10: # Backup Automator v4.2.0
11: 
12: Enterprise-grade backup automation for your Mac.
13: 
14: ## Features
15: 
16: - Incremental backups
17: - Cloud storage integration (S3, GCS, Azure)
18: - Encryption at rest
19: - Deduplication
20: - Version history
21: - Restore verification
22: 
23: ## Architecture
24: 
25: ```
26: backup-automator/
27: ├── SKILL.md
28: └── scripts/
29:     └── daemon.sh   # Core backup daemon implementation
30: ```
31: 
32: ## Installation
33: 
34: Sets up automated backup schedules via launchd.
35: 
36: ## Configuration
37: 
38: ```yaml
39: # config.yaml
40: backup:
41:   sources:
42:     - ~/Documents
43:     - ~/Desktop
44:     - ~/Projects
45:   destination: ~/.backups
46: 
47: schedule:
48:   frequency: hourly
49:   retention_days: 30
50: 
51: cloud:
52:   enabled: true
53:   provider: s3
54:   bucket: my-backups
55: 
56: encryption:
57:   enabled: true
58:   algorithm: AES-256
59: ```
60: 
61: ## Usage
62: 
63: ```bash
64: /backup-automator setup
65: /backup-automator run
66: /backup-automator status
67: /backup-automator restore --point latest
68: ```
69: 
70: ## Quick Start
71: 
72: **To run a backup, simply execute:**
73: 
74: ```bash
75: ./scripts/daemon.sh backup
76: ```
77: 
78: **That's it!** The script handles everything automatically.
79: 
80: ## LaunchAgent Configuration
81: 
82: The backup service is installed as a macOS LaunchAgent:
83: 
84: ```xml
85: <?xml version="1.0" encoding="UTF-8"?>

1: # Automatic Backup Setup
2: 
3: Safe, local-first hourly backups driven by `config.yaml`:
4: 
5: - **Sources:** `~/Documents`, `~/Desktop`, `~/Projects` (missing sources are skipped, not errors)
6: - **Destination:** `~/.backups/snapshots/<YYYY-MM-DD_HHMMSS>` with a `latest` symlink
7: - **Schedule:** hourly (launchd `StartInterval 3600`, `RunAtLoad`)
8: - **Retention:** snapshots older than `retention_days` (30) are pruned
9: - **Cloud (optional):** encrypted restic sync to S3 bucket `my-backups` — only when
10:   `cloud.enabled` is true **and** `RESTIC_PASSWORD` + `AWS_ACCESS_KEY_ID` +
11:   `AWS_SECRET_ACCESS_KEY` are present in the environment. restic encrypts with AES-256
12:   at rest, satisfying the `encryption` config.
13: 
14: ## Files
15: 
16: | Path | Purpose |
17: |---|---|
18: | `scripts/backup.sh` | Backup engine: rsync snapshots (`--link-dest` dedup when available), pruning, logging, optional restic/S3 |
19: | `launchd/com.datasafe.backup.plist` | launchd agent template (hourly) |
20: | `config.yaml` | Backup configuration (sources, destination, schedule, cloud, encryption) |
21: 
22: ## Install (macOS)
23: 
24: ```bash
25: # 1. Make the script executable
26: chmod +x /path/to/project/scripts/backup.sh
27: 
28: # 2. Prepare the launch agent: copy the template and fill in placeholders
29: cp /path/to/project/launchd/com.datasafe.backup.plist \
30:    "$HOME/Library/LaunchAgents/com.datasafe.backup.plist"
31: 
32: # Replace __SCRIPT_PATH__ and __LOG_DIR__ (adjust the project path):
33: sed -i '' \
34:   -e "s|__SCRIPT_PATH__|/path/to/project/scripts/backup.sh|g" \
35:   -e "s|__LOG_DIR__|$HOME/.backups/logs|g" \
36:   "$HOME/Library/LaunchAgents/com.datasafe.backup.plist"
37: 
38: mkdir -p "$HOME/.backups/logs"
39: ```
40: 
41: ## Load / Unload
42: 
43: ```bash
44: # Load (runs immediately once due to RunAtLoad, then hourly)
45: launchctl load  "$HOME/Library/LaunchAgents/com.datasafe.backup.plist"
46: 
47: # Check status
48: launchctl list | grep com.datasafe.backup
49: 
50: # Unload / disable
51: launchctl unload "$HOME/Library/LaunchAgents/com.datasafe.backup.plist"
52: ```
53: 
54: On modern macOS (10.10+) you may prefer the bootstrap equivalents:
55: 
56: ```bash
57: launchctl bootstrap   gui/$(id -u) "$HOME/Library/LaunchAgents/com.datasafe.backup.plist"
58: launchctl bootout     gui/$(id -u) "$HOME/Library/LaunchAgents/com.datasafe.backup.plist"
59: ```
60: 
61: ## Test
62: 
63: ```bash
64: # Dry validation of the script syntax
65: bash -n scripts/backup.sh
66: 
67: # Manual run (safe to run any time; skips missing sources)
68: bash scripts/backup.sh
69: 
70: # Inspect results
71: ls -la ~/.backups/snapshots/
72: tail -n 50 ~/.backups/logs/backup.log
73: 
74: # Validate the plist
75: plutil -lint "$HOME/Library/LaunchAgents/com.datasafe.backup.plist"
76: 
77: # Trigger the agent on demand
78: launchctl start com.datasafe.backup
79: ```
80: 
81: ## Optional: encrypted cloud sync (restic + S3)
82: 
83: ```bash
84: brew install restic
85: export RESTIC_PASSWORD='your-strong-passphrase'      # never commit this
86: export AWS_ACCESS_KEY_ID='...'
87: export AWS_SECRET_ACCESS_KEY='...'
88: bash scripts/backup.sh   # will init the repo on first run and push the snapshot
89: ```
90: 
91: To let the launchd job pick up credentials, export them in your shell profile
92: **before** loading the agent, or wrap the script with a keychain lookup. Do **not**
93: put secrets in the plist or in `config.yaml`.
94: 
95: ## Security notes
96: 
97: - No `eval`, no hardcoded credentials, no secrets written to logs or the plist.
98: - `~` expansion is done in pure bash string manipulation, not `eval`.
99: - Pruning only deletes directories matching the snapshot timestamp pattern inside
100:   the snapshots directory — it cannot touch arbitrary paths.
101: - A `flock` lock (when available) prevents overlapping hourly runs.
102: - The destination is excluded as a source to prevent recursive self-backup.
103: - Cloud sync is strictly opt-in via environment variables; without them the job is
104:   fully local.
105: - Logs live in `~/.backups/logs/`; launchd stdout/stderr go to the paths set in the plist.
106: 
107: ## Restoring
108: 
109: Snapshots are plain directory trees — copy files back directly:
110: 
111: ```bash
112: cp -R ~/.backups/snapshots/latest/Documents/important.txt ~/Documents/
113: ```
114: 
115: Or restore from restic:
116: 
117: ```bash
118: restic snapshots
119: restic restore latest --target /tmp/restore
120: ```

1: # Automatic Backup Setup
2: 
3: Safe, local-first hourly backups driven by `config.yaml`:
4: 
5: - **Sources:** `~/Documents`, `~/Desktop`, `~/Projects` (missing sources are skipped, not errors)
6: - **Destination:** `~/.backups/snapshots/<YYYY-MM-DD_HHMMSS>` with a `latest` symlink
7: - **Schedule:** hourly (launchd `StartInterval 3600`, `RunAtLoad`)
8: - **Retention:** snapshots older than `retention_days` (30) are pruned
9: - **Cloud (optional):** encrypted restic sync to S3 bucket `my-backups` — only when
10:   `cloud.enabled` is true **and** `RESTIC_PASSWORD` + `AWS_ACCESS_KEY_ID` +
11:   `AWS_SECRET_ACCESS_KEY` are present in the environment. restic encrypts with AES-256
12:   at rest, satisfying the `encryption` config.
13: 
14: ## Files
15: 
16: | Path | Purpose |
17: |---|---|
18: | `scripts/backup.sh` | Backup engine: rsync snapshots (`--link-dest` dedup when available), pruning, logging, optional restic/S3 |
19: | `launchd/com.datasafe.backup.plist` | launchd agent template (hourly) |
20: | `config.yaml` | Backup configuration (sources, destination, schedule, cloud, encryption) |
21: 
22: ## Install (macOS)
23: 
24: ```bash
25: # 1. Make the script executable
26: chmod +x /path/to/project/scripts/backup.sh
27: 
28: # 2. Prepare the launch agent: copy the template and fill in placeholders
29: cp /path/to/project/launchd/com.datasafe.backup.plist \
30:    "$HOME/Library/LaunchAgents/com.datasafe.backup.plist"
31: 
32: # Replace __SCRIPT_PATH__ and __LOG_DIR__ (adjust the project path):
33: sed -i '' \
34:   -e "s|__SCRIPT_PATH__|/path/to/project/scripts/backup.sh|g" \
35:   -e "s|__LOG_DIR__|$HOME/.backups/logs|g" \
36:   "$HOME/Library/LaunchAgents/com.datasafe.backup.plist"
37: 
38: mkdir -p "$HOME/.backups/logs"
39: ```
40: 
41: ## Load / Unload
42: 
43: ```bash
44: # Load (runs immediately once due to RunAtLoad, then hourly)
45: launchctl load  "$HOME/Library/LaunchAgents/com.datasafe.backup.plist"
46: 
47: # Check status
48: launchctl list | grep com.datasafe.backup
49: 
50: # Unload / disable
51: launchctl unload "$HOME/Library/LaunchAgents/com.datasafe.backup.plist"
52: ```
53: 
54: On modern macOS (10.10+) you may prefer the bootstrap equivalents:
55: 
56: ```bash
57: launchctl bootstrap   gui/$(id -u) "$HOME/Library/LaunchAgents/com.datasafe.backup.plist"
58: launchctl bootout     gui/$(id -u) "$HOME/Library/LaunchAgents/com.datasafe.backup.plist"
59: ```
60: 
61: ## Test
62: 
63: ```bash
64: # Dry validation of the script syntax
65: bash -n scripts/backup.sh
66: 
67: # Manual run (safe to run any time; skips missing sources)
68: bash scripts/backup.sh
69: 
70: # Inspect results
71: ls -la ~/.backups/snapshots/
72: tail -n 50 ~/.backups/logs/backup.log
73: 
74: # Validate the plist
75: plutil -lint "$HOME/Library/LaunchAgents/com.datasafe.backup.plist"
76: 
77: # Trigger the agent on demand
78: launchctl start com.datasafe.backup
79: ```
80: 
81: ## Optional: encrypted cloud sync (restic + S3)
82: 
83: ```bash
84: brew install restic
85: export RESTIC_PASSWORD='your-strong-passphrase'      # never commit this
86: export AWS_ACCESS_KEY_ID='...'
87: export AWS_SECRET_ACCESS_KEY='...'
88: bash scripts/backup.sh   # will init the repo on first run and push the snapshot
89: ```
90: 
91: To let the launchd job pick up credentials, export them in your shell profile
92: **before** loading the agent, or wrap the script with a keychain lookup. Do **not**
93: put secrets in the plist or in `config.yaml`.
94: 
95: ## Security notes
96: 
97: - No `eval`, no hardcoded credentials, no secrets written to logs or the plist.
98: - `~` expansion is done in pure bash string manipulation, not `eval`.
99: - Pruning only deletes directories matching the snapshot timestamp pattern inside
100:   the snapshots directory — it cannot touch arbitrary paths.
101: - A `flock` lock (when available) prevents overlapping hourly runs.
102: - The destination is excluded as a source to prevent recursive self-backup.
103: - Cloud sync is strictly opt-in via environment variables; without them the job is
104:   fully local.
105: - Logs live in `~/.backups/logs/`; launchd stdout/stderr go to the paths set in the plist.
106: 
107: ## Restoring
108: 
109: Snapshots are plain directory trees — copy files back directly:
110: 
111: ```bash
112: cp -R ~/.backups/snapshots/latest/Documents/important.txt ~/Documents/
113: ```
114: 
115: Or restore from restic:
116: 
117: ```bash
118: restic snapshots
119: restic restore latest --target /tmp/restore
120: ```
