- Contact Rackspace support.. That’s what they’re there for.
- Do everything they suggest.
- If that doesn’t work, try Dan’s suggestion of data recovery software.
- Use this as an opportunity for growth and learning.
Always ensure that all your servers are backed up, and test the backups regularly. There’s no point in having a backup service if you never actually test that you can restore from it.
Oh, and turn off automatic updates. Only ever do them once you’ve tested the impact of the update, preferably on another identically configured server.
