So... When they inevitably push an update that borks your system, you will definitely will be prepared and ready to jump to another OS cause you definitely had time testing and making sure everything works on them and not just be caught with your pants down.

UPS Recommendations in c/selfhosted@lemmy.world

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.

Cocaine is probably cheaper now. You should check the market prices. /s

NAS vulnerabilities in c/selfhosted@lemmy.world

[–] zer0squar3d@lemmy.dbzer0.com 1 points 2 months ago

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.

Works now! You should setup SSL which is super easy with Let's Encrypt.

I have a HDD 4tb Toshiba drive I had in a Raid 1 NAS device (NSA320) that failed in the raid and I replaced it and rebuilt the raid and life was good.

I have finally moved to a better custom TrueNas scale setup with 2x 8tb HDD in a Raid 1 with weekly encrypted backups to online cloud. I have 2 4tb Toshiba HDDs that match closely with the dead hdd.

I want to try to recover data from it mainly because I want the experience... Let me explain. The drive clicks, yes you can hear the disks spin up to speed and then you hear clicking as it's trying to read.

I want to know if I can start off trying to swap the circuit board to rule that out without much issue? I have true HEPA filter air purifiers and I can rotate and angle them to have a positive pure air pressure if I need to open it up and swap out the arms.

Is it worth trying? Anything I should know or think about in my decision to try this?
