I plan to upgrade my server to an 8 core 16 thread processor I know nothing huge but its double what I currently run. I am also adding 4x the ram bumping it up to 16GB and running a 2TB NVME. AMD with GPU built in it is fairly low powered all in all and seems to offer a pretty good bang for the buck.
Couple of questions for those who may have had more travel time in Linux than I have had.
What would be the best route to take software wise to run say 4 Virtual Machines from this server? Proxmox, VMware, Docker, Maybe Cloudmin?
What would be the best avenue to backup my current server image so I don’t lose any of my data using Debian 10 so it can run as one of these VM’s?
Currently my image has been backed up bare metal from an old server so I always get errors about the disk UID not matching every time I do updates as well as Grub errors it would be nice not to have to see this although it doesn’t seem to affect anything when making my image.
I am curious on the methods, OS, and software you guys are having luck with or even maybe struggling with I am willing to invest the time but I kind of want to get some feedback from more seasoned users so I can better choose the methods and software to use. I currently have one virtualmin license at the moment for 10 domains I believe but likely only a single server if memory serves me right so I may have to purchase more as needed. Eventually as time goes on I plan to go much bigger like EPYC territory but I just can’t quite justify the expense at the moment.
I’d like to have a rather easy method of backing up my servers incrementally thus I feel the VM type server just makes way more sense to me as time goes on I neglect bare metal backups due to their tedious nature (only doing them bare minimal once a month average). From what I’ve seen in the land of backups VM’s are king.
Would love to hear some thoughts and opinions even if contrarian.
