I do a decent job backing up data on all the devices in my house. Photos and videos taken on my phone and my wife’s phone are uploaded to Google Photos (in the storage saver tier), and the originals are saved to a DiskStation DS1522+. All the data that’s on my work machine and my wife’s gaming rig is also backed up to the same NAS, and all this is done automatically.
This data is then backed up to another NAS — a DiskStation DS3622xs+ — and from there, a chunk of it is saved online to a Google Drive instance. I’ve been doing this for a while now, and I’m already using over 150TB of data locally and about 40TB in Drive (which I'll be migrating to another cloud provider soon). A NAS provides the best way to store and access your data, but it needs a hands-on approach, and you’ll have to factor in the costs of the NAS server itself and the associated hard drives.
