It is no secret that I am a pretty big fan of excellent Linux Software RAID. Creating, assembling and rebuilding small array is fine. But, things started to get nasty when you try to rebuild or re-sync large size array. You may get frustrated when you see it is going to take 22 hours to rebuild the array. You can always increase the speed of Linux Software RAID 0/1/5/6 reconstruction using the following five tips.
Some time ago ext4 was released and available for Linux kernel. ext4 provides some additional benefits and perforce over ext3 file system. You can easily convert ext3 to ext4 file system. The next release of Fedora, 11, will default to the ext4 file system unless serious regressions are seen. In this quick tutorial you will learn about converting ext3 to ext4 file system.
Wow, this is a large size desktop hard disk for storing movies, tv shows, music / mp3s, and photos. You can also load multiple operating systems using vmware or other software for testing purpose. This hard disk comes with 5 year warranty and can transfer at 300MB/s. But, How reliable is the 1.5TB hard disk?
TrueCrypt version 6.0 has been released and available for download. It is free open-source hard disk encryption software for Windows Vista/XP, Mac OS X, and Linux system.
You can use tar, split and md5sum to backup large files (30Gig or more) easily under Linux / UNIX operating systems.
The guides are designed to give instructions and recommendations for securing Mac OS X and for maintaining a ultra secure computer system.
One of the most popular remote server management service has just released security fix version. This version avoid possible hijacking of X11-forwarded connections by refusing to listen on a port unless all address families bind successfully.

This is an excellent backup utility for new Linux user.
Apple’s Time Machine is a great feature in their OS, and Linux has almost all of the required technology already built in to recreate it. This is a simple GUI to make it easy to use.
Time Machine, like many backup utilities, creates incremental backups of files which can be restored at a later date. It also supports limited restoration of files within applications that are specifically programmed to use Time Machine’s functionality.

You can easily clone single hard disk or partition using netcat and your own network. However, software such as Clonezilla offers a partition or disk clone software similar to Ghost. It saves and restores only used blocks in hard drive.
This software is must if you dual boot between Linux and Windows laptop / desktop computer.
I’ve already written about Explore2fs and other programs to grant read and write access to Linux ext3 partitions / files from a Windows box. There is a new program called Linux Reader which allows safe and quick access to alternative file systems. This program plays the role of a bridge between your Windows and Ext2/Ext3 Linux file systems. This easy-to-use tool runs under Windows and allows you to browse Ext2/Ext3 Linux file systems and extract files from there. From the project home page:
First of all, DiskInternals Linux Reader is absolutely free. Secondly, the program provides for read-only access and does not allow you to make records in Ext2/Ext3 file system partitions. This guarantees that the interference in an alterative file system will not affect the work of Linux later. Apart from this, it is necessary to note, that it gives you an opportunity to use common Windows Explorer for extracting data. A preview option for pictures is one more pleasant point, which is worth mentioning.
