Backup the existing previous file

[Priednis]

I was actually hoping that the plugin saves (backs-up) the version of the file before my current changes. Is this functionality available or considered?

Meaning if I open any existing file and make a modificiation to it and save it, I would like that old version to be backed up (assuming I have not done this with sublime + automatic backups before). Otherwise I have my change backed up but I still have no way of going back to that previously existing version.
