You are responsible for your backups and web content.
We create our own weekly backups on the servers, and we can restore from those. However, this is NOT a procedure you should rely on to keep your content safe. Backups made every Sunday; only the newest backups are kept. We make no guarantees about our weekly backups, and we do require a $20 fee to restore the W3rack backups. If you can provide your own backup file, then the fee is $0, free.
For your easiness, we offer one click backup option in cPanel.
