I had a tar file which was of size 3.5gb which held all my programming code.
I was working with git trying to learn the repositories, so I created this file as a backup, so I could work my code directory and if anything were to go wrong I could just delete and extract it.
I did this a few times and it worked great, then I restarted and remounted my drive and the tar file was not 10kb instead of 3,5gb and all its contents were gone.
What could have happened?
