Thx for the reply and the porided sugestions. I will check them out. "the average family probably has less than 2TB data" Backups here are 23TB, reduced to 7.

Thx for the reply and the porided sugestions. I will check them out. "the average family probably has less than 2TB data" Backups here are 23TB, reduced to 7.5 after dedup. Maybe we're a bit more into tech than the average family, but 2TB does not sound reasonably if you have some retention. We do have the O365 family sub. The Onedrive portion is used sparingly, and I would never count on it for backups. I've always had something NAS like. Had Microsoft's WHS for a while on a spare PC until that was discontinued, now on my second Synology. It's not perfect but saved the day several times. Putting in the usb after a disk replacement and restoring to yesterday's point in time quickly is vital as disk crahes tend to happen at the least convenient moment.

> The Onedrive portion is used sparingly, and I would never count on it for backups. Depends how you use it I guess. Mine works as a backup target for Arq backup, and holds encrypted, versioned client backups. > Backups here are 23TB, reduced to 7.5 after dedup. How much of that data is stuff you can easily download again ? While we’re nowhere near professional photographs, we do take around 10k photos every year, and our family photo library stretches back almost two decades, and yet our family photo backup is “only” around 3TB, and 1.3TB compressed and deduplicated (quite a few RAW images there). Yearly growth is below 100GB, I know because I make yearly M-disc archives of the previous years photos, and they fit on a 100GB BD-XL. Besides the photo backup, our documents, school work, music collection (ripped from CDs), purchased ebooks and more is less than 500GB (compressed, deduplicated) I could probably save a couple hundred GB by leaving out music and ebooks, as the music is still on the CDs, and ebooks can (probably) be downloaded again, or they’re outdated enough that it doesn’t matter. The absolute minimum would be our photos, which naturally are irreplaceable. Even documents will be outdated rather fast, and are mostly only kept for nostalgia.
