To verify the integrity of compressed tar backup, use followingįor. In case of corruption, we will get the output something like below, If above command does not generate any output on the screen then we can say that there is no corruption. $ sudo tar -xpvf system-back.tgz -C /var/tmp/įor tar ball, use ‘-tf’ option and redirect the output to /dev/null file, $ tar -tf system-back.tar > /dev/null In the following example we are extracting system-back.tgz in /var/tmp folder.
