How to save variable?

I save last market session information in a variable.

How can I save it to a file in case of a live server update or shut down?

I need to load it back if there is a saved value.

Thanks

Hi, I store my configuration/serialization data at Amazon S3. I'll try post an example in the weekend, however setting up S3 bucket with appropriate access permissions is a bit of work and not something I've memorized how I did.

I've suggested to QC developers in the past there should be some kind of "save to virtual file system" function for this, since it's sometimes needed for training or configuring algorithm with a backtest prior to launching it live.
