Hi everyone,
I'm trying to understand/document the inner workings of the OpenMediaVault Backup Plugin, specifically how the fsarchiver tool is used for restoring system backups.
I came across this helpful guide. Based on this, I've created a few diagrams representing different approaches for fsarchiver method, so that I understand what's beeing backup and what will be restored:
Option 1:
- Backup OS drive + OMV (config, installed plugins and their config).
- Mergerfs with its settings and drives content
Option 2:
- Backup OS drive + OMV (config, installed plugins and their config).
Option 3:
- Backup OS drive + OMV (config, installed plugins and their config).
- Backup Docker containers, their settings and volumes
Option 4:
- Actually no diagram, but: backup captures the entire system (Options 1 thru 3)
Option 5:
- None of the above is right
Can someone with expertise in the OMV Backup Plugin confirm which of these architectures represent the approach used by fsarchiver for restoring backups?
Thanks in advance for your help!
