I assume you're configuring the FPGA directly using a '.sof' file...

FPGAs are volatile devices - they have no FLASH. They store their configuration image in SRAM while operating. SRAM doesn't store anything when you power them off.

Should I do something special in order to keep the programming data

Read through Chapter 8 - 'configuration, design security, and remote system upgrades in arria v devices' - of the arria v device handbook (https://www.altera.com/en_us/pdfs/literature/hb/arria-v/av_5v2.pdf).

Cheers,
