What is this doing in my root folder?

Ok, my host recently added .tar zipped file in my root folder. When I opened it with winzip, I noticed it had all the files on my site.

Any idea why did they put this .tar file on my site? Is it a backup generated by my host?

Sounds like a question for your web host. However- it does sound like that's where they dumped your backup.

That's exactly what I thought.... I am almost 99% guarantee that it is some type of backup done by the host.

That is not typically where a host would store it
Most have another drive for backups
What if the drive your site is on fails???
Your backup .tar also failed

Yeah, I'm not sure why they put that .tar file there. They just recently moved me to their dedicated servers, that's when I noticed the mysterious .tar folder in the root. I deleted the .tar folder from the server since I already do backups on a daily basis.
