Tape vs Cloud for Archive and Cold Data

Post by Joseph Ortiz (thank you)

As my colleague, George Crump, discussed in a previous article, “What is Better than Cloud Storage for Cold Data”, cloud storage is great for processing active data but becomes increasingly expensive for storing cold data that is seldom accessed. While we have previously examined a few weaknesses of cloud storage such as latency and bandwidth issues, we have not really examined the actual costs of cloud storage in any detail to see the potential costs of storing large quantities of cold data and archive data long term in the cloud, or retrieving any of that archived data until now. There is a reason that many organizations are now starting to question their decision to store large quantities of cold and archive data in the cloud long term.

Buying Guide: Backup Appliances

Post by Drew Robb (thank you)

IDC recently put out a report on the worldwide purpose-built backup appliance (PBBA) market. The big news was declining revenues, which are likely to continue due to changes in the dynamics of this space.

“The worldwide PBBA market experienced a year-over-year decline in the second quarter of 2015 as the market continues to evolve,” said Liz Conner, a storage analyst at IDC. “Focus continues to shift away from hardware-centric, on-premise PBBA systems to hybrid/gateway systems. The results are greater emphasis on backup and deduplication software, the ability to tier or push data to the cloud, and the increasing commoditization of hardware, all of which require market participants to adjust product portfolios accordingly.”

SMR Drives: Are they too late to the game?

Good post by Petros Koutoupis (thank you)

The sudden popularity over NAND Flash has spelled doom for traditional magnetic Hard Disk Drives (HDD). For years we have been hearing how HDDs are reaching the end of their life. We have also heard the same about Tape drives, long before that. Although, it would seem that the prediction on HDDs may become a bit more of reality, sooner than expected.

Backup is not Archive

Good post by Joseph Ortiz (thank you)

In order to protect their data while dealing with explosive data growth, many organizations have started backing up their data to the cloud in an effort to reduce their storage and data center costs as well as obtaining data redundancy without the need to maintain a separate physical DR site. Many also mistakenly believe that these additional backup copies qualify as archive copies. Unfortunately, they do not.

LTO Program Announces Generation 7 Specifications

Post by Adam Armstrong (thank you)

Today the LTO Program Technology Provider Companies (HP, IBM, and Quantum) announced new specifications for the LTO Ultrium format generation 7 or LTO-7. The new specifications more than double the capacity per tape cartridge bring the capacity to 15TB (when compressed) up from 6.25TB of the previous generation. And the new specifications have even faster transfer speeds up to 750MB/s or 2.7TB/hour/drive, up from 400MB/s or 1.4TB/hour/drive of the previous generation.

Is a Copy a Backup?

Good post by W.Curtis Preston (thank you)

Are we breaking backup in a new way by fixing it?  That’s the thought I had while interviewing Bryce Hein from Quantum. It made me think about a blog post I wrote four years ago asking whether or not snapshots and replication could be considered a backup.  The interview is an interesting one and the blog post has a lot of good points, along with quite a bit of banter in the comments section.

FCoE is dead! (For real)

Good post by Enrico Signoretti (thank you)

How many times have you heard this statement? Tape is dead! Mainframe is dead! So on and so forth… it turned out not to be true, most of the times it was just a way to say that a newer technology was seeing a strong adoption, so strong as to eclipse the older one in the eyes of the masses. But, in the case of FCoE, it is slightly different.

Deduplicated Backup Storage – 3 Modes of Operation

Good post by Brian Seltzer (thank you)

The move away from tape backups towards disk-based backups has been going on for a while now.  Storing backups on disk generally means faster backups and faster restores.  However, disk isn’t as cheap as tape, and storing many terabytes or even petabytes of data on disk can lead to sprawling storage systems.  To reduce the cost and physical size of backup disk, backup storage is commonly deduplicated.  This can have a pretty dramatic impact on the size of backed up data, especially if your retention period include multiple full backups.

Quantum Doubles Down on Data Archiving

Post by Pedro Hernandez (thank you)

Quantum is tackling the growth of unstructured data, and its growing impact on IT budgets, with three new offerings unveiled today.

The San Jose, Calif.-based data backup specialist has taken the wraps off its new Artico NAS appliance that provides fast file services courtesy of its internal disks and while supporting data archival operations that target the company’s Lattus Object Storage hardware, Scalar tape libraries (i80, i500, i6000) or Q-Cloud Archive.

Combining snapshots and backups for best practice data protection

Post by Simon Watkins (thank you)

When it comes to best practice data protection for your business-critical applications, no single snapshot or backup technology can provide the complete solution. Snapshots and backups have different yet complementary roles to play for availability, backup and disaster recovery.

When you’re looking for a comprehensive, tiered and converged data protection architecture that balances availability and protection, it should not be a question of either-or but more a case of where and how to best use snapshots and backup.
