"This sum included $24,000 for security, $29,000 for staff wages and $28,678 for general costs. Among the general costs was a monthly power bill of $8500 and $6000 per month in phonecalls." http://www.stuff.co.nz/auckland/local-news/6501320/Dotcoms-expenses-through-the-roof

The money that Kim Dotcom requested is used to pay for the mansion that he is renting (due to being denied purchasing land in NZ) which is somewhere in the vicinity of $20k per month and he also has to pay for the huge phone bill from calling the United States to his defence team - the cost of which is about $0.33/minute which makes 60 minute call cost $19.80. If he's on the phone for 3 hours a day, 7 days a week then in 30 days his phone cost is over $1600.00. The security guards, butler and nannies also need to be paid.

The best method is multiple solutions. Hard drives fail, devices break etc. -- If you truly want to have a copy of these video files in 10, 20, or 30 years then the best solution is to backup using 2-3 different methods. Using a FTP like people recommend is a good solution, DVDs (stored in a secure box (preferably a fireproof one or one stored at a bank/similar,)) and keeping a external hard drive with a copy of the files means that if the server that you are hosting gets hacked into and all of the files deleted, your house burns down with all of your stuff inside then you still have a copy elsewhere and you don't lose those videos forever.

With Facebook, you are guaranteed to NEVER, EVER, have it deleted.
