Hi Tiago,

It all depends how the files were backed up.

If you used relative pathnames, then cd into the directory before restoring.

If absolute, then, depending on the original directory, you could create a soft link from the old directory to the new directory before restoring.

Hi,

just specify the file name to be extracted. If the path exist in the system where you are extracting, file will be extracted in that path, other wise system will create the extracting file's path.

Hi Tiago,

If you created the tar file using relative pathnames for the input files, tar will extract the files to locations relative to your current directory.

If you created the tar file using absolute pathnames for the input files, tar will extract the files to that absolute path.

An alternative for changing the extract destination for a tar file created with absolute pathnames is to use pax. An example is:

tar cvf /tmp/users.tar /home/users

tar xvf /tmp/users.tar
will extract files back to their original locations because the input file/dir was specified with an absolute pathname (/home/users)

pax -r -s,/home/users,/home/users2, -f /tmp/users.tar
will extract files changing /home/users to /home/users2

See the man page for more info.

Did you have a space between the last comma and the minus f? The -f is a different option from the -s with its replacement string...
