It has downward and upward compatibility. LTO tape technology has been around for more than a decade and is here to stay. It is a great option for data that has to be stored for many years due to legal requirements, such as financial business records. They are also immune to viruses and malware.

Even simultaneously, if you have more than one drive.Ĭonclusion: Tapes are much more durable than disks and are therefore portable for off-site storage.
Additionally, you can use the same tape library for your Backup as well as your Archive. Tape might be more expensive in its initial purchase price, but when looking at price per TB and overtime TCO, it is a great solution, especially for long time storage.

LTO is the only technology with a proven 30 year archive life.

This means you need the fitting hardware, as well as the right software to run a tape library.īut taking a second look at LTO technology is well worth it. It requires interfaces that cannot be found in all standard office hardware. Tape makes you leave your comfort zone, because you have to deal with a totally different type of technology than disk. How tape fits into your Sync, Backup & Archive strategy Moving around disk, however, is less than ideal, because it increases the risk of a failure even more.Ĭonclusion: For your Sync, Backup & Archive strategy, disk should not be the only storage medium you use, and it should probably not hold your archive. Additionally, you should move disks off-site in order to protect them from risks like fire, water, theft and so on. Depending on many factors, the question is not if it will fail, but rather when. The problem with disk is the fact that it fails. Disk also lets you access your data instantly. It can be used very easily, because necessary interfaces are already available. How disk fits into your Sync, Backup & Archive strategyĭisk has some obvious advantages. P5 helps implement a D2D2T workflow and maintain it on a daily basis. Disk and Tape are not interchangeable, and each comes with its own specific advantages and disadvantages. When planning your backup strategy, you need to incorporate the advantages of both storage types. But don’t judge too quickly tape is a solid medium for storing data. Oftentimes, disk is viewed as the modern and fast option, while tape is overlooked. When looking at different types of media like disk or tape, many have a set belief of what’s the right choice. This article is a stub and needs to be finished.While setting up your backup strategy, you inevitably face the challenge of picking the right storage media. NOTES: in the absence of " -go-into" the entire root would be backed up. To back up specific files in your home directory (filename will be myfiles.1.dar) use either ofĭar -create myfiles -root ~ -go-into file1 -go-into file2 The exclusion is to prevent recursive archiving of the archive. NOTES: the archive always decorates the name given with a slice number and ".dar". To back up your home directory to a file (./myhome.1.dar) use either ofĭar -create myhome -root ~ -exclude "myhome.*' a "root" is used as a reference, and only files under that root are archived.compression is applied to individual files, and may be suppressed for some file types.it is designed for archives that span volumes, in that archives are expected to comprise multiple "slices" and dar supports pauses to mount new volumes containing those slices.since the archives are seekable, selective extraction can be very fast.It is specifically optimized for disk (or other seekable) archives, with a few distinctive features If the operation should not affect all files in the root (or the backup) this is done through options.ĭar has several uses, but the most commonly used is to extract or to create dar archives. Unlike some other programs, "user targets" are not filenames but instead are names to be matched with configuration-file sections these are a rich family of filters and other qualifiers that affect the way dar works.
