Disk Data Recovery Services

Data backup and archiving can be a waking nightmare, how best to balance the demands for instant access against the equally important need for security and reliance? Loss of data is one of those events that can quickly turn the IT Professional's life from one where they receive plaudits for how well the systems are running to one where their whole career might be under threat.

What is the best system to use? Are disk based easy access systems a better option than tapes and tape libraries, or are the more traditional data backup and data recovery methods a better bet for long term data security? Each technology has its exponents and its detractors. Tape is seen by many as slow and inflexible whereas disk based systems give a convenient, easy to operate, backup system with the ability to add on extra features such as de-duplication that require a dynamic filing system.

Add to this the current cost of hard disks, a 1.5TB disk does not cost that much more than a 1.6TB LTO 4 tape, and the tape capacity is based upon average data compressibility, the native capacity is 800GB, and disk is not the expensive cousin any longer. So does this mean that tape is going the way of the Dodo and that the future is disk based? The question to ask is "what is the purpose of our backup system".

Is it convenience?

A system that is easy to use and to manage is operationally a better bet than one that is cumbersome or complicated. It also means that data does get backed up, even the most robust method falls apart if no one uses it. So if you have users with laptops who can quickly kick off a backup via the internet with no real effort, then it will happen and you are significantly less likely to find your self at the mercy of a data recovery company.

Is it manageable?

The downside to ease of use is overuse and abuse. Make life too easy for people and they will back everything up without any thought and you end up with a nightmare. Get the policies right though and all should be well. With a dynamic filing system you can implement de-duplication and single instance-storage so that the actual space requirement is minimised.

Does it provide business continuity?

Again, in most instances the disk-based system can win over the other options, data is effectively on-line, or at least near-line. The act of restoring data following an accidental deletion of a corruption is not too arduous, and should not involve several days nagging the IT department before the data is back in place.

So, get rid of the tape storage?

Not so fast. The on-line backup, and the clever sophisticated disk based store might give you convenience and an immediate result when there are minor problems but what if the problems are more severe or the requirement for data is external, for example related to banking regulation or some other aspect of compliance?

Disaster Recovery

The overhead of getting the tapes, cataloguing them and restoring the required data, seems less of an ordeal when there is a total system failure or a wipeout, for example following a fire or a flood. The fact that you can send for the backup tapes from off-site storage and get up and running again is all that matters. Even when the on-site backup tapes have been submerged under a few feet of water, the chances of a full data recovery are good, far better than those for any disk, especially one that was still spinning when the flood came.

Where issues of regulatory compliance arise being able to take a set of tapes that provide a snapshot of the systems at the required point of time is a major boon. No question that the live data may have been tampered with, or that a snapshot from the near-line system may have been inadvertently deleted, the month end tapes for the required time will have been sitting keeping a copy of the data nice and secure, and with a lower power requirement than an always-on system. If you have taken the chance to use the WORM feature of some of the tape systems such as LTO or T10000 then this confidence can be enhanced further.

Data Recovery from Tapes and Disks

Record some data to a tape and then to a hard disk drive. Take each and drop them from six foot of the ground, then try recovering the data. The disk might work if you are very lucky, the tape will almost certainly work. At worst the tape casing will required a bit of work to but generally it will be fine. As a data recovery specialist I know which I would rather have my backup archive stored on in the event of an impact, it would be the tape every time.

The point is that the two data storage media are different, and designed for differing purposes. Disk based systems give convenience, fast response and can be an invaluable near-line backup system that will smooth out the delays that could otherwise be caused by minor operating glitches. Tape based systems, however, give a solid backstop of data security and a reliable data audit trail.

The answer to "tape or disk?" is ideally "both". The rather cumbersomely named D2D2T (disk-to-disk-to-tape) systems provide a hybrid of both technologies making use of the speed and flexibility of disk for immediate backup and recovery, but with the robust backing of tape storage to add that extra level of security.

On August 24, 1992 hurricane Andrew landed in Homestead, Florida laying a path of destruction as it moved through the state. This was the worst storm to hit the area in over 30 years, and many of the people living in the area were new to the region and never had experienced a storm like this before.

The Category four hurricane hit with winds gusting to speeds of 175 miles per hour, and swells reaching 17 feet in height along the coast. The storm destroyed property and left as many as 250,000 people homeless. Sixty Five people died as a result of the storm, and many more suffered injuries.

The damage left in the wake of the hurricane was devastating. The ferocious storm destroyed or damaged an estimated 600,000 homes and businesses. Water and wind damage were in evidence all over. A great many of the homes located in this area were small mobile homes, and virtually all of them where reduced to rubble. Local roads and highways received damage, and all major utilities experienced major interruptions of service. Local residents of the area were, in some cases, without power, water or, sewage for as much as six months. The Florida coast was also home to many boats and water craft and insurance claims for damage to these craft amounted to millions.

The social impact of this storm was far-reaching. Many families left the area to rebuild their lives in safer and less volatile locations. A huge effort was made by local authorities and emergency service agencies to provide better methods and technology for the detection, and tracking of such storms. The one good thing that happened as a result of this storm was that it motivated the locals to better prepare themselves for the future.

The economic consequences of this hurricane were felt far and wide. After the storm almost one and a half million people where left without power, some for as long as 6 months. Businesses could not operate or had to move to temporary facilities in an effort to rebuild and recover lost revenues. Many businesses lost financial records, and data that were crucial to the company's operations. The total damage from the storm was estimated at approximately 26 billion dollars.

The residents of the state of Florida where ill prepared for a hurricane of this magnitude. Many were of a generation that had never before experienced such devastation, since the last major storm to hit the area occurred some 30 years before. The need to take precautions in an effort to limit the effects of a natural disaster is essential. Many insurance companies now offer discounted rates to companies that include disaster planning into their standard business plans. It is not possible to be too well prepared.

You can never be too prepared when disaster strikes. Protect yourself from data loss with online backup from Global Data Vault. Avoid downtime, revenue loss and angry customers with remote backup services from Global Data Vault.

SCO UnixWare operating system is a Unix-based operating system that is primarily known for its reliability, stability and scalability. While the operating system is safe and reliable, it can also be corrupted and unmountable due to super block damage or corruption, inode corruption, boot errors, VTOC (Volume Tables of Contents) damage, OLT (Object Location Table) damage and malicious software like virus. In most cases of operating system corruption, you encounter an error message. Once you encounter the error message, the data stored in the hard drive becomes inaccessible. To overcome such situations, the best possible way is to restore the data from an up-to-date backup. However, in case of no backup availability or backup failing short of restoring the required data, you need to use advanced SCO UnixWare Data Recovery Software.

Consider a practical scenario, where you encounter the below error message when you attempt to boot your UNIX based operating system:

"Mar 15 17:26:21 ioccrmprep1 unix: WARNING: msgcnt 31 vxfs: mesg 017:
vx_ilock - /opt/data/ora16/preprod file system inode 10 marked bad"

The above error message indicates that inode 10 has been marked bad. Data saved in the hard drive becomes inaccessible after the above error message appears.

Cause:

The root cause for the occurrence of the above error message is VERITAS File inode corruption as a result of transient fiber link failures.

Resolution:

To resolve the above error message and access the data, you need to take these steps:

1. Unmount the file in order to attempt repairs on corrupted inodes. Use the command to analyze the superblock on the failing file system:
% echo "8192B.p S" | fsdb -F vxfs /dev/vx/rdsk/rootdg/meta
2. Run a full fsck with the -n option to see which inodes are marked bad
3. Set the "aflag" field to 0x0 using fsdb. This step must be done very carefully since it involves writing to the file structure itself. The incorrect use of fsdb can destroy the file system.
4. The inode aflag has been cleared for the 3 inodes. Verify it with fsck.
5. Now it should be safe to run a full fsck with the -y option
6. Mount the file system and check the inodes

If the above steps fail to resolve the issue, you need to reinstall the file system. These file systems act as pointers to the files and folders saved on the hard drive. Reinstalling the file system will erase all those entries and your data will become inaccessible. In such circumstances, you need to go for an advanced SCO UnixWare Data Recovery Software. Such SCO UnixWare Data Recovery tools use advanced scanning algorithms to recover your lost data.

Stellar Phoenix (SCO UnixWare) Data Recovery is powerful SCO UnixWare Data Recovery utility. It is compatible with VxFS [Veritas - VxFS1, VxFS2 & VxFS4] and UFS. It gets installed on Windows (XP, 2003, 2000, NT, ME, 98 and 95) and the affected SCO hard drive should be connected as slave.

The database may be corrupted. The Microsoft Exchange Transport service is shutting down. Manual database recovery or repair may be required."

After the above error, Microsoft Server does not let you access your database. At this point, you have to verify the cause of this problem and perform EDB File Recovery by resolving it.

Cause:

The error message below indicates that specified ESE (Extensible Storage Engine) database is damaged. It is preventing MS Exchange database services from starting.

- ESE, also called JET Blue, is an ISAM (Indexed Sequential Access Method) data storage technology intended by Microsoft. The ESE is particularly used as a key component of the Microsoft Exchange Server and the Active Directory.

How to Fix ESE Corruption:

You can carry out following things to sort out this issue-

1. Delete the defined database and corresponding transaction logs. You must not remove the database if you have significant data in the database.

2. Repair the damaged database using Isinteg.exe tool or restore it from backup.

However, if none of the above methods helps you to work around the problem, EDB Recovery Tool is the only option to go for. They carry out in-depth scan of entire EDB file using high-end scanning techniques and restore all database objects such as emails, notes, contacts, tasks, and more.
