Config Backups

Config Backups lets you view, download, and compare configuration backups across your fleet. MaaS captures configuration backups nightly and on-demand. Open from TB Nodes > Config Backups.

Config Backups — 90-day backup history

---

Browsing Backups

• Hosts — click to select one or more devices (or All) to view their backup history.

• Backup table — every backup from the last 90 days with date, config name, hash, and size.

• Show unique configs only — hide duplicate entries (same config hash). On by default.

Comparing Backups

Select two backups and click Compare for a side-by-side diff.

Side-by-side diff

The diff is color-coded:

• Green — added

• Red — removed

• Purple — moved or reordered

Diff Controls

Control	What it does
Differences only	Hide unchanged lines.
Hide moved	Hide reordered sections, so you can focus on real changes.
Copy	Copy the full config from either side to your clipboard.
Export .diff	Download a standard unified diff file.
Fullscreen	Expand the diff to fill the screen.

Tips

• Use Compare with the same device across two dates to audit what actually changed on a specific unit.

• Use it across two devices to check for configuration drift in what should be identical setups.

• Differences only + Hide moved is usually the right combination for "what changed that matters".
