Hey bootsz, when your connection is down, you'll still have a local cache of your messages, contacts and calendar events. Email has retry built in and sending servers typically retry for at least 48-72 hours. The hardware has no moving parts so it should last for a long time, but when there is an inevitable failure, there are encrypted backups that can be downloaded to a replacement device and decrypted using keys only you have access to.
