In cloud storage, data durability is maximized, and it is practically easier to distribute data on any scale. This method also offers multi-layered data redundancy, which completely throws away the possibilities of data loss. As we have discussed the advantages of the cloud over LTO in redundancy and distribution, it is also implied that data recovery rates are incredibly fast in the cloud.
The lack of complex logistics makes data recovery almost effortless. In LTO, data recovery is made manually, and it involves a ton of logistics that can slow down the process exponentially. This can cost you several unnecessary work hours, which is a big no for any business. Upgrading an LTO system involves hardware maintenance and re-indexing data, which can spike the total cost of ownership TCO.
Constantly refreshing LTO technology involves upgrading tape libraries, drives, and archival software, which is much work. In a cloud system, upgrades to the infrastructure are done in the background, and it barely requires anything from you.
Rewriting data every time a new version of LTO pops up is practically impossible with large-scale data. There is a serious lack of compatibility in both forward and backward streams, which is a major drawback.
In cloud storage, the object protocols are very mature, and it expedites both software and hardware updates without any obstacles. The cloud storage infrastructure has made it very feasible to incorporate artificial intelligence in indexing and enhance processes.
For instance, creating transcripts with audio recognition, metadata addition, and other similar tasks can be done without any hassle using AI. LTO, on the other hand, is limited by the technology it was built upon. There is practically no room for any integration that can improve efficiency in LTO storage.
As we dive deep into the pros and cons of LTO and Cloud storage, it is obvious that the cloud has the upper hand in accessibility, safety, and other important aspects. Cloud storage systems are revolutionizing the digital world.
Besides, the stellar advantages provided by the cloud's scalable, transparent and secure architecture are making a point to replace LTO with cloud in any data-intensive sector. You might argue on the grounds of setting up cost and claim that LTO is better than cloud storage.
This might serve true for a very small scale, but universally, the cloud beats LTO in every possible way. Want to learn how to improve your media management practices? Click below to speak with an expert today! ProMAX vs. Editshare ProMAX vs.

The other historical problem with tape was the manner in which files were stored on it. A tape drive, much like an unformatted hard disk, provides nothing more than a huge list of stored numbers. Usually, on a hard disk, each of these sectors is bytes long about text characters worth , and has a unique address which can be used to store or retrieve its contents.
To take this and turn it into the normal structure of files and folders that we see on modern computers requires a file system, the system that allows groups of sectors to be stored together and considered as a file, which can then be organized into a folder, among many other features.
There are various ways to do this; Apple Macs, Linux machines and Windows PCs do it differently, which is why hard disks created on one aren't always readable on the other. Until LTO5, however, there was no equivalent system for tape drives and various, often incompatible approaches were used. Now, however, we have the linear tape file system LTFS which provides the familiar configuration of files and folders and allows files to be stored and retrieved at will.
There are necessarily a few limitations to this. Ordinarily, when a file is deleted, the space it used is freed up for future use. This may mean that gaps can appear in the list of sectors that actually contain data and those gaps won't be the same size as files to be written in future. Because of this, files can be fragmented over several clusters of sectors, and reading the file requires the device to skip around and reassemble them.
This is not ideal on hard disks, but it's manageable. On tape, with the need to physically shuttle up and down the tape, it would create an unreasonable performance problem, so deleting files doesn't actually free up space.
Reformatting the tape does, of course, make all the space available again. The only other issue with putting a file system like this on a tape is that maximum performance is only achieved if the files are read in the same order they're written. This is reasonable; it's tape; that's how it works, and it's both a convenient way to do it given the chaotic historical alternatives and a very welcome piece of standardisation. The LTFS driver software is a free download. Beyond that, it's very straightforward; tapes appear in the same way as any storage device when inserted and require formatting via a supplied utility.
Formatting is quick there is no slow sector-by-sector going over of the tape media and once that's done, things operate in more or less the same way as a hard disk.
Ejecting a tape is as simple as ejecting a flash storage card. In the interests of complete disclosure, there were a few minor wrinkles getting the drive to recognise fresh, unformatted tapes after ejecting a formatted tape, but these issues were quickly solved with a power cycle and didn't happen again.
One thing we noticed when trial-testing the previous version of LTFS on an LTO5 drive is that small file performance could be poor, with the drive audibly ramping the tape transport speed up and down for each file. This is important because it is directly relevant to file-per-frame video storage, where the individual files may be small eight megabytes for some HD video frames , but the numbers of them are huge.
The performance problem here appears to be more or less fixed. While small-file performance still isn't quite as snappy as that when writing for instance, large Quicktimes of a few dozen gigabytes each , it's well within the sort of range that could be explained by performance variations in the disk feeding the tape drive.
LTO is a backup medium, designed to store large amounts of data securely for long periods. Equally, a stack of hard disks actually has a notoriously short shelf life. All devices and media are compatible with each other following a compatibility matrix. Up to LTO-7, drives could read two generations backward and write one generation backward e.
Starting with LTO-8, this was changed to read and write one generation backward. The half-Inch 12,65mm Tape was used since the s to store data. Multiple vendors and formats competed, while none were compatible with the other. LTO-1 was released in The most recent generation, LTO-8, was released in December The LTO cartridge has a single reel of tape. When in the tape drive, the tape gets wound into the drive to the take-up reel. Tape length started with m and is now at m per cartridge.
Capacity usually doubles from one generation to the next and now is at 12TB native. The roadmap for future generations extends to LTO Data is written on the tape in sequential order, one file after the next.
