I’m not quite sure what “truenas” is? All of my stuff is individually installed, I decided a long time ago to split it up onto VMs that each perform an specific task. I have a main file server that runs zfs, then two servers to run the redundant VMs. There’s not really anything difficult about backups, I just add a cron job to run a script once a day and never touch it again, so I have backups of each VM but then the backups of the main servers includes the VM image files so each VM gets backed up twice. There’s a lot of info there but the backups of all the critical stuff only use about 6TB (I could actually cut that in half if I got rid of the backups from older machines).
So lets say I put in the time to learn how docker works, and then put in a lot more time converting all of my existing systems over to docker images… What exactly what I get out of all that effort? The thing that nobody’s been able to sell me on so far is that I don’t see how docker is going to make anything any easier, it just seems like it’s a “different” way to do things but nothing more.
