Whilst attempting to backup a linux system to a tar archive to a machine across the network, I hit a 2GB max file size limit. The target machine is a windows machine with a 500GB drive shared over the network as 192.168.1.133/shared_c. I had previously mounted it with `smbmount` or `mount -t smbfs`. I was able to transfer large files by instead mounting the share with the -t cifs argument, like so:

 mount -t cifs //192.168.1.133/shared_c /mnt/htpc/shared_c -o username=Administrator,password=TheAccountPasswordHere

This also would have been equivalent:

 mount -tcifs //192.168.1.133/shared_c /mnt/htpc/shared_c -o'username=Administrator,password=TheAccountPasswordHere'

This solved the problem! With the -tsmbfs command, it would abort with "file limit exceeded" once it reaced 2 gigabytes. However, after mounting with the -tcifs filesystem type, things are looking good at > 2 gigs.

Happy holidays!
