I have a confession to make.
I've been working in IT for about 6/7 years now and I've been selfhosting for about 5. And in all this time, in my work environment or at home, I've never bothered about backups. I know they are essential for every IT network, but I never cared to learn it. Just a few copies of some harddisks here and there and that is actually all I know. I've tried a few times, but I've often thought the learning curve to steep, or the commandline gave me some errors I didn't want to troubleshoot.
It is time to make a change. I'm looking for an easy to learn backup solution for my home network. I'm running a Proxmox server with about 8 VMs on it, including a NAS full of photos and a mediaserver with lots of movies and shows. It has 2x 8TB disks in a RAID1 set. Next to that I've got 2 windows laptops and a linux desktop.
What could be a good backup solution that is also easy to learn?
I've tried Borg, but I couldn't figure out all the commandline options. I'm leaning towards Proxmox Backup Server, but I don't know if it works well with something other than my Proxmox server. I've also thought about Veeam since I encounter it sometimes at work, but the free version supports only up to 10 devices.
My plan now is to create 2 backup servers, 1 onsite, running on something like a raspberry pi or an HP elitedesk. The other would be an HP microserver N40L, which I can store offsite.
What could be the perfect backup solution for me?
EDIT:
After a few replies I feel the need to mention that I'm looking for a free and centrally managed option. Thanks!
I guess I just want to make sure the pictures are safe. Next to that I'll backup my /home/user folder, but next to that it's not that hard to rebuild my VMs.
Simplest way there is to keep them on a dedicated storage system that you don't even need to access directly for the most part. If there's one thing I learned over many years playing with servers is that the end user/admin is more a hazard to your data than the system failing ever could be. A raid1 will automatically protect you if one of the hardrives happens to die without thinking about it, but will just as quickly delete everything on both drives if you run the wrong command.
My nightmare example from personal experience, installing a new pair of drives with the intent to migrate to them.
Install drive 'b', rsync -a dive 'a' to 'b' Wipe 'a' for storge/disposal, Install new drive 'a' to original slot of 'a' Start second rsync intended to be 'b' to 'a' but forget to change drives and instead sync the new blank 'a' to ' b' with the only copy of your data...
Fortunately I managed to get most everything back with some data recovery tools, but that second after pressing enter and watching it all go away was wrenching. Since then I've become a lot more aware of having a certain level of protection against human error.
