General Data-Loss Prevention Tips

DATARECOVERYUNION.COM014 mins

data-loss The cost of a data loss event is directly related to the value of the data and the length of time that it is needed, but unavailable. Consider:

  • The cost of continuing without the data
  • The cost of recreating the data
  • The cost of notifying users in the event of a compromise

General Data-Loss Prevention Tips

Software and Hardware

  • Document your systems and archive original copies of your software in a safe place.
  • Backup your files on a regular basis, then test and verify that your backup is a complete copy of the original. External drives are an excellent choice for this task.
  • Never upgrade software or hardware without a complete, verified backup available in case you need to restore data.
  • If you are using Microsoft Windows XP, establish System Restore Points before making any significant changes to your system.
  • Write a contingency plan and practice restoring your data in case of problems. Your contingency plan should require, as a minimum:
    • Locating all available backups, including dates and types of backup.
    • Listing and locating all original software packages, detailing updates since the original installation.
    • Locating and making ready an alternate computer.
  • Deploy firewalls and virus protection.
  • Delete unused files and applications. Use a disc defragmenter, which is a program that is usually part of the operating system utilities.

Environment

  1. Ensure proper environmental conditions (stable temperature, humidity and cleanliness) and proper handling to avoid static discharge and accidental dropping.
  2. Physically secure systems from intruders.
  3. Prepare for physical disasters, including use of off-site storage for backup.

The following sections describe types of data recovery and supported formats and manufacturers. RAID data recovery, digital photo recovery, and VMWare workstation data loss are covered in separate articles under “Related Links.”

Laptop Data Recovery

As they are often carried about and exposed to different environmental factors such as heat, water and dust, laptop and notebook computers are far more likely to experience data loss than their office desktop counterparts. Their portability makes these sophisticated and essential in-the-field devices prime candidates for data loss.

Mechanical and electrical failure, software corruption and human error all play a role in data loss. Here are some of the most often noted data loss symptoms and data accessibility problems:

  • Dropped notebook – no longer turns on
  • Inaccessible drives and partitions
  • Applications that are unable to run or load data
  • Corrupted data
  • Virus attacks
  • Hard disk component failure
  • Hard disk crashes
  • Damage due to fire or liquids
  • Media surface contamination and damage
  • Accidental reformatting of partitions
  • Accidental deletion of data

Laptop Disk Drives Supported
You may not know this, but the hard disk drive embedded in your laptop is not necessarily by the same manufacturer as the laptop. Seagate Recovery Services recovers data from all notebook and laptop brands, models and interfaces – that is, from all types of hard disk drives from all manufacturers including Western Digital, Seagate, Toshiba, Fujitsu, Hitachi and Samsung.

Database Recovery

Mission-critical data is often stored in SQL Server, Oracle, Sybase, Exchange Server, Access and other databases that are maintained on networked fileservers. Relational and object-oriented database management technologies are fundamental to modern IT systems, often underpinning the lifeblood applications run by the entire corporation.

Individual media in database servers suffer from the same failure points as disk drives in personal computers and workstations. Experienced system administrators and database administrators know that a relational or object-oriented database environment is fragile unless supported by a comprehensive and well-tested backup plan.

Unfortunately, it is all too common for devices to become corrupt beyond the scope of routine recovery methods:

  • Backup files not recognizable by database engine
  • Database locked as ‘suspect’ preventing access
  • Deleted or dropped tables
  • Accidentally deleted records
  • Corrupted database files and devices
  • Damaged individual data pages
  • Accidentally overwritten database files and devices

Seagate Recovery Services specializes in making inaccessible data accessible again, recovering data from the most complex database configurations.

Database Types Supported

  • Microsoft SQL Server 6.5, 7.0, 2000, 2005, 2008
  • Oracle Lite, 8.x & 9.x, 10x, 11x
  • Sybase SQL Server
  • Sybase SQL Anywhere
  • Interbase
  • MySQL
  • PostgreSQL Standard Databases
  • Microsoft Access

SRS can also make inaccessible data accessible again for all xbase products such as dBase, FoxPro Productivity Applications Microsoft Office (including all versions of Word, Excel and Powerpoint Mail Server and Client Applications), Microsoft Exchange and Outlook Applications, and email systems conforming to the UNIX mbox format, such as Eudora and Netscape.

Server Data Recovery

Fileservers, application servers, mail servers, web servers, NAS devices and custom-built servers form the backbone of corporations’ business records storage systems. Windows servers–the most popular operating systems for servers today–along with Apple OSX, Solaris, HPUX, IAX, and Linux servers, form a significant portion of servers in businesses.

Naturally, the individual media in servers suffer from the same failure points as do drives in personal computers and workstations. However, the increased complexity of many server operating systems results in additional data loss situations:

  • Server registry configuration lost
  • Intermittent drive failure resulting in configuration corruption
  • Multiple drive failure
  • Accidental replacement of media components

Because servers are often utilized for mission-critical operations, customers need to get their data back quickly and securely. SRS services includes options for on-site data recovery, critical 24/7 options, as well as remote data recovery and special options.

Operating Systems and Platforms Supported

Tape Data Recovery

Server and personal-computer tape backup systems utilizing mm DAT, Travan, Exabyte 8mm, LTO and the various QIC formats are popular and necessary to safeguard your data. However, when these tapes fail, the situation is normally catastrophic, as these tapes were often the only remaining repository of the data. Quite often customers may no longer posses original tape hardware or software to restore from legacy environments.

Fire, smoke, water and even dropping the tape cartridge may damage the media, resulting in data loss. Internal mechanism failure and exposure to extreme temperatures, as well as logical read/write errors on a tape’s file may also result in data loss. Due to the nature of the tape solution, they are designed to withstand time to store archives. Some media if stored incorrectly or stored longer than the life span of the media may degrade causing data loss.

Here are some typical causes of tape failure:

  • Tape drive failure has corrupted tape headers
  • Tape media stretched or snapped
  • Fire & water damage Media surface contamination and damage
  • Accidental reformatting or erasure of tape
  • Accidental overwriting of headers
  • Tape backup software corruption
  • Media degradation due to the age or improper storage
  • Legacy tapes where tape drive or software no longer available

Reasons and Costs of Data Loss

DATARECOVERYUNION.COM03 mins

Computer data may be one of your company’s most valuable and vulnerable assets. According to our experience, the primary threats to your data include:

  • Hardware or System Problems
  • Human Error
  • Software Corruption or Program Problems
  • Computer Viruses
  • Natural Disasters

These five major threats to your computer data share two things in common: they are unpredictable and, in many cases, uncontrollable. Therefore, the precautions taken by IT professionals to safeguard company data cannot always prevent a data loss.

Computer users and many experts often consider lost data permanently destroyed, with no hope of recovery. Information about lost data can be complex, inconsistent or inaccurate, so it’s not surprising that data loss and data recovery are some of the most confusing and misunderstood concepts.

In addition to being a vulnerable asset, computer data is also a valuable asset.

Based on the information below it is easy to see how significant the costs of lost or inaccessible data can be. The following is a summary of the average hourly impact of lost data on a selection of different businesses.

Type of Business & Average Hourly Impact

Costs Of Data Loss

When time is crucial and data is mission-critical, data recovery may be the most practical option available. Data recovery professionals recover data from the damaged media itself, providing several advantages over alternative methods of data retrieval.

1) Complete – Data recovery professionals can safely enter the system or media to achieve a comprehensive data recovery.

2) Current – Although many people revert to backups following a data loss, those backups typically contain outdated information or could be corrupt themselves. Data recovery can help you access the most recent version of the lost data.

3) Fast – Every second that passes following a data disaster means time and money lost to your company. Data recovery reduces this downtime by quickly recovering and returning your data.

4) Cost-effective – The expense in time, money, and effort of rebuilding or re-keying lost data can be overwhelming to your company. Data recovery can provide the quickest and most complete data recovery possible.
