How to TAR file of 500 GB to an External Drive

We have one TAR file of size 500GB. We want to put this file in an external drive for a backup purpose. Through tar we can't do it as tar has the limitation of 8GB. What are the other ways to do it. Later on we want to put file again on the server from external drive. Please suggest how to do it. Thanks in advance.

Re: How to TAR file of 500 GB to an External Drive

if the file is already tar format, simply use cp or dd

Why would you want to use tar on a tar file?

dd(1).
What do you mean by an external drive? What type of filesystem does it have?

Re: How to TAR file of 500 GB to an External Drive

I've heard of a disk drive, a tape drive, and
a scenic drive, and I know what those are.
An "external drive" remains a mystery.

How did you get it?

> [...] Through tar we can't do it [...]

So, how did you get this 500GB "tar" file?
(GNU "tar", by the way, has no 8GB limit.)

It might be helpful if you explained the
actual problem which you are trying to solve,
rather than asking how to implement some
sub-ideal solution to that problem.

Re: How to TAR file of 500 GB to an External Drive

Since copying a file of any size (TB) from HP-UX to a another directory is the simple cp command, there must be some details you are leaving out. Is the external drive connected and working (ie, has a filesystem and is mounted to your HP-UX system)? Whether the file is 500GB or 2TB makes no difference to the cp command. And whether the file is tar format or random data again makes no difference.

If you already have a tar file, why would you want to use tar to copy the file?
