Direct Alteration Of Unionfs Branch May Cause Data Loss In Linux

For easy and effective management of your valuable data in Linux

, it could be useful to use related but varying set of files on separate memory locations. You, however, might prefer to see the relevant files together. In such cases, unioning the file system allows you to keep these files separate physically, but merge them logically in single view. This is possible through UnionFS command.

The union file system is a combination of two or more file systems to create illusion of single file system with contents of all others. Using this, you can get several file systems mounted at the same time. But in some situations, this command may damage the file system can cause serious data loss situations. In these situations, Linux Data Recovery is requited.

The major function of UnionFS command is to allow files and directories of various file system to form single file system. Such files and directories are called branches. To create a virtual file system, the branches are merged. In this, contents of the files and directories that have same path in branches would be seen together. When you mount the branches, a priority level is set among them.

Although, this method is very helpful to merge various Linux file systems, but critical situations might take place if you directly alter the UnionFS branch. It could even cause severe file system corruption and data loss situations that need Data Recovery Linux to be handled.

Data loss may occur in one more situation. If the merging of branches is done with the help of UnionDS command, after that the pivot-root or the switch-root is done, by setting / to new pint in current file system hierarchy. It doesn't allow you to properly remove UnionFS-layers during system shutdown. At this point, mounted Linux file systems could not be mounted correctly and thus the file system corruption occurs.

In any of the above situations, data loss can be handled by performing Linux Recovery. The recovery is best possible with the help of comprehensive third-party applications, known as Linux Recovery Software. The tools allow you to carry out recovery on your own as they have rich graphical user interface. They never alter original data on the disk as they have read-only behavior.

Stellar Phoenix Linux Data Recovery is the most robust application to effectively handle all data loss situations. It recovers data from Ext4, Ext3, Ext2, FAT12, FAT16 and FAT32 file system volumes. The tool is usable with most of the Linux distributions including Red Hat, SUSE, Ubuntu, Fedora and Kubuntu.
