Academic institutions across North America, including K-12 school districts, colleges and universities, are turning to disk-based backup for data protection solutions to safeguard student records, course materials, electronic mailboxes, web applications, and other school information systems from the possibility of data loss.
Academic environments often have remote campuses, a diverse collection of servers and software applications, limited technical support staff for archiving backup media, and high expectations that student and staff files be recoverable at a moment’s notice. Disk-to-disk-to-disk network backup and recovery technologies meet these challenges head-on and provide an ideal solution for the education market.
A compelling alternative to the cumbersome and unreliable paradigm of tape backup, disk backups provides academic technology administrators with intuitive, high performance and trusted technology. Gone are the days of rotating and re-cataloging tape to find and restore files. Disk based technologies liberate IT staff with ultra-reliable automated disk-back appliances that significantly reduce administrative overhead, software licensing cost, and recovery hassles. Typical setup time is less than one hour and no per-client software license fees are assessed. Traditional tape backup devices can now be replaced with high speed, hot swappable Serial ATA hard disks that can be easily removed and stored off-site for complete disaster recovery measures.

Businesses of every size are experiencing an explosion of data storage needs – due primarily to increased governmental regulation, burgeoning e-mail and collaborative messaging, and the digitization of virtually all business information. Such developments present significant challenges for organizations – particularly the small to medium-sized business (SMB/SME) when it comes to protecting critical data through conventional server backup and recovery solutions.
SMB/SMEs aren’t keeping pace with the accelerating growth of data and the associated need to protect it. They struggle to find a complete data protection solution that is effective, reliable, affordable, and easy to use. Most data backup solutions require the piecemeal process of finding and selecting multiple vendors for the various components needed for data storage, backup, recovery, and archiving. This includes the evaluation of various offerings in servers, disk drives, tape drives, backup software – and then a systems integrator to pull it all together.
In the end, SMB/SMEs too often settle for patchwork solutions which have a high probability of failure due to incompatible components and unreliable technology (tape backup).

According to industry experts, most small to medium-sized businesses (SMBs) operate with woefully inadequate data storage protection solutions to guard against disaster. Data backup Research conducted by the U.S. Small Business Administration confirms that 93% of companies that lose their critical data go out of business within 2 years.
SMB/SMEs continually put themselves at great risk – largely because most data protection solutions are designed for the enterprise organization, and enterprise solutions are cost-prohibitive and therefore out of reach for the SMB/SME. Other solutions available to SMB/SMEs are antiquated, unreliable, difficult to use, or simply do not meet acceptable levels of performance.

Data Archiving
Comments (0)
While small to medium-sized businesses (SMB/SME) face escalating data storage and archiving demands, it’s important to recognize there is far more involved with safely and securely archiving an organization’s critical data than deploying standard server backup and recovery methods using conventional disc archiving technology.
Achieving sound and secure archive operations today requires advanced technologies that provide system intelligence concerning backup specifications, policies and history. This includes secure offsite storage, immediate access to file-level data, file-version control, hierarchical storage management, audit trails and priority-based protection. Standard backup and recovery offerings fall well short when it comes to meeting such needs.

Disk to Disk technology
The backup and disaster recovery industry today is experiencing a renaissance with the advent of Disk to Disk backup technology. The arrival of Disk to Disk based backup technology has enabled a complete rethinking of the backup process and has provided the foundation for new and exciting features to make an administrator’s life much easier.
One bright example of this renaissance is the arrival of Data Deduplication technology. Deduplication is getting a lot of press and attention lately and rightly so as deduplication is one of the biggest industry changing features to date.
Benefits of Data Deduplication
In a nutshell, data deduplication is the process of identifying duplicate copies of data, recording where that data is stored, and finally storing a single copy of that data. This process can result in large space and cost savings for customers.
The typical space savings depends a lot on the data that the data deduplication agent is processing. For example, large encrypted files with little duplicate data will not benefit much from the data deduplication process. However, a team of developers working on the same code, or a team of graphic designers working on the same project generally will have a lot of duplicate data.
A process such as Backup and Archiving which generally has a lot of redundant data (how many copies of Windows or Microsoft Office does your organization have?) can benefit immensely from data deduplication. Some vendors claim up to a factor of 300x for space savings, but a factor of 20x is more realistic.
As mentioned earlier, the data deduplication is a new feature and technology born from the paradigm switch from using tape as a backup medium to using disk as a backup medium. Unlike disk, tape is a sequential or non random-access medium; data can only be read or written in sequence.
This sequential characteristic of tape means that generally, it takes longer to access specific files. Disk to Disk backup enables immediate access to specific files without having to read through the preceding files on the disk. This greatly speeds up the process of both backup and recovery and can save valuable time. It also enables the system to be more efficient, backup the data and move on to the next task.
Client Side Deduplication
In this scenario, the agent residing on the client handles the deduplication process. The client is the ultimate authority of what data resides on it, and what data is changed. Especially for remote offices where network bandwidth is at a premium, being able to deduplicate the data prior to sending it to the backup appliance at the main office saves valuable bandwidth. The down side to this is that the processing of the data consumes client processor time. Depending on the circumstances, the trade off for network bandwidth could be well worth it.
In-Band Deduplication
For appliance based products that use the in-band approach, data is deduped before the data is actually written to the disk. This process has the advantage that the data is only touched once. However, the in-band approach adds increased overhead to the actual backup process, and can slow down the process, which is not ideal.
Out-of-Band Deduplication
For appliance based products that use the out-of-band approach, backup data is first written to disk in-line during the backup process. After the backup is finished, the data is then processed and duplicated data is discarded. Since the data is not processed in-line, there is no overhead penalty during the backup. The trade-off here is that extra storage is necessary while the backup data is being post processed, but there is the assurance that the backup data is captured as quickly as possible.
Best Approach
In our view, the biggest advantage of disk-to-disk technology and data deduplication is being able to combine all three approaches to leverage the strengths of each, while mitigating their weaknesses. For example, Continuous Data Protection (CDP) is a Client Side Approach that makes a lot of sense. A CDP based client knows which data has been modified, and can keep track of it on the fly. Newly modified data is rarely a duplicate and can be confidently sent to the backup server appliance. When the back end server is coordinated with smart clients, duplicated data can be identified on the fly; greatly reducing overall network congestion while minimizing client side processing.
Data deduplication is big win in any backup environment; as is replacing tape with disks as an archival medium. We recommend you consider incorporating Disk to Disk and Data Deduplication technologies into your Backup processes.

Disk Backup
Comments (0)
The uncertainty of today’s technology requires a disk backup solution that can best serve your business in efficiency and convenience. Managing your solution requires understanding of your recovery point objective, recovery time objective, and data security. Recovery point objective is essentially the recorded data restore point that your system will be reverted to in the event of a loss. This recovery point needs to be constantly updated in order to store your most recent file changes. The recovery time objective is the amount of time between the loss and recovery of data. A longer recovery time objective means you won’t have access to these files for that amount of time. Most important in your disk backup solution is your data security. Backing up your files is not advantageous if it exposes them to unauthorized access. Data encryption and other security features should be implemented to protect your information with each backup performed.

Data Backup

Backing up data and creating important restore points for your business’ stored network and computer information requires the use of top-level backup appliances. Using several components to build personalized backup appliances is a viable option for data systems today. Backup services will typically use a processor, Ethernet power supplies, SATA drives, and RAID technology. These systems are more reliable than tape-based archives, as disk-based technology records an actual copy of file data versus simply archiving the information linearly. The Serial Advanced Technology Attachment (SATA) provides for transfer of data between the computer or network and storage disks. A Redundant Array of Inexpensive Disks (RAID) is used to describe the actual storage mechanism. Data may be stored in two or more hard disk drives. This technology offers faster and more reliable data storage, and the use of multiple hard disk drives offers a greater volume of data capacity as well.

Tape Backup
Comments (0)
Tape backup systems surfaced as popular options for personal computer and business use in the mid 1970s. The technology, innovative at the time, used magnetic tape reels to backup important information contained within a home or business computer for restoration needs in the event of a computer failure. Recording methods for tape backup systems may be linear or scanning. Linear recording stores information copied in parallel tracks. Many cassettes may record simultaneously using this simple form of recording, yet the amount of data allowed to be recorded is limited with this method. Linear serpentine recording allows for much higher data amounts than traditional linear methods. Scanning technology allows for data to be recorded across the width of the tape versus the length. Specific types of scanning include transverse scans, arcuate scans, and helical scans. Although still in use, modern backup systems typically use a disk solution versus the older tape recording methods.

Disk Backup

Disk backup solutions have become the most popular way for businesses to ensure important data is available for restoration in the case of a network failure. Current disk backup solutions employ technology involving several different schedules for information backup. Some systems are programmed to store new files and information on continuous data protection, where data is backed up whenever a change is noted in any file. Full backups perform an entire scan of the system, and can be scheduled in increments or at regular time intervals. Unstructured backups are the most unreliable and inefficient, as they require a physical backup performed by the user whenever deemed necessary. Disk backup provides the security of saving important data and changes to files in the event a disaster recovery is needed, or files are accidentally deleted. Disk backup solutions offered by Revinetix provide small to medium businesses the exceptional convenience of a one-stop shop with easy to use software and dedicated IT help.
