For me its honestly a ton of my work software (digital forensics), shit is too niche to be replaced by good FOSS options. Cellebrite, Magnet Axiom, etc. Autopsy is great and free and has a linux version but it simply cannot get the same level of data without a pretty nutty level of custom code.
And the biggest side effect of this is FUCKING WINDOWS. God I would replace this nightmare OS in a heartbeat if the aforementioned work software would make linux compatible versions. We have legitimately wasted 10k hours dealing with windows bullshit that would not be a problem in linux. Though im sure linux would take a different 10k for its own problems.
What about you guys? Doesn’t have to be work related, thats just the thorn in my side right now.
NextCloud is probably the best option but prepare to pay for storage. You’ll need a NAS with at least two HDDs and personally I would also pay for cold storage to have offsite backups in case something happens to both disks.
I’m going down that route now and at a glance, a 18TB setup will cost me at least $700 (local currency) all in all. ~$400 for the disks and another $300 for the server.
