I have space available in SoftLayer Dallas on our R1Soft Backup server.
$50/month gives you 250gb of storage
$25/month gives you 125gb of storage
These are for single servers only (meaning 1 250gb backup account can only back up one server).
You have to pay 4 months up front on the 250gb and 8 months up front on the 125gb and then you are welcome to go monthly. This is to cover the cost of the R1Soft license itself. The up-front cost (4 or 8 months) is $200.
If you have any questions feel free to post here, contact me directly via PM, or to contact sales and ask for me.
