# 001 — Why backing up an agent is so hard

## Research notes
|
||||||
|
|
||||||

### Real filesystem changes after one week of work on a Linux agent
|
||||||
|
|
||||||
|
```
|
||||||
|
504.6M ./usr
|
||||||
|
43.3M ./var
|
||||||
|
448.9M ./root
|
||||||
|
54.0K ./etc
|
||||||
|
996.8M .
|
||||||
|
```
|
||||||
|
|
||||||
|
Most users only back up the home directory (`/root` = 448.9M). But over half the changes live outside it — `/usr` (504.6M) and `/var` (43.3M) contain installed packages, pip/npm global installs, database files, logs, and system configs. A naive home-dir-only backup misses 55% of what changed.
|
||||||
|
|
||||||
|
At restore time, you get your config back but the agent won't run — missing dependencies, missing system packages, missing database files.
|
||||||
|
|
||||||
|
### What this means for the post
|
||||||
|
|
||||||
|
- Agent environments are not just config files — they're full Linux systems with packages, services, and state scattered everywhere
|
||||||
|
- "Backup your home directory" is dangerously incomplete advice for AI agents
|
||||||
|
- Derez.ai's full-disk snapshot approach is the right solution
|
||||||
|
- This is a strong selling point: the agent works after restore, not just the config
|
||||||
|
|
||||||
|
### Next data points
|
||||||
|
|
||||||
|
Oliver will do two more memory analysis snapshots after running the speed-run setups (Odoo + Cold Email). Those will show how much additional state those integrations add.
|
||||||
|
|
||||||
|
### Outline
|
||||||
|
|
||||||
|
1. The sprawl problem — why agents are harder to back up than a standard server
|
||||||
|
*Include the filesystem analysis table*
|
||||||
|
2. What a real agent backup needs to capture
|
||||||
|
3. How Borg/deduplicated snapshots solve it
|
||||||
|
4. How Derez.ai does it automatically (one-click restore)
|
||||||
|
5. Best practices for users
|
||||||
|
6. Better save than sorry — the selling point
|
