Add a disk and migrate to raid 6.

I do not backup my media. When my zfs blows up, i need to start getting everything back again. I can live with it, it is nothing important. Thanks to sonarr/radarr etc, my media will recover itself over time anyway.

Important stuff is backed up at least twice locally and 1 times off side.

Remote storage (Pi at parents house with a big disk) and cron’ed btrfs send over ssh.

You can put a big hard drive in an external enclosure and use it for offline backups. There is no point in paying for cloud storage for something you can just download again if needed. Save the cloud storage for backing up non-replaceable data.

• automated scheduled copies
• syncing data to multiple machines
• scheduled copy to the cloud (not particularly frequent tho)

“Cloud” storage is indeed more expensive. But depending where you live, you count the electricity cost in, and you use the storage ‘only’ for backups. Maybe it makes more sense to pay for remote storage in a datacenter. Check out Hetzner Storage Box, it’s what I use.

If it’s still too expensive, maybe ask a friend or family member (maybe someone that uses your media) to setup a nas at their home for backup purpose. (I use this for my media)

Make sure you encrypt your backups if you use a remote location for your backups.

You have to decide what’s valuable for you. For me my media is, I can just download everything again, but the time I put in to have every movie the correct subtitles without ads, the correct posters, metadata etc. I value my time, I don’t want to do it again if I loose everything.

I feel like other people seeding is enough backup for me. I don’t backup my library at all.

I switched to catch and release 5 or 6 years ago and never looked back.

Data hoarding is a truly unique experience. Just my two cents

• raid is not a backup. Don’t use raid5 unless you’re using a filesystem like zfs that checksums your data. Raid5 is vulnerable to scenarios with a “write hole” that leads to bit rot.

• split up your dataset into smaller more manageable datasets so you can more easily back it up in different ways like external drives, cloud storage, etc. You can then limit the dataset size to never exceed the same of your backup target.

• snapshots, use them. Snapshots in your filesystem can make your backups more manageable by only sending the differential data as opposed to something like Rsync which may need to rsync an entire file.

I use ZFS and have found that compression with ZSTD works pretty well for getting extra use out of your disks but unless you have a lot of RAM and some special metadata NVME disks, don’t use reduplication as it will be a serious performance impact.

Now if you aren’t using a FOSS system like truenas and instead you’re using a system like a qnap off the shelf, the qnap hybrid backup and sync manager has a really elegant solution for doing policy based differential backups to back blaze b2 storage. Not only does this give you a copy of your data, you also get immutable points in time archives of your data.

Good luck in your data hoarding endeavors!

I think I’m bad at this

I have 4 main places I put stuff:

• My 2018 external 4tb WD HDD (filled up at around ¾)

• My 1tb laptop ssd

• My 256gb phone

• My laptop’s previous 2016 1tb hdd

On my external drive I put ~all of my data; my camera files, my screenshots, my phone’s app data (like expenses, call logs, contacts, sms, game data, fitness logs), documents etc.

On my laptop I have some stuff which I havent synced to my external drive for around 3 years (oops), but they probably arent the most important stuff.

On my phone I have a lot of important stuff, like around ⅔ of my total camera files (I try to keep the most important ones) and my app data.

On my old laptop’s 1tb hdd I keep movies/series and personal books/notebooks I have scanned. Those data dont exist anywhere else. If they get lost, especially the scanned books, it’s gonna be bad, because it both took a lot of time to scan them and I have thrown away many of the physical books.

If my external drive fails, around ¼ of the data it contains might be unrecoverable. They might not be the most important files, but still it’s gonna hurt a loooot.

I’m currently in the process of reorganizing my files on my laptop and my external drive for various reasons, some of them being 1) I will clear unnecessary/duplicate/temporary/etc files (which will reduce the used space) and 2) it will help me sync my files better.

In the near future I’ll probably buy 500gb lifetime on filen.io (cloud storage) to keep the most important stuff, possibly another 4tb drive to mirror my current one to this and ~hopefully I’ll make a nas next year to sync everything there.

It’s just to expensive for me tho🫤. Filen storage is around 100€, 4tb another 100€ (or I might buy 6tb at 150€) and the nas I want to make costs around 800€…

I want to make a nas to both store and stream stuff. Like a personal home server. I’m thinking of getting 2 12tb hdds and have one of two asynchronously mirror itself onto the other (that way one of the two will be off/disconnected ~most of the time, protecting it from wear and cyber attacks (not sure of the latter will work)).

Personally, I back up everything on my NAS except my movie library, because that is something I can relatively easily restore by just downloading buying it again, and because it’s of course the biggest chunk of data. For the other data, I’m using a very affordable Hetzner server auction system with a lot of disks in a striped array. This gives me the maximum amount of storage, and given that I can just create the backup again should the stripe fail, I’m not worried about redundancy on the backup itself.

I have a couple of external USB drives I bought on sale I backup my NAS to once a week. It’ll protect against drive failure at least. Almost got hit by ransomware a while back so I don’t keep anything on there without some backup.

RAID5 and unlimited downloads on my 1Gbps fibre. All I backup is my library metadata itself, using a 2N+C strategy.

Backblaze. $10 a month for infinite storage

My library is not nearly as large as yours but I’ve got the things that i can get back over time like movies and shows and stls and I’ve got the things that i can’t get back cached elsewhere.
