I think your only hope is to try and get the attention of someone higher up. They MAY have archives of this data recoverable, and MAYBE they can restore it without costing them an arm and a leg as a special one off if this gets some traction. However I do know providers like this tend to run as lean as possible, so I could also imagine they wouldn't explicitly try not to hold any data longer then strictly necessary as not only does that storage cost, it would open up having to spend time and resources providing it to law enforcement when demanded. I don't think personal credit limits is likely to occur. Companies wants to have the lowest amount of receivables possible, especially if they are looking for valuations. I think snapshotting and archiving this data for 90 or 180 days is more reasonable for long term customers of good standing (hell it probably would be worth it for retention). If you get the data back, you might want to look at having a way to download the snapshots at least once a week, even if you just hold 2 on your development machine. Its not ideal, but it would at least limit the loss. Finally if you are charging a customer (assumed from the "service provider" usage), I would suggest looking at seeing if you can increase you price to cover storage on another provider.
