Selfhosted

My dad and I each have Synology NAS. We do a hyper sync backup from one to the other. I back up to his and vice versa. I also use syncthing to backup my plex media so he can mount it locally on his plex server.

RClone to a cloud storage (hetzner in my case). Rclone is easy to configure and offers full encryption, even for the file names.

As the data is only uploaded once, a daily backup uploads only the added or changed files.

Just as a side note: make sure you can retrieve your data even in case your main system fails. Make sure you have all the passwords/crypto keys available.

I have a rpi4 awith an external hdd at my parents house, which I connect via a wireguard vpn, mount and decrypt the external hdd and then it triggers a restic backup to a restic-rest server as append only.

The whole thing is done via a python script

I chose the rest-server because it allows "append only", so the data can't be deleted easily from my side of the vpn.

I just rsync it once in a while to a home server running in my dad’s house. I want it done manually in a “pull” direction rather than a “push” in case I ever get hit with ransomware.

Put brand new drive into system, begin clone

When clone is done, pull drive out and place in a cardboard box

Take that box to my off-site storage (neighbors house) and bury it

(In truth I couldn't afford to get to the 1 off-site in time and have potentially tragically lost almost 4TB of data that, while replacable, will take time because I don't fucking remember what I even had lol. Gonna take the drives to a specialist tho cuz I think the plates are fine and it's the actual reading mechanism that's busted)

For storing the backups, I use a storage VPS. I got one from HostHatch a few years ago during Black Friday sales, with 10TB space for $10/month. Hetzner have good deals with their storage boxes, too - they offer 5TB space for $13/month if you're in the USA (you need to add VAT if you're in Europe).

A good rule of thumb is to never pay more than $5/TB/month, and during Black Friday it's closer to $2/TB/month. The LowEndTalk forum has the best Black Friday deals.

I use Borgbackup for backups, and Borgmatic to handle scheduling them. Borgbackup is a fantastic piece of software.

Borgmatic has an "append only" mode which lets you configure particular SSH keys to only be able to add data to the backup, not delete it. Even if someone/something (ransomware, malicious users, etc) gains access to your system and tries to delete the backups, they can't. Essentially, this is protection against ransomware.

This is a very common issue with other backup solutions - the client has full access to the backup, so malware on the client system could potentially delete all the backups.

I have two backup copies of most things. One copy on my home server and one copy on my storage VPS. If you do do multiple backups, Borgbackup recommend doing two separate backups rather than doing one then rsyncing it to another server.

I have two large (8 Bay) Synology NAS. They backup certain data between each other and replicate internally and push to Back blaze. $6/mo.

Right now I sneaker net it. I stash a luks encrypted drive in my locker at work and bring it home once a week or so to update the backup.

At some point I'm going to set up a RPI at a friend's house, but that's down the road a bit.

Rclone to dropbox. ( was cheapest for 2tb at the time )

Idrive has built in local encryption you can enable.

I use Proxmox PBS for all my backups. Datastore is on my file server at home. I sync the datastore daily to a little NAS at a family members house and to a super cheap storage VPS on the other side of the country. I also do a manual sync to an external drive that keep offline at home.

Any super important documents such as tax records, health related files, backup of the data volume from vaultwarden, or anything related to wills & estates get backed up as well to 2 USB thumb drives that are LUKS encrypted. I keep 1 in my go bag and another is hidden somewhere.... Thumb drives get updated once a month, or sooner if anything major changes.

If you are gonna go for TrueNAS, try Storj with TrueNAS Cloud task. TrueNAS made a partnership with Storj and the price is very good. https://www.truenas.com/truecloud-backup/

TlDr; The data is encrypted with restic and sent to Storj S3 storage that is further fragmenting it (and encrypting it too - so double encryption) into multiple pieces (with redundancy) and storing on other peoples TrueNASes (you can also provide your unused space btw and gain some small money back).

I am in process of setting this up (already run a working test backup) and I didn't find anything that's better than this integrated solution. Very cool!

I use Linux, so encryption is easy with LUKS, and Free File Sync to drives that rotate to a safety deposit box at the bank for catastrophic event, such as a house fire. Usually anything from the last few months are still on my mobile devices.

If you use ZFS this becomes easy, because you can do incremental backups at the block level.

I have my home lab server and do snapshots and sends to a server at my fathers house. Then I also have an external drive that I snapshot to as well.

I assume daily would be a bit much considering it's gonna be a few TB worth of HDDs which aren't exactly fast

What is the concern here?

I have an external storage unit a couple kilometers away and two 8TB hard drives with luks+btrfs. One of them is always in the box and after taking backups, when I feel like it, I detach the drive and bike to the box to switch. I'm currently researching btrbk for updating the backup drive on my pc automatically, it's pretty manual atm. For most scenarios the automatic btrfs snapshots on my main disks are going to be enough anyway.

I got my parents to get a NAS box, stuck it in their basement. They need to back up their stuff anyway. I put in 2 18 TB drives (mirrored BTRFS raid1) from server part deals (peeps have said that site has jacked their prices, look for alts). They only need like 4 TB at most. I made a backup samba share for myself. It’s the cheapest symbology box possible, their software to make a samba share with a quota.

I then set up a wireguard connection on an RPi, taped that to the NAS, and wireguard to the local network with a batch script. Mount the samba share and then use restic to back up my data. It works great. Restic is encrypted, I don’t have to pay for storage monthly, their electricity is cheap af, they have backups, I keep tabs on it, everyone wins.

Next step is to go the opposite way for them, but no rush on that goal, I don’t think their basement would get totaled in a fire and I don’t think their house (other than the basement) would get totaled in a flood.

If you don’t have a friend or relative to do a box-at-their-house (peeps might be enticed with reciprocal backups), restic still fits the bill. Destination is encrypted, has simple commands to check data for validity.

Rclone crypt is not good enough. Too many issues (path length limits, password “obscured” but otherwise there, file structure preserved even if names are encrypted). On a VPS I use rclone to be a pass-through for restic to backup a small amount of data to a goog drive. Works great. Just don’t fuck with the rclone crypt for major stuff.

Lastly I do use rclone crypt to upload a copy of the restic binary to the destination, as the crypt means the binary can’t be fucked with and the binary there means that is all you need to recover the data (in addition to the restic password you stored safely!).

Look into storj and tardigrade. It's a crypto thing, but don't get scared. You back up to S3 compatible endpoints and it's super cheap (and pay with USD credit card)

I use LUKS and backup to a usb-drive that I have at home. I rsync those backups to my work once a week. Not everyone can backup to their office, but as others have said, backing up to a friend/family member's house is doable. The nice thing about rsync is that you can limit the bandwidth, so that even though it takes longer, it doesn't saturate their internet connection.

you can rent a vps and set up encrypted backups

I spend my days working on a MacBook, and have several old external USB drives duplicating my important files, live, off my server (Unraid) via Resilio to my MacBook (yes I know syncthing exists, but Resilio is easier). My off-site backups are to a Hetzner Storage Box using Duplicacy which is amazing and supports encrypted snapshots (a cheap GUI alternative to Borgbackup).

So for me, Resilio and Duplicacy.
