![]() ![]() Download our whitepaper on data tape backup now and separate the fact from the fiction.By Jessie Reed Magnetic Tape Backup: Choose the Best Backup Practiceĭisk-based and cloud-based backups are more commonly used than backup to tape due to the benefits that they provide, such as continuous data protection and instant recovery. There are a lot of highly circulated myths about tape backup systems. For more information on how to reduce your backup and restore windows with mMultistreaming, download our whitepaper on multistreaming. As enough backup data becomes available in the buffer, the backup server sustains the data transfer speed. This ensures that the tape drive achieves maximum write speed. On the server, the complete backup data load is kept in the buffer, which allows the backup server to pick as many data packages from the buffer as the tape library can write. With client multistreaming, all backup data is transferred to the backup server within a short period of time. If the data rate should drop, the device may also reduce its read speed, thereby slowing down the backup. To make the best use of the high write speeds of the devices, the backup data is sent to the device at a constant data rate. With multistreaming (also known as multi-threading) the backup takes place at the maximum speed of a tape drive as it allows the data to be transferred in multiple parallel streams rather than in one long data stream. ![]() Using a tape drive in a tape library without being able to fully benefit from its capacity, simply does not justify the investment. If during the backup process only a single stream is writing to the tape drive, the backup cannot even begin to utilize the drives' full speed potential. They read or write at more than a hundred MB per second and several hundred GB per hour. Today's tape libraries achieve enormous writing speeds. If you have large amounts of data to store and want a fast, efficient, affordable storage method, our backup experts can help you explore the best tape backup software to use.
