Digital Data Storage (DDS) is a computer data storage technology that is based upon the Digital Audio Tape (DAT) format that was developed during the 1980s. DDS is primarily intended for use as off-line storage, especially for generating backup copies of working data. Backups delivered as offsite/cloud-based storage with disks only or using disk-to-tapes methodology. Further, Digital Edge can play a critical role in your Backup, Disaster Recovery, and Business Continuity Plan by verifying and validating backups for regularly scheduled compliance reporting.

Although it may be tedious and time-consuming, the 'Backup' process is a crucial and integral part of any enterprise. Typical Backup issues/challenges are…

• Jobs failures;
• Free space runs out;
• Tapes need to be rotated and sent offsite;
• And most importantly, backups have to be verified and validated as often as possible.

Digital Edge provides services that go beyond software and storage. We work with our clients to develop policies, implement them, validate the implementation and regularly test the data. These are the questions we ask in order to develop a backup strategy that meets your Business Continuity Plan's goals and objectives…

• Do you have a fully defined Business Continuity Plan (BCP), including RPOs and RTOs?
• Did you include monitoring and verification procedures?
• What is your protocol and frequency for testing?
• What is your approach for analyzing and optimizing your solution?
• Have you considered Cloud Backup Service, Cloud Storage Service, and Disaster Recovery as a Service (DRaaS)?

To ensure the process runs effectively, we execute frequently scheduled Standard Operating Procedures (SOP) that test the functionality of the overall solution. We continually optimize our Backup technology to guarantee our clients do not waste their capacities and resources. For example, databases have their own highly efficient mechanisms for backup which we use to preserve transactional data integrity and deliver fast recovery.

Digital Edge will deliver a complete and robust Business Continuity Solution by documenting your business requirements, including RPOs and RTOs, providing comprehensive design, implementing 24/7 monitoring, and verification. In addition, we can play a critical role in your Backup, Disaster Recovery and Business Continuity Plan by verifying and validating scheduled backups for compliance reporting.

These are the top 5 questions to consider when looking for a potential provider and our answers:

1. On encryption keys: Assuming that my file data is encrypted on your storage, who has access to the encryption keys?We use self-encrypting disks from Fujitsu. If you have access to the server – you can see the data. If someone just takes the disks – the data will not be readable.

1. On tech support access to data files: Does tech support -- employees, contractors or third parties -- have access to the files I store on your cloud service?Access to the server is controlled by the client. Access is granted to our support technicians per client needs.

1. On keyword scanning: Do you or any third party scan or otherwise process my data files? If so, what is done with the information obtained during the scan?No.

1. On copies of data files: To provide a secure, redundant service, is it safe to assume that you back up or replicate my data files to another location or system?If so, what controls are in place to keep internal staff or third parties from accessing those copies of my data files?Backups are done on the whole VM level. It can be restored but to access data you would still need access to the server. Backups are stored on systems belonging to Digital Edge and not sent outside of our datacenter. Employment agreements and policies prohibit accessing client's data without a request ticket from the client. We operate under ISO 27001 for data security.

1. On audits: How do you audit your own internal policies with respect to unauthorized internal access to customer data files?Once a year we run internal audit and then ISO audit based on ISO 27001 standard.

Digital Data Storage (DDS) is a computerdata storage technology that is based upon the Digital Audio Tape (DAT) format that was developed during the 1980s. DDS is primarily intended for use as off-line storage, especially for generating backup copies of working data.

A DDS cartridge uses tape with a width of 3.81mm, with the exception of the latest formats, DAT-160 and DAT-320, both which use 8mm wide tape. Initially, the tape was 60 meters (197 feet) or 90 meters (295 ft.) in length. Advancements in materials technology have allowed the length to be increased significantly in successive versions. A DDS tape drive uses helical scan recording, the same process used by a video cassette recorder (VCR).

Backward compatibility between newer drives and older cartridges is not assured; the compatibility matrices provided by manufacturers will need to be consulted.^[1] Typically drives can read and write tapes in the prior generation format, with most (but not all) also able to read and write tapes from two generations prior. Notice in HP's article that newer tape standards do not simply consist of longer tapes; with DDS-2, for example, the track was narrower than with DDS-1.

At one time, DDS competed against the Linear Tape-Open (LTO), Advanced Intelligent Tape (AIT), VXA, and Travan formats. However, AIT, Travan and VXA are no longer mainstream, and the capacity of LTO has far exceeded that of the most recent DDS standard, DDS-320.

Generations[edit]

DDS-1[edit]

Stores up to 1.3 GB uncompressed (2.6 GB compressed) on a 60 m cartridge or 2 GB uncompressed (4 GB compressed) on a 90 m cartridge.

The DDS-1 cartridge often does not have the -1 designation, as initially it was the only format, though cartridges produced since the introduction of DDS-2 may carry a -1 designation to distinguish the format from newer formats. A media recognition system was introduced with DDS-2 drives and cartridges to detect the medium type and prevent the loading of an improper medium. From 1993, DDS-1 tapes included the media recognition system marks on the leader tape—a feature indicated by the presence of four vertical bars after the DDS logo.

DDS-2[edit]

Stores up to 4 GB uncompressed (8 GB compressed) on a 120 m cartridge.

DDS-3[edit]

Stores up to 12 GB uncompressed (24 GB compressed) on a 125 m cartridge. DDS-3 uses PRML (Partial Response Maximum Likelihood) to minimize electronic noise for a cleaner data recording.

DDS-4[edit]

DDS-4 stores up to 20 GB uncompressed (40 GB compressed) on a 150 m cartridge. This format is also called DAT 40.

DAT 72[edit]

DAT 72 stores up to 36 GB uncompressed (72 GB compressed) on a 170 m cartridge. The DAT 72 standard was developed by HP and Certance. It has the same form-factor as DDS-3 and -4 and is sometimes referred to as DDS-5.

DAT 160[edit]

DAT 160 was launched in June 2007 by HP, stores up to 80 GB uncompressed (160 GB compressed). A major change from the previous generations is the width of the tape. DAT 160 uses 8 mm wide tape in a slightly thicker cartridge while all prior versions use 3.81 mm wide tape. Despite the difference in tape widths, DAT 160 drives can load DAT-72 and DAT-40 (DDS-4) cartridges. Native capacity is 80 GB and native transfer rate was raised to 6.9 MB/s, mostly due to prolonging head/tape contact to 180° (compared to 90° previously).^[3] Fnaf one layout. Launch interfaces were Parallel SCSI and USB, with SAS interface released later.

DAT 320[edit]

In November 2009 HP announced the DAT-320 standard, which stores up to 160 GB uncompressed (marketed as 320 GB assuming 2:1 compression) per cartridge. Native transfer rate was raised to 12 MB/s.

The next format, Gen 8, was canceled.
