prevent, gradual corruption caused by the slow degradation of the disks; and cannot provide protection from
a site disaster. Snapshot technologies provide protection against accidental deletion or corruption but by
themselves cannot protect against disk loss or site loss.
ReadyNAS OS allows you to use five different types of protection simultaneously:
• RAID. Protects against disk failure.
• Snapshot technology. Protects against accidental data deletion or corruption by providing point-in-time
recovery.
• Real-time antivirus. Protects against loss or corruption from viruses.
• Bit rot protection. Protects against the degradation of data from disk aging.
• Offsite backup. Protects against site loss.

Safe Mode
For normal operation, ReadyNAS OS requires access to the disks on the ReadyNAS system. If for any
reason, and at any time, the disks are not available, ReadyNAS OS enters its safe mode. While in safe
mode, ReadyNAS OS displays messages showing the problem.The most common reasons for the disks
not being available are that no disks are installed, disks are present, but they are not formatted, or disksare
present, but the disks are formatted for another type of system.The system also enters safe mode if hardware
problems occur, or the OS itself is corrupted.
When the problem is resolved, for example after you add disks or reformat them, ReadyNAS OS resumes
normal operation.
