Might I suggest the following:
If you need high availability, look into technology enabling access to your sessions using a quick RAID 10 volume. Don't ever forget about making backups. RAID isn't a backup solution (as if you hadn't heard that yet). At least one local backup to a high availability RAID 6 volume, as a Drobo dual disk redundancy setup. Then an encrypted backup to some proven cloud service.

The backups should be controlled by an account with higher or other rights than your personal/active user account. Separate yourself from being able to manipulate the backups so that you don't get caught by some nasty malware.

Good luck!
