Automated backup skill for PKA + Obsidian + Claude memory. Snapshots pka.db (via SQLite .backup so WAL is handled safely), the Obsidian vault, Claude memory files, agent profiles, and the help-content Excel into a single timestamped zip in Zoho WorkDrive. Daily/weekly/monthly retention rotation built in. USE WHEN Danny says "backup", "run backup", "snapshot pka", or to recover from a snapshot.

PKA Backup
THIS SKILL HAS FUNCTIONAL CODE. See pka_backup.py.
When to Use
Use this skill when:
- Danny says "backup", "run backup", "snapshot pka", "back up everything"
- It's been more than 24 hours since the last snapshot (check
BACKUP_ROOTmtime) - Before any risky operation (schema migration, mass delete, viewer rewrite)
- After a major content edit (large Obsidian session, batch journal entries, big Excel update)
- After a hardware change or before traveling
Use the restore mode when:
- Danny says "restore from backup", "I lost X", "yesterday's pka.db"
What gets backed up
A single timestamped zip — written to TWO destinations for 3-2-1 backup-rule compliance:
- Primary:
C:\Users\dansk\Zoho WorkDrive (Go Biz IT)\00 Claude.ai\Backups\PKA\pka-backup-YYYY-MM-DD_HHMMSS.zip - Mirror:
C:\Users\dansk\Dropbox\PKA-Backups\pka-backup-YYYY-MM-DD_HHMMSS.zip(different cloud provider — true offsite redundancy)
Each zip contains:
| Inside the zip | Source |
|----------------|--------|
| pka.db | @team-ai.biz/data/pka.db (via SQLite .backup — WAL-safe) |
| obsidian/... | Entire Obsidian@Claude/ tree (excluding .git, .obsidian/workspace*, etc.) |
| memory/... | ~/.claude/projects/c--Users-dansk-Claude/memory/ (Claude auto-memory) |
| agents-global/... | ~/.claude/agents/*.md |
| agents-project/... | @team-ai.biz/.claude/agents/*.md |
| help-content.xlsx | @team-ai.biz/data/help-content.xlsx (Danny's help editorial source) |
| manifest.json | Source paths, byte counts, UTC timestamp |
Retention policy
- 7 daily snapshots (anything in the last 7 days)
- 4 weekly snapshots (one per week, latest of the week)
- 6 monthly snapshots (one per month, latest of the month)
Older snapshots are deleted on the next cleanup pass. Total typical footprint: ~17 snapshots.
HOW TO INVOKE
# Take a snapshot now (default: also runs retention cleanup)
python C:/Users/dansk/.claude/skills/pka-backup/pka_backup.py
# Dry-run — show what would happen, no writes
python C:/Users/dansk/.claude/skills/pka-backup/pka_backup.py --dry-run
# Only run retention cleanup, no new snapshot
python C:/Users/dansk/.claude/skills/pka-backup/pka_backup.py --cleanup
# Skip retention after snapshot
python C:/Users/dansk/.claude/skills/pka-backup/pka_backup.py --no-cleanup
# Restore a snapshot to <BACKUP_ROOT>/restore/ (does NOT overwrite source — manual review required)
python C:/Users/dansk/.claude/skills/pka-backup/pka_backup.py --restore "C:/Users/dansk/Zoho WorkDrive (Go Biz IT)/00 Claude.ai/Backups/PKA/pka-backup-2026-04-25_103045.zip"
Auto-schedule (optional)
Run install_schedule.ps1 once (as admin) to register a Windows Task Scheduler job that runs daily at 03:00. Uninstall via the same script with -Uninstall.
Restore protocol
The restore command extracts to <BACKUP_ROOT>/restore/. It does NOT automatically overwrite source paths. Reason: restore is rare and high-stakes; manual review prevents accidents. Workflow:
- Run
pka_backup.py --restore <zip>— extracts toBackups/PKA/restore/ - Open the extracted tree, verify the files you want
- Copy them manually to source locations (or close apps + use a backup-aware copy script)
Dependencies
- Python 3.x (uses stdlib only:
sqlite3,zipfile,shutil,pathlib,argparse,json,datetime,hashlib) - No
pip installneeded - Windows file system access to source paths + Zoho WorkDrive folder
Sample output

testing
VerifiedTrustedCommunity
Run any question, idea, or decision through a council of 5 AI advisors who independently analyze it, peer-review each other anonymously, and synthesize a final verdict. Based on Karpathy's LLM Council methodology, packaged as the stress-test skill. MANDATORY TRIGGERS: 'stress-test this', 'stress test this', 'pressure-test this', 'pressure test this', 'war room this', 'council this', 'run the council', 'debate this'. STRONG TRIGGERS (use when combined with a real decision or tradeoff): 'should I X or Y', 'which option', 'what would you do', 'is this the right move', 'validate this', 'get multiple perspectives', 'I can't decide', 'I'm torn between'. Do NOT trigger on simple yes/no questions, factual lookups, or casual 'should I' without a meaningful tradeoff (e.g. 'should I use markdown' is not a stress-test question). DO trigger when the user presents a genuine decision with stakes, multiple options, and context that suggests they want it pressure-tested from multiple angles.
