Why the Complexity of Data Backup and Recovery is Not to be Underestimated

Trends in the world of data is causing the backup and recovery of that data to be more complex than it has ver been in the past. The increased complexity of data backup and recovery should not be underestimated.

According to the IBM IEEE Spectrum IBM Bets $3 Billion on the Internet of Things “IBM’s latest business move anticipates huge growth in the Internet of Things, the growing swarm of devices capable of collecting data and sharing it all online. That swarm could include wearable wristband devices such as the Apple Watch, exercise and health-monitoring devices, household gadgets such as Nest’s smart thermostat, and smart cars capable of sharing information about weather and traffic conditions. IBM is betting that many companies will pay handsomely for help in analyzing the deluge of data coming from thousands or millions of sensors and computing devices.”Backup Data Center

The reason data is becoming more complex is because what we consider to be data today we never considered before. What is data? Data is an entity that is input to analysis and reporting so that we may act accordingly. If we need input to determine an action, then the input is data. There was a time when corporations needed only numbers and words for data – for financial reporting for instance. Now, corporations need analog information from devices, sentiment from social media and geo-spatial input to determine the location of the event at the time of interest.

If it is data it needs to backed up for the potential of being recovered upon request. This is becoming more complex than ever.

Data and the backup of that data is getting more complex while over worked IT staffs are still assigning backup and recovery to the ‘new guy’ or sometimes to the most junior specialist in staff. As we have discussed in this blog before “IT staffs are overloaded with mission critical day-today activities. It is understandable that Data Backup may be assigned to the newest member of the team and not deeply analyzed. However, it will become the most critical task the IT staff will undertake when that data needs to be recovered.”

Outsourcing Data backup processes to experienced professionals that specialize in this new form of data is a logical first choice to consider. One purpose to outsource is to free up the time of the IT staff to focus on core business strategies instead of training on the new Backup and Recovery techniques and then spending hours each day looking at logs and emails. The Storage Administrator can be released from the endless cycle of repeating the same tasks over and over again. And, the processes can be designed and performed by experts in the field of complex data backup and recovery.

Develop Backup and Recovery Policy Management to Support GRC

Back up and restore policy management is a critical piece to your GRC (Governance, Risk, Compliance). Policy management encompasses all the rules for where data is stored, how many versions can be stored, and for how long it is stored.

Compliance and Regulation words puzzle piece,business conceptConsider that data is not only to be backed up for protection of a catastrophic event, but, it also needs to be restored for many different purposes and meet varying requirements. This requires  Data Backup strategies must be planned and policies developed to assure all company requirements regarding data retention and recovery are met, such as;

  • Regulatory Requirements
  • Data Breaches
  • Court Orders

Tivoli Storage Manager (TSM) provides backup and restore policy management. Policies in TSM are rules that determine how data is stored and managed. The rules include where the data is initially stored, how many backup versions are kept, how long archive copies are kept, and so on. You can have multiple policies and assign the various policies as needed, or even to specific files. Policies Assign a location in server storage where data is initially stored.

Server storage is divided into storage pools that are groups of storage volumes. Server storage can include hard disk, optical, and tape volumes.

Clients use Tivoli Storage Manager to store data for any of the following purposes:

  •  Backup and restore: The backup process copies data from client systems to server storage to ensure against loss of data that is regularly changed. A policy includes the number of versions and the retention time for those versions. The server retains versions of a file according to this policy, and replaces older versions of the file with newer versions.
  • Archive and retrieve: The archive process copies data from client systems to server storage for long-term storage. The process can optionally delete the archived files from the client systems. The server retains archive copies according to the policy for archive retention time. A client can retrieve an archived copy of a file.
  • Backup set recovery: Backup set recovery is the creation of a complete set of backed-up files for a client. The set of files is called a backup set. A backup set is created on the server from the most recently backed-up files that are already stored in server storage for the client. The policy for the backup set consists of the retention time that you choose when you create the backup set. You can copy a backup set onto compatible portable media, which can then be taken directly to the client for rapid recovery without the use of a network and without having to communicate with the Tivoli Storage Manager server.
  • Migration and recall Migration: is a function of the Tivoli Storage Manager for Space Management (for supported UNIX and Linux systems) and Tivoli Storage Manager HSM for Windows programs. It frees client storage space by copying files from client systems to server storage. On the client, the program replaces the original file with a stub file that points to the migrated file in server storage. Files are recalled to the client systems when needed. The process of migrating and retrieving data through these programs is transparent to users and applications, other than a possible degradation in performance as compared to data stored on locally attached, tier one disk. Policy determines when files are considered for automatic migration. On the UNIX or Linux systems that support the Tivoli Storage Manager for Space Management program, policies determine whether files must be backed up to the server before being migrated. Space management is also integrated with backup. If the file to be backed up is already migrated to server storage, the file is backed up from there.

API’s Are Being Developed to Keep Up With the Expansion of the Internet of Things

When referencing the Internet of Things, it is important to understand that it is really about the data being transmitted, not the devices or the applications. If these devices or applications remained in communication with only their own platform, they would not be part of IoT. These devices must be interacting with traditional applications to be playing a part in the IOT.

To facilitate the expansion of the IOT, APIs are being built at an accelerated pace.network security

In the report from GIGAOM Research called Building an API-driven Ecosystem for the Internet of Things, there are Key findings that include:

  • IoT hardware is not the end game: The profits, margins, and innovations will come from the new products and services built on open, flexible APIs.
  • Technical excellence is not enough. Successful IoT developers must properly onboard, support, monetize, secure, and evolve their platforms in order to compete.
  • Modern APIs enable service composition rather than individual functions, creating an IoT supply chain.
  • Ecosystem architects should build on practices established in mobile-app development for their foundation, customizing only when necessary.

The IT staffs of medium-sized companies will be seeing more requests to integrate the IoT with their mission critical applications. There is a need for the data from these devices and applications to be made available to business applications for increased corporate value. Businesses are integrating specialized devices and applications with core business processes for analytics and advanced business processing. This data has now become corporate data.

The result is more complex data types within the corporate business data environment. This provides an additional burden on the IT staff in understanding the implications of developing backup procedures for these diverse data types.
