10 RAID Is Not a Backup
Because RTX features redundant RAID modes which protect against a hard drive mechanical failure, it is
an excellent part of any backup strategy. However, a RAID is not, in itself, a complete backup strategy.
Many things besides hard drive failure can damage or erase your data:
• Corruption caused by unexpected disconnection during data access (e.g. a cable is unplugged
during a data transfer, or the computer crashes or loses power while writing to the drives)
• Corruption or destruction caused by viruses or other malware
• Sabotage by a disgruntled employee or acquaintance
• Theft of your RTX
• Natural disasters such as fire, flooding, etc.
Considering these possibilities, any single copy of your important data must always be considered at risk.
That's why backing up is so important. Follow the 3-2-1 backup rule. Data should exist in three different
places on two different storage media and at least one of those copies should be maintained offsite.
Without an effective backup strategy, recovering data may be impossible, or the cost of data recovery
may be quite expensive. The CRU warranty does not cover costs associated with data loss (nor do the
warranties of other hard drive manufacturers).
Plan accordingly and backup data to minimize downtime!
