Quando ho letto l’articolo sulla “perdita dati negli #SSD non alimentati” mi si è gelato il bus di sistema. In pratica: gli SSD sono fulmini quando lavorano, ma se li lasci troppo tempo spenti e dimenticati in un cassetto, col passare del tempo e della temperatura possono iniziare a perdere colpi e… bit. Non proprio l’ideale per i backup “da tenere lì e sperare che vada tutto bene”.

#Snowfan.it è la mia piccola astronave nel #fediverso e non ho nessuna intenzione di vederla esplodere perché un SSD “a riposo” decide di fare harakiri silenzioso.

Da qui la scelta: affiancare un onesto vecchio HDD da 4 TB come QUARTA linea di difesa.

Oggi la situazione è questa:
– un backup quotidiano sul server stesso
– un backup quotidiano su un mio SSD locale
– un backup settimanale su Proton Drive nel cloud
– e ora un backup settimanale su #HDD esterno, che collego solo quando serve e poi metto al sicuro in un luogo fisicamente separato.

Sì, lo so: è ridondante, paranoico, sopra le righe. Ma l’alternativa è affidare anni di Fediverso, amicizie e storia digitale all’umore di qualche chip di memoria che, da spento, potrebbe iniziare a dimenticare tutto.

Preferisco passare per “quello esagerato coi backup” piuttosto che per “quello che ha perso snowfan.it per risparmiare un disco”. Prevenire è meglio che curare… e molto meglio che piangere davanti a un prompt che dice: “drive not found” 😎🧊🛡️

Reminder that SMART is not magic, in my experience, disks are dead long before SMART stops reporting them as 'PASSED'.

I actually came across the perfect example today: Two disks in my backup server are having issues, one is clearly broken, the other gave 2 checksum errors.

Despite this, neither disk is 'failed' according to SMART, one has 456 offline uncorrectable errors / pending sectors, the other one is fine.

Don't rely on broken hardware to tell you that it's broken.

#storage #HDD #ZFS

the other disk's SMART info, a Seagate 4TB drive, showing 456 pending/offline uncorrectable sectors, however it is also marked as 'PASSED'. The disk has been used for 7 years (70k hours), and is currently 27C.

#HDD
Bon... le HDD 20 To de mon NAS n'a pas de réglage "silencieux". Tant pis.

À défaut, j'ai fait une défragmentation btrfs, ce qui a notablement réduit le nombre de petits "clac" dûs aux accès.
(d'autant que j'avais oublié de couper le CoW sur le répertoires des torrents, ce qui est crétin de ma part. Bon maintenant c'est coupé et défragmenté.)

I'm amazed by the speed which technology miniaturized active and passive electronics electronics.

My SBC is smaller than this 2.5" HDD! Amazing!!

The photograph shot in 85F warming light, shows a close-up of a hard disk drive (HDD) and a Raspberry Pi5 SBC in a box. The drive has a silver-colored metallic exterior with a black label adhered to its surface. On the label, there is printed text including "Micron" and "925745." Further text reads "Model: TH5300.73V02." More text includes "Made in Thailand" followed by a series of alphanumeric characters "S/N: K7R4644." Additional text is present, including "Firmware: 1.00." The text "DO NOT OPEN" appears, alongside "VOID WARRANTY IF REMOVED OR TAMPERED."
