”. Basics: Physical and virtual tape principles are very different. Physical tape receives data that is optimized for a sequential data stream and writes the data in a serial format to a sequential target device. Virtual tape receives data in a random stream and to achieve top performance writes the data in a random format to a random access target device. Therefore the methods
