televault 2.6.2

Unlimited cloud storage using Telegram MTProto. No local DB - everything on Telegram.

TeleVault

Unlimited cloud storage using your own Telegram account. No local database — everything lives in a private Telegram channel, encrypted on your machine before upload.

What's New

Pipeable I/O

TeleVault commands are designed to work with Unix pipes:

# Upload from stdin
echo "hello world" | tvt push - --name note.txt
cat config.json | tvt push - --name config.json
mysqldump mydb | tvt push - --name db-backup.sql

# Download to stdout
tvt cat config.json | jq '.database'
tvt pull video.mp4 -o - | mpv -

# JSON output for scripting
tvt ls --json | jq '.[].name'
tvt stat --json | jq '.file_count'
tvt find "backup" --json | jq '.[].size'
tvt info photo.jpg --json | jq '.hash'

---

Upload Options

# Upload with encryption (default)
televault push myfile.txt --password mypassword

# Upload without encryption
televault push myfile.txt --no-encrypt

# Upload directory recursively
televault push myfolder/ -r

# Resume interrupted upload
televault push largefile.zip --resume

Download Options

# Download with decryption
televault pull myfile.txt --password mypassword

# Download to specific path
televault pull myfile.txt --output /path/to/save

# Resume interrupted download
televault pull largefile.zip --resume

---

Backup & Restore

TeleVault supports git-like backup snapshots of directories:

# Create a full backup
televault backup create /important/data --name "daily-backup"

# Create an incremental backup (only changed files)
televault backup create /important/data --name "daily" --incremental

# Dry run (show what would be backed up)
televault backup create /important/data --dry-run

# List all snapshots
televault backup list

# Restore from a snapshot
televault backup restore <snapshot_id> --output /restore/path

# Restore specific files
televault backup restore <snapshot_id> --output /restore/path --files docs/readme.md

# Verify snapshot integrity
televault backup verify <snapshot_id>

# Prune old snapshots (keep last 7 daily, 4 weekly, 6 monthly)
televault backup prune --keep-daily 7 --keep-weekly 4 --keep-monthly 6

# Dry-run prune
televault backup prune --dry-run

# Delete a specific snapshot
televault backup delete <snapshot_id>

How It Works

• Each snapshot stores file metadata (path, hash, size, file ID)
• Only changed files are uploaded in incremental backups
• Snapshots reference files already in the vault (deduplication)
• Restore downloads files from the vault using their file IDs
• Pruning respects retention policies (daily/weekly/monthly)

Virtual Drive

FUSE Mount (Linux/macOS)

Mount your TeleVault as a local directory:

# Install FUSE support
pip install televault[fuse]

# Create mount point
mkdir -p ~/televault-drive

# Mount the vault
televault mount -m ~/televault-drive

# Read-only mount
televault mount -m ~/televault-drive --read-only

# Unmount (Ctrl+C or)
fusermount -u ~/televault-drive

Requirements:

• Linux: sudo apt install fuse libfuse2
• macOS: Install macFUSE

WebDAV Server (All Platforms)

Access your vault over HTTP/WebDAV from any device:

# Install WebDAV support
pip install televault[webdav]

# Start server on default port 8080
televault serve

# Custom host and port
televault serve --host 0.0.0.0 --port 9090

# Read-only server
televault serve --read-only

Connect from any WebDAV client:

• macOS Finder: Go → Connect to Server → http://localhost:8080/
• Windows: Map Network Drive → http://localhost:8080/
• Linux: davfs2 or file manager WebDAV support
• Mobile: Documents by Readdle, Solid Explorer, etc.

Auto Backup

Scheduled Backups

Create schedules that run automatically via systemd timers or cron:

# Create a daily backup schedule
televault schedule create /important/data --name "daily-docs" --interval daily

# Create an hourly incremental schedule
televault schedule create /important/data --name "hourly-sync" --interval hourly --incremental

# List all schedules
televault schedule list

# Run a schedule manually
televault schedule run daily-docs

# Install as systemd timer (Linux)
televault schedule install daily-docs

# Show systemd unit files without installing
televault schedule show-systemd daily-docs

# Uninstall systemd timer
televault schedule uninstall daily-docs

# Delete a schedule
televault schedule delete daily-docs

File Watcher

Watch directories for changes and automatically upload new/modified files:

# Watch a directory
televault watch --path /important/docs

# Watch multiple directories
televault watch --path /docs --path /photos --path /projects

# Custom poll interval (default: 5 seconds)
televault watch --path /docs --interval 10

# Exclude custom patterns
televault watch --path /docs --exclude "*.tmp" --exclude "build/"

The watcher detects new files and file modifications, automatically uploading changes to your vault.

Data Safety

TeleVault is designed for people who care about their data:

• Retry Logic — All Telegram operations retry 3x with exponential backoff
• Atomic Index Updates — Version-based concurrency control prevents data races
• Upload Cleanup — Failed uploads automatically delete orphaned messages
• Hash Verification — Every chunk is verified with BLAKE3 on download
• Original Hash — Separate hash for pre-encryption data catches wrong-password errors
• Progress Integrity — CRC32 checksums on resume files detect corruption
• Parallel Downloads — Configurable concurrency for faster downloads
• Garbage Collection — Find and remove orphaned messages

---

Interactive TUI

Launch the Terminal User Interface for visual file management:

televault tui

TUI Features

• File Browser — Browse all files with icons, sizes, and encryption status
• Progress Bars — Real-time upload/download progress with chunk counts
• Search — Live search through your files
• Confirmations — Safe delete with confirmation dialogs
• Login Flow — Complete login flow with 2FA support

Keyboard Shortcuts

Key	Action
q	Quit
u	Upload file
d	Download file
/	Search
Delete	Delete file (with confirmation)
l	Login
r	Refresh

---

Resumable Transfers

Large file transfers can be interrupted. Resume them with:

# Resume upload
televault push largefile.zip --resume

# Resume download
televault pull largefile.zip --resume

Progress is tracked per-chunk with CRC32 integrity checks.

---

Security Model

TeleVault encrypts data before it leaves your machine:

• AES-256-GCM encryption with password-derived keys
• scrypt key derivation (memory-hard)
• BLAKE3 hashing for chunk verification
• zstd compression (optional)

Your password never leaves your machine. Telegram only sees encrypted blobs and JSON metadata.

Important: If you lose your password and have encryption enabled, there is no recovery.

---
