Follow the storage rules:
3-2-1
3 or more copies
2 or more different medias
1 or more off site

There is a 3-2-1 tactic for backups, which should be pretty safe. Lots of articles if you search for it. Basically I backup all my data to two SSDs and one HDD. And once more to cloud, which is iCloud in my case.

I use Google drive to backup my pics and memes because I don't have enough to warrant getting anything bigger. I have the $2/month Google One subscription because the free one was barely too small. I can't get rid of memes tho.

NAS + Syncthing

I have a Synology server. I have an external drive. I have an extra 2TB drive on my PC. I have two large storage thumb drives. I have a Google photos account. I have an Instagram, I have a pixelfed account. I have a drop box account. I have a mega account. They all hold my photos. Do you want more? 😂

Backup to Synology Photos / Drive which backs up to AWS Glacier

I have a server in the garage with a big RAID array, and I run a Nephele WebDAV server on it. All my PCs, and my family’s PCs back up to it every 3 days.

It also streams all my movies and TV shows on a Jellyfin server.

Also, to be extra cautious, I have a server at my in laws’ house with a 20TB hard drive that I periodically sync that RAID array to.

(Full disclosure: I am the author of Nephele.)

I use duplicity to do incremental backups that are encrypted with GPG keys. I then back everything up onto a second hard drive. And then I make a second copy that gets uploaded to backblaze B2. In theory it's all encrypted and safe there. I then have a copy of my encryption keys on a CD, thumb drive, as well as a printed out copy that is stored in a safety deposit box.

I have my own script that I want for duplicity, but I've heard duplicati is it GUI that's easy to use, but I have not used it.

i fire up syncthing every once in a while, mainly because of pictures of my cat. i store it all on my main PC, and am planning to implement my NAS as well soon.

I wouldn't necessarily trust a cloud so I would encrypt my files before uploading and wouldn't use the cloud as my only solution. Because they guarantee for nothing and could just delete your account or their service. But it can expand your backup with another layer.

(Haven't found my perfect solution, just some thoughts)

Both.

Though i don't really care if the HDD is external or internal, just that it stores data physically.

When I reached Google Photos max capacity, I invested in a good 4 bay Synology NAS with 16TB. I left the old photos and documents in Google Cloud but all new ones go to the NAS.

I'm really happy with the NAS. I'm aware I could have saved money with a homebuilt one, but I wasn't botheres tinkering.

Master copy on my desktop

At midnight, my cron job kicks in and mirrors it to

• hard drive
• makes a backup to another machine via restic
• makes another restic backup to backblaze

Apple ecosystem so: iPhone > iCloud Photo Library (imported all digital photos over the years through iPhoto, later Photos) > Mac Photos app (set to download all originals) > Time Machine backup on my Synology NAS with redundancy

And because I’m a belt and suspenders kind of guy:

iPhone > Synology Photos backup > Synology C2 cloud backup

Syncthing

One hard drive on site. One hard drive off site. Rotate regularly.

Always do both. Ideally have three copies of your data at all times. For the most important stuff, I also sent a drive to a family member in a different part of the county in case of natural disaster.

It's a bit overkill but I use Google Photos + iCloud + Local backup to an external HD + Backblaze cloud backup of said backup drive.

I use Nextcloud to sync them from my phone/laptop/pc to my server then sync to my NAS, then monthly backup to a hard drive, which i rotate out off-site. In progress switching this to another NAS I store off site.

I use: 1 copy in my primary SSD on my laptop 1 copy in my secondary SSD on same laptop, which autosyncs to: 1 copy in OneDrive family plan 1 copy on an external SSD

Kind of based on the 3-2-1 method.

I know that I'm gonna get hate for this but... My phone is spoofed to appear as a pixel 5, so I have unlimited Google drive storage... I would setup next cloud, if I had the hardware to...

Phone, PC, external SSD, iCloud All synced once a week or month or whatever

2TB Google Drive, ~$100/yr.

VEEAM makes a local backup every night, but all my Windows libraries are mapped to a Google drive. Anything saved there automatically syncs to the cloud.

Everything gets backed up to a Nextcloud instance running on my main Proxmox hypervisor. Every 24 hours, each VM gets backed up to my NAS. In addition, my Nextcloud VM runs a script every night to upload its entire database to Backblaze.

I email them to myself
