One important item I wanted to tick off as early as possible is backups.
Markfolder's users have entrusted me with their data and I want that to be fully respected. Making sure they never lose their data is the least I can do (followed by security of their data and their privacy, which I'll continually work on).
So now, at 00:00 every night London time, a backup of all code, files and database is made, zipped, and saved to an Amazon S3 server in the UK. Having the backup on a server separate to the web server ensures that if anything happens to the website, the backup is still safe.
