I have a couple of home made (non enterprise) servers with backup HDDs installed on them.
Since the purpose of these HDDs is only to store backups, I only use them at the time of performing the backups themselves, so is it a good practice to unmount the disks after making the backups and then mounting them back before making the next backup?
The idea behind is to extend the life of the HDDs avoiding disk usage (read/write) by any kind of process and maybe reduce a bit energy consumption although disk still consumes.
HDDs are internal and cannot be external, so it is not feasible to unplug the disks at any moment.
Unmounting/mounting drives to extend their life is considered since it is an automatable process.
