How to preserve symbolic links especially when you tar the files is explained below. We all know how to use tar command. Below option shows the way to preserve links when you archive.
# tar -cvhf archive.tar /backupfolder
Note: What you need to remember is that when tar archives a symbolic link, it writes a record to the archive naming the target of the link. When you use -h with -c, it causes tar to archive the files symbolic links point to, instead of the linking themselves. When this option is used, when tar encounters a symbolic link, it will archive the linked-to file, instead of simply recording the presence of a symbolic link.
