    Yeah no, line voltage will kill you if you don’t know what you are doing, not to mention the fire hazard as was mentioned. The 12/24 volt used in computer systems much easier to mess around and not ‘find out’ other than maybe a fried component. Unless you are an electrician/ electrical engineer with proper training don’t open/mess with Power Supply Unit (PSU) or UPS.

    One mod anyone could do is swap their lead acid for a LiFePO4. You just need to make sure the same voltage,battery quantity (larger backups often have 2 batteries in a series) and the battery dimensions are the same. They should be drop in replacements and do last longer.

    That being said, I myself, do have training and if you want to waste your time I probably would mod some UPS with a car battery for longer down time support. Watched a YouTube video of a person do it to find the pitfalls for me and the issue is heat as it’s not expected to run off battery + inverter for longer than the smaller battery normally allows it maybe 5 minutes compared to like 1 hour, so several fans and heat sinks on critical components would be needed adding minor complexity and planning.

    Yeah, I actually finally got rid of mine a year ago, but it never was allowed to access the Internet. Also didn’t support smbv3 when those huge issues came out so has to use custom package sources to get updates. Never buying something unless it can have open source firmware flashed any time for my NAS hardware. Using TrueNAS now on slightly old custom built PC I upgraded from.

    I see your valid points. However, my point regarding backups being in a trust worthy area still stands. Idk why you would chance it by doing this. Besides that there are other reasons I will point out which I assume is their reasoning, statistically, is that Windows users tend to be a ton less savvy than Linux users, so they would be only backing up what is available on their system, and I bet on average they don’t have more than 1TB drive with maybe 300gb if storage used that needs to be backed up, like pictures which is equivalent to the 1TB a month plan which I am assuming is the cost of the windows unlimited plan. If you want to screw over companies with exploits, please do so the evil/terrible companies; otherwise this makes you look like an asshole. My 2 cents, and no I don’t work for them.

    TL;DR - average windows user most likely uses no more than 300GB so offering an “unlimited plan” to them to make money on under-utilized plan makes business sense.

    Awesome and hopefully they never find out as that’s against their TOS. Sticking it to the man for what? ~$20 a year, potentially losing your backups and not having any if they find out? Why would you want to potentially lose your backup service over this? Idk why but this seems dumb. The point of 3-2-1 is to reduce points of failure and you are increasing your potential of data loss by doing this.

    Yeah… That probably because either the drive thought it was falling and triggered the HDD falling mechanism (often found on 2.5" hdd) which would move the arms off the disks to prevent them from hitting it and damaging the platters to unrecoverable states.

    Or if done on 3.5" without this feature built into it, could just damage the platters.

    Would probably be less risky to open it up and unstick the arms yourself.
