    History

    I decided to suspend the file server during the daytime on weekdays to save electricity, so I have to manually cancel the suspend on a public holiday weekday.

    Less than half a year to move the PC to homebrew NAS. Because of lack of budget, My NAS has single HDD,
    but now, I want to buy additional HDD and build mirroring to save my data

    At first, i was going to build a raid1 with ext4 and motherboard function, but after research, I decided to install a file system called ZFS. The reasons are following,

    • The file system itself supports RAID
    • Many useful functions such as transparent compression and snapshots
    • It eats cpu and memory, On the other hand, I can think that make good use of my NAS’s specs.
