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!
Good on you to finally get into it, I switched to something systematic only very recently myself (previously it was "copy important stuff to an external HDD whenever I think of it").
The one thing that I learned (luckily the easy-ish way) is: test your backup. Yes, it's annoying, but since you rarely (ideally never!) will need to restore the backup it's incredibly easy to think that everything in your system is working and it either never having worked properly or it somehow started failing at some point.
A backup solution that has never been tested via a full restore of at least something has to be assumed to be broken.
Which reminds me: I have to set up the cron job to periodically test a percentage of all backed up data.
I decided to use Kopia, btw, but can't really say if that's well-suited for your goals.
