What's the current thinking regarding power management for a NAS that is used less than 30-minutes every 24-hours, solely for backup? We have a DS1819+ backup NAS with 6x16TB Exos drives - currently running 24/7. I've read and understand comments on this forum and elsewhere regarding the merits of 24/7 to reduce HDD wear and tear. But is there a tipping point for low-usage systems, where cycling on/off as needed makes the best sense?

Comments regarding power vs. hibernation strategy are also welcome.

Thanks for your thoughts.

My backup NAS only has HB Vault installed. It is regularly in hibernation. That works for me. Power schedules unnerve me.

Just schedule it on/ off, saves energy and gives better protection against attacks.
there is no proof (just opinions) that there is wear/tear as result of on/ off switching.
