Hello,
First, I know what you're thinking: "NAND is the worst for backups! do LTO!" but I have a specific use case.
USE CASE: I have my multimedia (movies, shows) already hosted and with redundancy on a server and it doesn't worry me. The movies I really like I even have a physical copy of them (blu-ray) so I'm OK with it.
But I have a bit of data (about 300GB or so I think) that are just documents, emails, family pics/vids, business data, personal (health, financial...) data that I really really want to protect. If the multimedia data one day disappears I won't cry (example: fire on the house) but about this data? I would certainly lol.
My current approach is having all the data on "the cloud" (Google Drive) - some of it encrypted with cryptomator because sensitive info. Then, it's kept synced with my laptop (GDrive for Windows), and with the multimedia server (rclone), which keeps a local (un-encrypting the data just to have it if cryptomator corrupts it one day) + BackBlaze B2 incremental backup (duplicacy encrypted) - also, I burn a Blu-Ray with the most precious data if I feel like it.
But I want to keep a copy with me at all times, I think it would be nice. For example, being on a light-baggage travel, at work or whatever and be able to access the data even if there isn't internet. My setup would be having 3 partitions on that disk: 1 for clear data if I have to share something with another person without having to give passwords, 1 encrypted (bitlocker) with business data, and 1 encrypted (bitlocker, another pass) for all the personal and family data (so if I need it at work, I can use it without opening personal files).
Problem is I don't know what is my best option:
- Samsung Fit/Bar Plus 256/512GB pendrive (45€/$50 for 256GB - I think I could limit myself to 200GB?)? I see they are the best pendrives out there, Samsung sells they are physically strong (water resist, X rays, hits, whatever) and have 100MB/s witing speed and 400MB/s, which reviews tend to say it's true. What worries me is... wouldn't that pendrives be unreliable? I usually read here that pendrives can't be trusted and so on, even if they use TLC memory, they don't have a controller so they just go on until they fail, don't have TRIM, wear leveling... I worry if it would be a bad investment. BUT It would be the smallest option to keep in the wallet for example.
- Transcend ESD310c 512GB (64€/$70)? I see it's a bit bigger, but still pendrive-size, and is a full SSD? It has a Silicon Motion's SM2320 controller and Kioxia's BiCS5 112L 3D TLC NAND, up to 10Gbps. IDK if it would be easily ported on a wallet (maybe? seems small enough) but it also has dual interface which is nice (USB-A and USB-C) and aluminum body (even if I don't like the plastic parts covering the ports). But... it's Kioxia NAND reliable? Would this option be better than the Samsung pendrives?
- Samsung T7 Shield 1TB (100€/$110 for 1TB, 150€/$163 for 2TB)? This would be surrendering the idea of going for a small-size option and just going for what could be considered the most reliable out of this three? Also the most expensive.
At the end, my setup would be: working with files on the cloud, sync daily with the home server, which will make 1-3 months of incremental backups (with sensitive folders being unencrypted) and upload a copy of this local incremental backups to BackBlaze B2 (encrypted copy)
And, manually, regularly, making a manual copy of all that data (and cryptomator files unenrypted) to the pendrive/SSD chose from the last 3 options I described.
What do you think? Tips? Also, if you think I'm overthinking anything tell me. For example, I was thinking of dropping the BackBlaze B2 backup copy, thinking that having the cloud -> local server -> SSD/HDD would be fine.
Also I think if I just am overthinking the encryption thing and should drop Cryptomator for Google Drive just for some excels with financial info or family data - that way, I protect myself from another weak point (Cryptomator failing without me noticing) and make easier the process of backing up?
Thank you all for all your tips/help/POV
