A home NAS carries the important responsibility of storing and sharing valuable data such as photos, videos, and documents. So, do we need to equip a home NAS with a UPS?
I. Data Security Risks for NAS
NAS typically uses mechanical hard drives as storage media, which have relatively high requirements for the stability of power supply. Sudden power outages or electricity cuts may damage the hard drives, leading to data loss. This risk cannot be overlooked, as the lost data may include precious family memories and critical work files.
II. How UPS Ensures Data Security
Provides Backup Power
A UPS can supply backup power to a home NAS for a period ranging from several minutes to several hours after a mains power outage, allowing the NAS sufficient time to shut down safely and thereby avoiding data loss during the power interruption.
Protects Hard Drives
By providing stable power, a UPS can reduce damage to hard drives caused by sudden power outages or voltage fluctuations. This helps extend the lifespan of the hard drives and ensures data security.
Automatic Shutdown Function
Some UPS units are equipped with a USB communication interface that can connect to a home NAS. When a mains power outage occurs, the UPS notifies the NAS through this interface and triggers an automatic shutdown procedure. This way, even when no one is present, the NAS can shut down safely, ensuring that data remains intact.
