ZipFile.write() raises ValueError for files with mtime before 1980-01-01
(the ZIP format uses MS-DOS timestamps which can't represent earlier dates).
This crashes the entire backup. Add ValueError to the existing except clause
so these files are skipped and reported in the warnings summary, matching the
existing behavior for PermissionError and OSError.
Three changes consolidated into the existing backup system:
1. Fix: hermes backup now uses sqlite3.Connection.backup() for .db files
instead of raw file copy. Raw copy of a WAL-mode database can produce
a corrupted backup — the backup() API handles this correctly.
2. hermes backup --quick: fast snapshot of just critical state files
(config.yaml, state.db, .env, auth.json, cron/jobs.json, etc.)
stored in ~/.hermes/state-snapshots/. Auto-prunes to 20 snapshots.
3. /snapshot slash command (alias /snap): in-session interface for
quick state snapshots. create/list/restore/prune subcommands.
Restore by ID or number. Powered by the same backup module.
No new modules — everything lives in hermes_cli/backup.py alongside
the existing full backup/import code.
No hooks in run_agent.py — purely on-demand, zero runtime overhead.
Closes the use case from PRs #8406 and #7813 with ~200 lines of new
logic instead of a 1090-line content-addressed storage engine.
The backup validation checked for 'hermes_state.db' and 'memory_store.db'
as telltale markers of a valid Hermes backup zip. Neither name exists in a
real Hermes installation — the actual database file is 'state.db'
(hermes_state.py: DEFAULT_DB_PATH = get_hermes_home() / 'state.db').
A fresh Hermes installation produces:
~/.hermes/state.db (actual name)
~/.hermes/config.yaml
~/.hermes/.env
Because the marker set never matched 'state.db', a backup zip containing
only 'state.db' plus 'config.yaml' would fail validation with:
'zip does not appear to be a Hermes backup'
and the import would exit with sys.exit(1), silently rejecting a valid backup.
Fix: replace the wrong marker names with the correct filename.
Adds TestValidateBackupZip with three cases:
- state.db is accepted as a valid marker
- old wrong names (hermes_state.db, memory_store.db) alone are rejected
- config.yaml continues to pass (existing behaviour preserved)
* feat: add `hermes backup` and `hermes import` commands
hermes backup — creates a zip of ~/.hermes/ (config, skills, sessions,
profiles, memories, skins, cron jobs, etc.) excluding the hermes-agent
codebase, __pycache__, and runtime PID files. Defaults to
~/hermes-backup-<timestamp>.zip, customizable with -o.
hermes import <zipfile> — restores from a backup zip, validating it
looks like a hermes backup before extracting. Handles .hermes/ prefix
stripping, path traversal protection, and confirmation prompts (skip
with --force).
29 tests covering exclusion rules, backup creation, import validation,
prefix detection, path traversal blocking, confirmation flow, and a
full round-trip test.
* test: improve backup/import coverage to 97%
Add 17 additional tests covering:
- _format_size helper (bytes through terabytes)
- Nonexistent hermes home error exit
- Output path is a directory (auto-names inside it)
- Output without .zip suffix (auto-appends)
- Empty hermes home (all files excluded)
- Permission errors during backup and import
- Output zip inside hermes root (skips itself)
- Not-a-zip file rejection
- EOFError and KeyboardInterrupt during confirmation
- 500+ file progress display
- Directory-only zip prefix detection
Remove dead code branch in _detect_prefix (unreachable guard).
* feat: auto-restore profile wrapper scripts on import
After extracting backup files, hermes import now scans profiles/ for
subdirectories with config.yaml or .env and recreates the ~/.local/bin
wrapper scripts so profile aliases (e.g. 'coder chat') work immediately.
Also prints guidance for re-installing gateway services per profile.
Handles edge cases:
- Skips profile dirs without config (not real profiles)
- Skips aliases that collide with existing commands
- Gracefully degrades if hermes_cli.profiles isn't available (fresh install)
- Shows PATH hint if ~/.local/bin isn't in PATH
3 new profile restoration tests (49 total).
