Right, but the OP did not say, on what kind of system he wants to untar the tarball. If it is not Solaris, then it will most likely not be possible. And it might be helpful, to know this in advance.
the strange thing about this is that, i had a similar batch job on a Solaris 8 box tarring up at least 70-80 gb using -cvf without any problems. but on this Solaris 10 box i can tar 70-80 gb without using the cEvf.
I am not sure what platform the recieve of the data is using. i am presuming it is solaris
The whole archive size isn't your limitation here. The issue might be individual files larger that 8 GB or having a full path larger than 255 characters.
