Backup Phabricator database and uploaded files every 24h to Trithemius.
We now have a script (/usr/local/bin/phabricator-rsync-backup.sh) that backups the database, repos, local config and uploaded files. Everything is compressed and rsync'd to trithenmius. I installed a cronjob that runs the script at 2:00 am. I'll keep the issue open until I'm sure the cronjob is reliable.
