Your Company Needs Linux Server Backup

By blogger on

You should look into Linux server backup to protect yourself from unforeseen data loss. Data are very important especially because they are widely used in todays trade and daily life. Losing data might mean losing customers for a business. Despite the growing reliability of data over the recent years, it cannot be avoided that calamities and disasters may strike anytime putting a threat to data.

Some risk potentials are not physical. Malwares, worms, Trojans, and other viruses could be perfect examples. It is also possible to be affected by hacking activities which may cause data to be manipulated without authorization. While a stable firewall may help, only Linux server backup can maximize data security.

Linux has set the highest standards to be able for it to have the best Linux server backup solution. It has an extremely stable and strong operating system that allows hosted sites to have a very quick upload time. This flexibility allows advanced features to be available at free of cost. For major operating systems such as Ubuntu, CentOS, and Red Hat, options are web-based thus remote backup is possible to carry out anytime and anywhere.

The best thing about Linux server backup is that it offers network encryption. This makes data less prone to unauthorized access and manipulation. Majority of Linux distributions comes with 256-bit network encryption, 256-bit AES storage encryption, and unique security certificates thus your data become more secured against unlawful attacks. These features can give you the peace of mind knowing even your most delicate information are free from leakage.

Another great thing about Linux is that it is highly scalable. It can easily adapt regardless if the environment is small or large scale containing petabytes of data. Being dynamic and scalable, Linux server backup can meet anything you require from it without compromising backup quality and data integrity.

These are some of the features that you should look for in Linux server backup. The operating systems kernel has been built from the ground up to be highly robust and scalable, handling anything you can give it. It is used actively around the world in a number of small and large-scale environments without any problem. Among other things, the security that Linux server backup offers safeguards your data the best way possible against attacks and hacking.

How to Fix Unable to resolve UUID Error in Linux

By blogger on

Modern distributions of Linux operating systems use UUID (Universally Unique Identifier) to uniquely identify hard drive or other data storage devices, in place of the conventional block names like /dev/sdb and /dev/hda1. It is due to the fact that UUID is never modified, even if the hard drive is switched. It is stable as compared to traditional methods, and prevents system failure and need of Linux Data Recovery solutions.

UUID is a 128-bit string that is used for making the Linux hard disk management simple. If you look at /etc/fstab file in your Linux computer, you find the entry in the following format, in place of the familiar hard drive designation:

UUID=62fa5eac-3df4-448d-a576-916dd5b432f2

In comparison to the traditional hard drive identification techniques, UUID is quite easy and reliable. For instance, in the traditional Linux systems, when you try to insert a new hard drive in a system that already has two hard drives, the drive is inserted between existing drives. At this point, ‘mount’ command attempts to mount the newly inserted drives as home.

In such situation, you need to log on as a single user for resolving the problem. However, when you log on, it gives you some error message and in the worst case scenario, you may encounter kernel panic. You can fix this issue using UUID.

UUID creates a unique entry for each hard disk volume in the Linux file system tree. Using UUID offers easy management of your Linux hard disks and creates less complication while adding or removing the disk.

Although, UUID is quite useful and it provides various advanced features, but it also has some faults. Sometimes, you may encounter the below error message when you attempt to access a UUID based Linux hard drive:

-Fsck 1.40.8 (13-Mar-200 fsck.ext3: Unable to resolve ‘UUID=d8533154-cef1-4cce-a823-9f3f74aab65b’-

After the above error message, you can not access the particular hard drive. All the data stored on your hard drive become inaccessible and you come across critical data loss. At this point, Linux Recovery Software come for your rescue.

The applications perform absolute Data recovery linux in most of the logical data loss situations, using advanced scanning algorithms. These tools enable you to perform Linux Recovery on your own as they have self-descriptive and simple graphical user interface. With read-only and non-destructive behavior, the applications are completely safe to use.

Stellar Phoenix Linux Data Recovery is the most comprehensive application for perfect recovery of all lost data. The software is compatible with all Linux distributions including SUSE, Debian, Red Hat, and Fedora. It recovers lost data from Ext4, Ext3, Ext2, FAT32, FAT16, and FAT12 file system volumes.

Choose The Right Linux Distribution For Smart Computing

By blogger on

Linux is one of the most popular operating systems out there after the Windows family. What sets Linux distinctly apart from others is the fact that you can download it for free. Unlike Windows operating systems which come with a hefty price tag, Linux does not cost absolutely anything and Linux setup is quite easy. Even you dont need to use any virus remover as there is very little or no chance of virus infection.

For beginners, it can be quite daunting to decide which distribution would be best for them. This is because there is a plethora of Linux distributions out there from which you can choose from – Ubuntu, Red Hat, Fedora, Mandriva, Opensuse, and so on. Each distribution, or distro, has its own strengths and features unique to it.

The first and foremost concern that you should consider is your hardware. All Linux distros are not built the same. Although most Linux distros try to be as hardware friendly as possible, you might discover that some work better with your hardware than others. So the best way to decide which distro would be right for you is to try out a handful of the most popular distros and see for yourself as to which of them work the best on your hardware. You will discover that some distros will detect all your hardware and work flawlessly, while others may not even boot on your PC or laptop.

The next thing you should consider is codec availability. Some popular distros like Ubuntu and Fedora do not ship with any kind of codecs to play common files like your mp3s or high-definition videos. There are distros based on these very distros that are more usable and ship with support for all of your audio and video files. Linux Mint, based on Ubuntu, is one such distro.

Ubuntu is probably the most popular and widely used Linux operating system that there is. It is based on Debian, another huge distribution with a very loyal fan following. Ubuntu also has one of the largest communities out there and you are more likely to find help on anything related to Ubuntu than any other distro. This is one of the great advantages of using Ubuntu or anything based on it, such as Linux mint. You will find it easy to look for help online should you get stuck with anything.

Fedora, sponsored by the Linux giant red hat, is also quite popular among Linux users. Like Ubuntu, it cannot come with any codecs pre-installed due to patent issues. Not all software companies allow Linux distributions to pre-install their proprietary software. For example, Microsoft license does not allow Linux distributions to contain programs like internet explorer or windows media player codecs. Similarly, popular Linux distros like Fedora, Opensuse and Ubuntu cannot ship flash, java, and other such proprietary software. If this is a concern for you, then download distros like Linux mint or PcLinuxOS, which come with all these necessary programs pre-installed.

So if you have really decided to move on to Linux, just take the plunge and set up Linux on your PC. You will not regret the freedom and liberty that Linux comes with.

Cant Find Ext2 File System Error In Linux

By blogger on

Linux is the most popular open source operating system. You can use Linux on same system on which you are already using Windows operating system. The method is known as Dual Boot. It gives you the facility to have the features of both operating systems on same computer.

If you are working on Windows operating system and want to access data from Linux volume, you can mount the drive and can use it. In this way, you can use all of the data stored on your hard drive by using any of the operating system.

But sometimes, using Dual Boot can become problematic. When you try to access Linux volumes, by mounting them, you can fail to do it and can get some sort of error messages. The common error messages are:

“can’t find ext2 File System on dev ide1 (22, 65)”

Or

“mount: wrong file system type, bad option, bad superblock, or too many mounted file systems”

After these error messages, you can’t use the Linux partitions. And when you boot your system using Linux operting system, the system just can’t boot up and shows the boot errors or some like this.

This problem most probably occurs due to file system corruption or volume corruption. The file system or volume can get corrupted due to a number of reasons including improper mounting of hard drive, unexpected system shutdown, virus attack and many others.

It doesn’t matter what the reason of file system corruption or the error messages is. The only and the most important thing that matters is your precious and significant data. All of your data is at stake of loss and it can possibly put you out of the business.

In order to save you and your business, you need to recover your data. The data recovery is feasible by using Linux recovery solutions. Linux recovery solutions are available in the form ofLinux data recoverysoftware to perform data recovery Linux.

Linux data recovery software are the easiest, cheapet and quickest solution of data recovery Linux. These software can be used in each data loss situation to recover all kinds of lost data. You should opt for the good data recovery software to prevent further data loss and carry out absolute data recovery Linux.

You can recover data from all Linux flavours such as Red Hat, SUSE, Ubuntu, Linspire etc. using this data recovery Linux soon.

Linux Data Recovery Using ‘myrescue’ Utility

By blogger on

In Linux operating system, myrescue is an utility to retrieve still-readable information from damaged hard drive. This Linux Data Recovery tool is similar to the dd_rescue, however it attempts to quickly get out of corrupted area to handle undamaged part first. After extracting data from the undamaged area, the utility then returns to the damaged area and tries to fix it.

The myrescue utility attempts to copy your hard drive block-wise to the file and creates a block bitmap (table) remarking whether the block is successfully copied, not handled yet or it has errors. The block bitmap or table can be employed in the successive runs for concentrating on unresolved blocks.

This Data Recovery Linux utility effectively handles the read errors, through its special skip way. General the hard drive surface blemishes cover more than simply one data block and uninterrupted reading data from the defected areas may damage the hard drive surface, the hard drive mechanisms, and read/write heads.

When it occurs, the possibilities of retrieving the remaining and undamaged data decreased dramatically. Therefore in the skip mode of myrescue, it attempts to escape the damaged area quickly by exponentially incrementing the step size. It marks the skipped blocks as un-handled in block bitmap table and they may be retrieved at later stage.

Ultimately, the utility has an advanced option to multiply attempt for reading data from a data block, before believing it is damaged.

However, you should bear in mind that this utility is not a replacement for third-party data recovery utilities. When you have a second option, do not even try to use myrescue, as the tool may cause more damage to your hard drive.

The myrescue utility is available only for the situation that you’re completely desperate and cannot afford any professional Linux Recovery utility. If your data is highly significant for your business, it is worth to go for professional recovery applications.

The Linux Data Recovery softwares are able to handle all types of data loss situations, ranging from simple deletion to the most severe file system corruption. These applications carry out in-depth scan of entire Linux hard drive and extract all lost, missing and inaccessible data from it. It comes equipped with simple and efficient GUI, to allow you to carry out Do It Yourself recovery.

Stellar Phoenix Linux Data Recovery is the most familiar and powerful program that ensures absolute recovery of all your lost data. The software recovers data from Ext4, Ext3, Ext2, FAT12, FAT16, and FAT 32 file system volumes. It is compatible with all major distributions of Linux operating systems including SUSE, Debian, Red Hat, and Fedora.
