Honestly I tried searching here, but either I get confused or I cannot tell is the solution will fit my needs
I have
[windows]
my main PC
work laptop
a second home machine that does some tasks that I don't want on the main PC (like housing all the backups)
personal laptop
a bunch of loose hard drives, both SSD and HDD with data that I might want in the future(grandparents disks full of photos type stuff)
a PC set up as a DVR for a bunch of security cameras(not wanting to save the footage, just an easy restore if something breaks and a reinstall is needed)
Linux
a couple of PCs used for Minecraft servers
a PC set up for home assistant
a couple of netbooks, some have software for 3d printers, CNC machines, Laser engravers, etc
a whole load of raspberry pi's with various weird stuff
a stack of DVDs and CDs that I'd like to have backup copied in case of physical damage
right now I have some backups of some machines, but I have not been able to get everything backed up
my plan
take my recently purchased 16tb drive and dump everything on that, then get another drive to copy the first (or expand)....THEN set up a backup physically somewhere else
what are my options? I've cloned drives with FileZilla, but only on a "copy this HDD to a SSD to improve old machine", not for backups
I tried to get windows backup to try to backup my main PC to the secondary PC, but it fails more often than it works
getting Linux and windows to play nicely together seems like black magic. more comfortable in windows than Linux
tutorials, software options desired, dedicated NAS hardware solutions or cloud are not
