    Planning to upgrade my 4TB homelab storage to a bit more since it's almost full and whilst getting 2x14TB refurbed SAS HDDs and a controller is easily and somewhat cheaply doable...

    What about backups? 14TB could be backed up by a single 20TB HDD with room to spare for differential backups, not too bad. But going just one drive more to 28TB usable storage (2x14TB + 14TB parity), you'd have to do RAID on the backup server too or pay like 500+ bucks for a HDD large enough, dang... :neocat_think:

    And doing RAID on the backup server would not only mean paying more than double for what the actual server HDDs would cost to have at least the same amount of storage, but also paying a lot more for power if the drives run 24/7, which probably comes out to around the same 500 bucks that a large enough HDD would cost (like those 28TB Seagate server drives).

    Maybe 14TB is enough for an upgrade for now... :floofWoozy:

    And as cool as tape backups might be, getting a modern enough drive which supports tapes large enough to actually fit those 14, let alone 28TB, even in compressed form on them without breaking the bank is wishful thinking at best :v

    @snep Hard drives use very little power, so I don't think you'll run into issues there.

    I have 10 spinning rust drives and my power bill is peanuts.

    @FrenzyBiscuit Mm, with close to 40 euro-cents per kWh, I'm rather cautious what I'll run 24/7, especially if it's older server drives, as those tend to be ever so slightly more power hungry :neocat_laugh_sweat:

    Like the Seagate Exos X14 I'm looking at, for example. If I went with 7 of them (three for the primary server, four for the backup server), I'd be looking at 7*5W at idle, which already would be at least ~10€ per month. Not horrible, but noticable on the "homelab power bill", so to say

    @FrenzyBiscuit (Which, in its current configuration, is already at around 30€/month, plus whatever I pay for domains, VPS servers, online backup storage etc. on the side)
