Reading backups from the disks is also easier compared to tapes that need to be physically mounted and switched when they are full. Using software-defined storage, disks can be pooled so that writing backups to the disks is simplified since data can be split or mirrored across multiple disks for flexibility and resiliency. Technical Benefits of Disk Storageĭisk storage provides IT departments with agility, particularly in a modern and highly-virtualized datacenter. #USB BACKUP TAPE ARCHIVE#These benefits are likely only going to make sense for organizations looking to archive their data that do not expect that they will need to regularly (or ever) access it again. #USB BACKUP TAPE OFFLINE#The significant advantage of having genuine offline storage is that it is resilient to ransomware attacks since the data is physically isolated from the rest of the IT infrastructure. #USB BACKUP TAPE MANUAL#Previously this was a manual operation performed by the IT staff, but with modern technologies, this can be automated. Once tape storage has been written to and is full, it must be physically moved to a separate archiving location, and it is considered offline and inaccessible until it is remounted on the tape drive. However, they may need to be uncompressed or decrypted from the same device that wrote them, which is good for security but bad for compatibility. Modern tape storage solutions support reasonable compression and encryption technologies. Read and write speeds on tape can be very fast, but only when the data is optimized, and there are no bottlenecks that affect its throughput. Businesses with compliance requirements that have to archive data for a long period of time, such as pharmaceutical companies, hospitals, or universities, may opt to use tape drive for its cost savings. The hardware cost of tape storage is cheaper than using disks, particularly SSDs, making it a good choice for organizations to retain a significant amount of data. It is very similar to storing and playing music from a cassette tape, although it has much greater performance. A tape storage stores data on thin film and needs a mechanical drive to spin the tape and a drive head to read the data. Magnetic tapes were the first mainstream storage device offered to the IT industry and are still available today, with the most recent standard, LTO-8, being published in 2017. This blog will explore the tradeoffs between these hardware solutions for backing up enterprise data. Perhaps a good comparison is that backups give you flexibility like using digital music on your computer, while tape storage is similar to playing music on cassette tapes. However, if you have archival storage needs with very irregular access to the data, then tape storage has some benefits. Disk storage! That is an easy question because using a disk for backup is clearly the best medium, especially in the modern software-defined datacenter, as it provides technical, reliability, security, ease-of-use, and ecosystem advantages. ![]()
