Linux Help Getting Error: tar: web/log/error.log: file changed as we read

Today i was backinup up a website in linux shell command though my ssh sesion, i send the tar command, waited a little while, then i got a respond back that said:

so what now? What happened? What went wrong? Did my file was copied? WHy this error come up? these were all questions on my mind.

But i found out that Linux created the tarball file, when i unpacked it, i saw that all the files were created, i guess during the the creation of the tarball, my system wrote a erro in the error.log file and that's why i got this error: tar: web7/log/error.log: file changed as we read it

so if you are also getting this error, no worries, its ok. your tarball file should have been compressed/created fine.
