Hi,

You must to do these steps :

1.- tar tvf /dev/XXXX : Indicate if the files are saved with absolute path o relative path. If the name of each durectory/files begins whit the caracter slash "/" (/unix) it's means that is a absolute path, these files are restored in the same path that indicate. Whenever, if the name of each directory/file begins whit the caracter point "./" (./unix) it's means that is a relative path and before you restored these files you must be in the destination path.

2.- (Only to relative path). You choose the destination directory.

3.- Restored the files.
