Three-tier encryption secures data in-transit and while in storage.
Only pay for the storage you use.
Time backups to suit your needs and choose what data to store.
In the ever evolving cyber security landscape new vulnerabilities are found and exploited daily. Crypto Locker ransomware is an example of the new kind of threats you face. Once infected, it finds all personal files and encrypts them, requesting you pay a ransom to unlock your files. This would not be wise. They may use your payment information for identity theft and never return your data. The only real solution is to restore from a backup.
No backup, No data recovery. It is that simple.
