Tar is taking multiple files and combining them into one...

This is mostly bound by disk I/O - does tar have any idea how much data and how fast your disks are? What if you have a *really* slow CPU which could affect things as well?

Simply put - no, tar doesn't take these things into account.

IF you have a *best guess* on your system where you measure and say, on average, 5GB takes ~5 min to tar, you can write your script to check the amount of data, scale the average, and then throw out an estimate before it calls tar.

For all of the tar options:

man tar
