Configuration

Configuration Reference

Complete reference for config.toml — the Cloud Drive Sync configuration file.

Not configured here: the HTTP server (web UI + REST API) and the MCP server for AI assistants are enabled by command-line flags or environment variables, not by config.toml — they are per-invocation deployment choices rather than persistent settings. See HTTP Server, MCP Server and the CLI options.

File Location

The configuration file is created automatically on first run with sensible defaults. You do not need to create it manually.

Platform	Default path
Linux	~/.config/cloud-drive-sync/config.toml
macOS	~/Library/Application Support/cloud-drive-sync/config.toml
Windows	%APPDATA%\cloud-drive-sync\config.toml

To use a different path, pass --config PATH to any command:

cloud-drive-sync --config /etc/cloud-drive-sync/config.toml start --foreground

Section Reference

[general]

Key	Type	Default	Description
log_level	string	"info"	Logging verbosity: "debug", "info", "warning", "error"

---

[sync]

Global sync behavior. All settings here can be overridden per pair where noted.

Key	Type	Default	Description
poll_interval	integer	30	Seconds between remote change polls
stopped	boolean	false	Emergency stop state; set by the UI/CLI, not meant for hand-editing — see Emergency Stop
max_deletions_per_sync	integer	100	Refuse deletions exceeding this many files in one direction within deletion_window_seconds, until confirmed. 0 disables the guard — see Delete Protection
deletion_window_seconds	integer	60	Sliding window the deletion cap is counted over, across sync passes. 0 = per pass only
conflict_strategy	string	"keep_both"	Default conflict resolution strategy (see values below)
max_concurrent_transfers	integer	4	Parallel upload/download limit
debounce_delay	float	1.0	Seconds to wait after a local change before syncing
convert_google_docs	boolean	true	Export Google Docs/Sheets/Slides to Office formats on download
notify_sync_complete	boolean	true	Desktop notification when a sync cycle completes
notify_conflicts	boolean	true	Desktop notification when a conflict is detected
notify_errors	boolean	true	Desktop notification on sync errors
max_upload_kbps	integer	0	Upload bandwidth cap in KB/s; 0 = unlimited
max_download_kbps	integer	0	Download bandwidth cap in KB/s; 0 = unlimited

Conflict strategy values

Value	Behavior
"keep_both"	Rename the conflicting version (e.g. file (conflict 2024-01-15).txt) and keep both. Default.
"newest_wins"	Keep whichever version has the most recent modification time; discard the other.
"ask_user"	Pause the conflict for manual resolution. Visible in the UI under Conflicts and via cloud-drive-sync conflicts.
"local_wins"	Always keep the local copy; discard the remote change.
"remote_wins"	Always keep the remote copy; discard the local change.

---

[[sync.pairs]]

One [[sync.pairs]] section per sync pair. Multiple pairs are supported.

Key	Type	Default	Description
local_path	string	(required)	Absolute path to the local directory
remote_folder_id	string	"root"	Remote folder — Drive folder ID, "root" for Drive root, or path for Nextcloud/Dropbox/OneDrive
account_id	string	(required)	Email of the account to use
provider	string	(required)	"gdrive", "nextcloud", "dropbox", "onedrive", or "box"
enabled	boolean	true	Whether this pair is active
sync_mode	string	"two_way"	"two_way", "upload_only", or "download_only"
ignore_hidden	boolean	true	Exclude files and directories whose names start with .
ignore_patterns	list of strings	[]	Glob patterns for files to exclude (see Selective Sync below)
conflict_strategy	string	(inherits global)	Per-pair conflict strategy; overrides [sync].conflict_strategy if set
max_deletions_per_sync	integer	(inherits global)	Per-pair delete cap; 0 disables delete protection for this pair
deletion_window_seconds	integer	(inherits global)	Per-pair window for the delete cap
force_polling	boolean	false	Nextcloud only: skip notify_push and always walk the tree — see Nextcloud Change Detection

sync_mode values

Value	Description
"two_way"	Changes on either side are synced to the other.
"upload_only"	Local changes are uploaded; remote changes are ignored.
"download_only"	Remote changes are downloaded; local changes are ignored.

---

[[accounts]]

One [[accounts]] section per cloud account. Accounts are normally managed via cloud-drive-sync account add and written to this section automatically — you rarely need to edit this by hand.

Key	Type	Description
email	string	Account identifier (email address)
display_name	string	Human-readable label shown in the UI
provider	string	"gdrive", "nextcloud", "dropbox", "onedrive", or "box"
server_url	string	Nextcloud only — base URL of the Nextcloud server, e.g. https://cloud.example.com

Credentials (OAuth tokens, app passwords) are stored separately in the system keychain, not in config.toml.

Selective Sync (Ignore Patterns)

There are two ways to exclude files from syncing.

Method 1: ignore_patterns in config

Add glob patterns to the ignore_patterns list of a sync pair:

[[sync.pairs]]
local_path = "/home/alice/Documents"
# ...
ignore_patterns = [
    "*.tmp",
    "*.log",
    "~$*",
    "node_modules/",
    "build/",
    ".venv/",
]

Patterns are matched against file names (not full paths). A trailing / matches directories only.

Method 2: .cloud-drive-sync-ignore file

Place a .cloud-drive-sync-ignore file in the root of any synced folder. It uses the same syntax as .gitignore:

# Ignore all log files
*.log

# Ignore temp files
*.tmp
~$*

# Ignore build output directories
build/
dist/
.cache/

# Ignore Python virtual environments
.venv/
__pycache__/
*.pyc

# Ignore a specific file
secrets.txt

# Ignore everything in a subdirectory except one file
private/*
!private/README.md

The .cloud-drive-sync-ignore file itself is never synced.

---

Per-folder Ignore File

The .cloud-drive-sync-ignore file in a sync folder's root applies only to that folder. Subdirectories do not have their own ignore files — patterns from the root file apply recursively to the entire sync tree.

Built-in defaults (always excluded)

The following are excluded from every sync pair regardless of configuration:

Pattern	Reason
.git/	Git repository metadata — syncing this causes repository corruption
__pycache__/	Python bytecode cache — platform-specific, regenerated automatically
.DS_Store	macOS Finder metadata
Thumbs.db	Windows Explorer thumbnail cache
.Trash-*/	Linux trash directories

These cannot be overridden — they are hardcoded as safety defaults to prevent common mistakes.
