How to avoid sudden shutdown from power outage?

Last modified date: 2026-01-06

Applied models:

All NAS Series

Applied Firmware:

Any version

If city power or building power would cause power outage, it would make QTS system cannot flush data before power-off and cause filesystem getting corrupt. If possible, install a UPS device to connect between power socket and NAS and let NAS has enough power to shutdown while power loss. If filesystem got “not clean”, please remember to run filesystem check ASAP. (compatibility page https://www.qnap.com/en/compatibility/)
