They each have multiple PBs of data on tape, as do a great many large financial institutions. Tape enables hyperscale: The big cloud providers rely on tape for high-volume, low-cost storage.Nightly, weekly, or incremental backups are made onto tapes stored onsite and offsite. Tape backup: Many still use tape as a direct data backup medium.The best approach is to offload it to a tape archive. That number could exceed 80% by 2025, he said. Moore said at least 60% of all data can be classified as archival. While most enterprise data is soon forgotten, it often can’t be deleted for compliance reasons or due to its potential future value. Long-term archiving: According to Fred Moore, president at Horison Information Strategies, data access again drops off rapidly after one month.There are several use cases for tape storage: See more: Dell: Storage Hardware Portfolio Review Tape Storage Use Cases It eats up far more floor space than tape storage. Tape is compact: Once you scale to hundreds of TBs, disk storage loses feasibility.Most analysts say disk storage falters badly after five years. Tape lasts longer: Tape can be stored for up to 30 years.Tape data transfers faster: Tape offers data transfer rates of 400 MB/sec, making it faster than disk.Economies of scale through tape enable cloud providers to offer their cheapest rates for lower-tier, tape-based archiving. Tape is cheaper: According to Gadomski, tape is three to four times cheaper to use than disk for long-term storage.“Tape has a significantly lower environmental impact as there is no need to have it constantly powered-on during data storage, thereby reducing CO 2 emissions generated during its lifecycle by 95% compared to hard disk drives (HDDs),” said Rich Gadomski, tape evangelist at FujiFilm Recording Media USA. Unlike disk, tape cartridges sit idle in automated libraries, consuming no energy until the time they are accessed. Tape is green: While disk arrays are energy hogs, tape storage offers a way to greatly reduce power and cooling requirements.Even larger cartridges are on the near horizon. One cartridge holds more than 60 years of video recording running 24 hours per day. Tape has high capacity: The newest LTO-9 tape cartridges hold 18 TB native and 45 TB compressed.If it’s offline, malware has no direct connection. Tape offers an air gap: With data breaches and ransomware attacks escalating, tape provides an air gap between data and the network (i.e., archived tape is retained offline either at an offline facility or as part of an automatic tape library).Tape continues to thrive due to a diverse collection of features and benefits. And that number is expected to rise even further. A record 114,079 PB of total LTO tape capacity (compressed) shipped in 2019, about four times more than shipped in 2009, according to the Tape Storage C ouncil. ![]() Tape capacity shipments have been steadily rising for more than a decade. For a while, it appeared that tape was indeed on the way out.īut like the mainframe computer, which “died” in the early nineties and is still in heavy use in large enterprise environments, tape found a new niche and quickly revived. The storage brand Data Domain even ran a “Tape is Dead” campaign that successfully weaned people off tape as the primary medium being used for backup at the time. Tape supposedly perished about 15 years ago when deduplication was being popularized. The tape storage market has had its ups and downs over the last couple of decades.
