[root@itsupport ~]# tar --update -f ramkannanbkup.tar workers.properties
tar: This does not look like a tar archive

Thanks,

how you created the tar file.
This error is seen when you rename the some other compressed file format to .tar.
eg mv test.zip test.tar

test the command.
are you able to run
tar -tvf file.tar

I have created a tar file using the below command

tar -cvzf ramkanannbkup.tar /linuxdocs

After that only i was trying to update worker.properties to ramkannanbkup.tar by using the below command and i got the error

[root@itsupport ~]# tar --update -f ramkannanbkup.tar workers.properties
tar: This does not look like a tar archive
tar: Skipping to next header
tar: Archive contains obsolescent base-64 headers
tar: Read 2535 bytes from ramkannanbkup.tar
tar: Error exit delayed from previous errors

Thanks,

I suggest not repeating the same information---we can see it in your first post.

Your command (tar -cvzf) created a tar archive AND compressed it using gzip). To append to the archive, you would have to first uncompress using gunzip.

take a note:

when u use -z switch give file name. .tar.gz

tar -cvzf filename.tar.gz filename

That was the reason the format of file was incorrect
