I have a home server that I’m using and hosting files on it. I’m worried about it breaking and loosing access to the files. So what method do you use to backup everything?

Backblaze on a B2 account. 0.005$ per gb. You pay for the storage you use. You pay for when you need to download your backup.
On my truenas server, it’s easy as pie to setup and easy as 🥧 to restore a backup when needed.
I’ll add to this that restic works amazingly with Backblaze.
I also recommend B2, it’s an S3 compatible service so any backup software/scripts/plugins that work with S3 should work with Backblaze.
B2 is awesome. I have Duplicati set up on OpenMediaVault to backup my OS nightly to B2 (as well as a local copy to the HDD).
Maybe I’m stupid, but what is B2? A Backblaze product?
Yes it’s their cloud storage.
I didn’t realize they did anything other than that!
I think they had some form of cloud computing at some point but they now focus on B2 and some backup tools that utilize B2.

On hope
The “small to medium business” route I see!
And using the fact that raid is a backup!
This guy is rawdogging his RPi, just like me
Me too! Actual servers are docker-compose which is on git but the data…yeah that’s on hope hahaha
This is the way.
You guys back up your server?
If your data is replaceable, there’s not much point unless it’s a long wait or high cost to get it back. It’s why I don’t have many backups.
In the 20 years that I’ve been running a home server I’ve never had anything more than a failed disk in the array which didn’t cause any data loss.
I do have backups since it’s a good practice and also because it familiarizes me with the software and processes as they change and update so my skillset is always fresh for work purposes.

ITT: lots of the usual paranoid overkill. If you do
rsyncwith the--backupswitch to a remote box or a VPS, that will cover all bases in the real world. The probability of losing anything is close to 0.The more serious risk is discovering that something broke 3 weeks ago and the backups were not happening. So you need to make sure you are getting some kind of notification when the script completes successfully.
While I don’t agree that using something like restic is overkill you are very right that backup process monitoring is very overlooked. And recovering with the backup system of your choice is too.
I let my jenkins run the backup jobs as I have it running anyways for development tasks. When a job fails it notifies me immediately via email and I can also manually check in the web ui how the backup went.

3-2-1
Three copies. The data on your server.
-
Buy a giant external drive and back up to that.
-
Off site. Backblaze is very nice
How to get your data around? Free file sync is nice.
Veeeam community version may help you too
I’m not sure how you understand the 3-2-1 rule given how you explained it, even though you’re stating the right stuff (I’m confused about your numbered list…) so just for reference for people reading that, it means that your backups need to be on:
- 3 copies
- 2 mediums
- 1 offsite location

Proxmox Backup Server. It’s life-changing. I back up every night and I can’t tell you the number of times I’ve completely messed something up only to revert it in a matter of minutes to the nightly backup. You need a separate machine running it–something that kept me from doing it for the longest time–but it is 100% worth it.
I back that up to Backblaze B2 (using Duplicati currently, but I’m going to switch to Kopia), but thankfully I haven’t had to use that, yet.
PBS backs up the host as well, right? Shame Veeam won’t add Proxmox support. I really only backup my VMs and some basic configs
Veeam has been pretty good for my HyperV VMs, but I do wish I could find something a bit better. I’ve been hearing a lot about Proxmox lately. I wonder if it’s worth switching to. I’m a MS guy myself so I just used what I know.
Veeam can’t backup Proxmox on hypervisor level, only HyperV and VMWare
PBS only backs up the VMs and containers, not the host. That being said, the Proxmox host is super-easy to install and the VMs and containers all carry over, even if you, for example, botch an upgrade (ask me how I know…)
Then what’s the purpose over just setting up the built in snapshot backup tool, that unlike PBS can natively back up onto an SMB network share?
I’m not super familiar with how snapshots work, but that seems like a good solution. As I remember, what pushed me to PBS was the ability to make incremental backups to keep them from eating up storage space, which I’m not sure is possible with just the snapshots in Proxmox. I could be wrong, though.
You are right about the snapshots yeah. The built in backup doesn’t seem to do incremental backups.
cronjobs with rsync to a Synology NAS and then to Synology’s cloud backup.
I am lucky enough to have a second physical location to store a second computer, with effectively free internet access (as long as the data volume is low, under about 1TB/month.)
I use the ZFS file system for my storage pool, so backups are as easy as a few commands in a script triggered every few hours, that takes a ZFS snapshot and tosses it to my second computer via SSH.
My server runs Plex and has almost 50 TB of video on it. After looking at all the commercial backup options I gave up on backing up that part of the data. :-(
I do backup my personal data, which is less than a terrabyte at this point. I worked out an arrangement with a friend who also runs a server. We each have a drive in the other’s server that we use for backup. Every night cron runs a simple rsync script to do an incremental backup of everything new to the other machine.
This approach cost nothing beyond getting the drives. And we will still have our data even if one of the servers is physically destroyed and unrecoverable.
I also have a decent amount of video data for Plex (not nearly 50TB, but more than I want I pay to backup). I figure if worst comes to worst I can rip DVD/BluRays again (though I’d rather not) so I only backup file storage from my NAS that my laptops and desktop backup to. It’s just not worth the cost to backup data that’s fairly easy to replace.
Yeah, that was where I finally came out too. I still own the discs. My only worry is that some of my collection is beginning to age. I’ve had a few DVDs that were no longer readable.
Oh that whith the friend’s server is a good idea. Mutual benefit at little extra cost
It’s the only “no cost” option I know of that provides an off-site backup. And once it occurred to me, it was really easy to set up.
Autorestic, nice wrapper for restic.
Data goes from one server to second server, and vice versa (different provider, different geolocation). And to backblaze B2 - as far as I know cheapest s3-like storage
Wasabi might also be worth mentioning, a while back I compared S3-compatible storage providers and found them to be cheaper for volumes >1TB. They now seem to be slightly more expensive (5.99$ vs. 5$), but they don’t charge for download traffic.
So what method do you use to backup everything?
Depends on what OS that server is running. Windows, Unraid, Linux, NAS (like Synology or QNAP), etc.
There are a bazillion different ways to back up your data but it almost always starts with “how is your data being hosted/served?”
I have everything in its own VM, and Proxmox has a pretty awesome built in backup feature. Three different backups (one night is to my NAS, next night to an on-site external, next night to an external that’s swapped out with one at work - weekly). I don’t backup the Proxmox host because reinstalling it should it die completely is not a big deal. The VM’s are the important part.
I have a mini PC I use to spot check VM backups once a month (full restore on its own network, check its working, delete the VM after).
My Plex NAS only backs up the movies I really care about (everything else I can “re-rip from my DVD collection”).
