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.

A huge tape archive in a mountain. It's pretty standard for geophysical data. I have some (encrypted) personal stuff on a few tapes there.

I use rsync.net

It's not the lowest price, but I like the flexibility of access.

For instance, I was able to run rclone on their servers to do a direct copy from OneDrive to rsync.net, 400Gb without having to go through my connection.

I can mount backups with sshfs if I want to, including the daily zfs snapshots.

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.

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 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.

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.

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 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.

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.

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 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!).

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.

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!

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.

My automated workflow is to package up backup sources into tars (uncompressed), and encrypt with gpg, then ship the tar.gpg off to backblaze b2 and S3 with rclone. I don't trust cloud providers so I use two just in case. I've not really been in the need for full system backups going off site, rather just the things I'd be severely hurting for if my home exploded.

But to your main questions, I like gpg because you have good options for encrypting things safely within bash/ash/sh scripting, and the encryption itself is considered strong.

And, I really like rclone because it covers the main cloud providers and wrangles everything down to an rsync-like experience which also pretty tidy for shell scripting.
