by Julia Friedrich & Ibrahim Tannir When planning a data management strategy, there are a number of questions that need to be considered: Do I need an immediate failover solution? What is an acceptable backup frequency? What is the maximum retention period for past data? How can I make sure my data is safe in case of a natural disaster?
by Marc M. Batschkus An Archive is many things to many people. From reference to re-purposing, from monetization to service for clients, there are many perspectives on what an Archive can be and do. Since the perspectives vary so much, a closer look can reveal the potential hidden in this ancient term. Archivum was the name the Romans gave buildings that stored scripture rolls which were no longer needed for daily affairs. Although we no longer use scripture rolls, the mechanism hasn´t changed much. The files we put in an Archive today are those that are no longer needed for daily production. This means […]
by André Kühnemund When data security is key, a simple backup may not be enough to ensure data is available at all times, while a data sync does not offer long retention times and safe offsite storage. The solution is simple: Combine Archiware P5 Synchronize and P5 Backup for a Disk-to-Disk-to-Tape strategy and have the best of both worlds: immediate availability AND security. Backup to Disk to Tape (D2D2T) using P5 Synchronize and P5 Backup is a good way to leverage the advantages of both – some of which are: P5 Synchronize: Fast disk-to-disk copying of data Ability to maintain multiple file system snapshots […]
February 4, 2013 – Disk and tape drives both use a thin magnetic film layer to store Bits of your data, which are impressed on this film via a magnetic read/write head. A disk drive is produced in a super-clean dust-free environment and the disks that are coated with the magnetic film are enclosed in a hermetically sealed encapsulation. While reading or writing data, the disks are quickly spinning and the magnetic heads are not in direct contact with the disks, but are separated by a thin layer of air in between. In contrast, the tape drive’s head and the […]
December 3, 2012 – PresSTORE comes with a Backup and an Archive module. Both can use tape to save a copy of the data offline. So what exactly is the difference then? To Backup means to create a safety copy. Ideally, one will never need to use this copy. However, equipment fails and accidents happen. That is when you need to reach for the backup and recover either parts or all of your data. Accidents are generally twofold, either the online hardware fails and data in its most recent state that needs to be recovered gets lost, or the data […]
July 31, 2012 – LTFS makes the LTO technology accessible to a broader audience. However, if you plan to use it like a file system on a disk, you will end up being disappointed. To make the most of this technology, you need a basic understanding of how it works. The pitfalls of the LTFS technology are already described in its name: Linear Tape File System. The keyword here is “Linear”. The one major drawback of tape technology is its linearity. In other words, it takes time to position the tape to a certain point. Then it takes more time […]
July 11, 2012 – LTFS has become a buzzword in the storage community in the last couple of years. Everybody seems to be excited about it. Nevertheless, only a few have tried it out themselves, and of those even fewer can talk of success. Driven by this trend, we decided to give LTFS a go and see how we can use and integrate this technology into PresSTORE and make it easier for the not-so-knowledgeable user to employ. The only remaining tape technology that has survived over the years and proven itself through reliability and speed is LTO. Historically, even the very first […]
May 7, 2012 – The fifth generation of the LTO (Linear Tape-Open) standard is known for its embracing of LTFS (Linear Tape File System). The goal of incorporating LTFS was to broaden LTO’s range of use, increase flexibility and facilitate the exchange and transport of data. It provides users disk-like access to browsing and OS level functionality without the need for software. But while LTFS does represent a major milestone for tape-based archiving, much work still remains to be done before this technology can be considered fully developed. Tape as a storage medium has historically had its share of detractors […]
