You can edit this file manually or use the `rclone config` command.
Basic Operations
Once configured, you can perform various operations with your cloud storage.
Listing Remotes
View all configured remotes:
```bash
rclone listremotes
```
Listing Files and Directories
List contents of a remote:
```bash
List root directory
rclone ls gdrive:
List specific directory
rclone ls gdrive:Documents/
List with details (size, modification time)
rclone lsl gdrive:Documents/
List directories only
rclone lsd gdrive:
```
Copying Files
Copy from Local to Cloud
```bash
Copy single file
rclone copy /home/user/document.pdf gdrive:Documents/
Copy entire directory
rclone copy /home/user/photos/ gdrive:Photos/
Copy with progress display
rclone copy /home/user/backup/ gdrive:Backup/ --progress
```
Copy from Cloud to Local
```bash
Copy single file
rclone copy gdrive:Documents/report.pdf /home/user/downloads/
Copy entire directory
rclone copy gdrive:Photos/ /home/user/pictures/
```
Copy Between Cloud Services
```bash
Copy from Google Drive to Amazon S3
rclone copy gdrive:Documents/ s3-storage:my-bucket/documents/
```
Synchronizing Directories
Synchronization ensures the destination matches the source exactly:
```bash
Sync local to cloud (one-way)
rclone sync /home/user/documents/ gdrive:Documents/
Sync cloud to local (one-way)
rclone sync gdrive:Documents/ /home/user/documents/
Bidirectional sync (use with caution)
rclone bisync /home/user/documents/ gdrive:Documents/
```
Moving Files
Move files instead of copying:
```bash
Move local file to cloud
rclone move /home/user/temp.txt gdrive:Temp/
Move cloud file to different location
rclone move gdrive:OldFolder/file.txt gdrive:NewFolder/
```
Deleting Files
```bash
Delete specific file
rclone delete gdrive:unwanted-file.txt
Delete empty directories
rclone rmdir gdrive:empty-folder/
Delete directory and all contents (use with extreme caution)
rclone purge gdrive:old-backup/
```

rclone copy /home/user/documents/ gdrive:Documents/ --include "*.pdf"
Exclude temporary files
rclone copy /home/user/project/ gdrive:Project/ --exclude "*.tmp"
Use filter file
rclone copy /home/user/data/ gdrive:Data/ --filter-from filter-rules.txt
```
Example filter file (`filter-rules.txt`):
```
+ *.jpg
+ *.png
+ *.pdf
- *.tmp
- .DS_Store
- Thumbs.db
```
Bandwidth Limiting
Control bandwidth usage:
```bash
Limit to 1MB/s
rclone copy /home/user/large-files/ gdrive:Backup/ --bwlimit 1M
Different limits for upload and download
rclone sync gdrive:Documents/ /home/user/docs/ --bwlimit 2M:1M
```

rclone md5sum gdrive:Documents/ > checksums.md5
Verify against checksums
rclone md5sum /home/user/documents/ | diff - checksums.md5
```
Automation and Scheduling
Creating Shell Scripts
Create reusable scripts for common operations:
```bash
#!/bin/bash
backup-script.sh
Set variables
SOURCE="/home/user/important-data"
DESTINATION="gdrive:Backups/$(date +%Y-%m-%d)"
LOG_FILE="/var/log/rclone-backup.log"
Perform backup
echo "Starting backup at $(date)" >> "$LOG_FILE"
rclone copy "$SOURCE" "$DESTINATION" \
--progress \
--log-file "$LOG_FILE" \
--log-level INFO
if [ $? -eq 0 ]; then
echo "Backup completed successfully at $(date)" >> "$LOG_FILE"
else
echo "Backup failed at $(date)" >> "$LOG_FILE"
exit 1
fi
```
Make the script executable:
```bash
chmod +x backup-script.sh
```
Scheduling with Cron
Set up automated backups using cron:
```bash
Edit crontab
crontab -e
Add entries for scheduled backups
Daily backup at 2 AM
0 2 * /home/user/scripts/backup-script.sh

```bash
# Create encrypted remote
rclone config create encrypted-remote crypt remote gdrive:encrypted password your-password
```
2. Secure Configuration: Protect your configuration file:
```bash
chmod 600 ~/.config/rclone/rclone.conf
```
3. Use Service Accounts: For automated operations, use service accounts instead of personal credentials.
4. Regular Key Rotation: Periodically rotate API keys and passwords.
Performance Best Practices
1. Optimize Transfer Settings:
```bash
# For fast connections
rclone copy source dest --transfers 8 --checkers 16 --buffer-size 64M
# For slow or unreliable connections
rclone copy source dest --transfers 1 --checkers 4 --buffer-size 16M
```
2. Use Appropriate VFS Settings:
```bash
# For read-heavy workloads
rclone mount remote: /mnt/point --vfs-cache-mode full --vfs-read-ahead 128M
# For write-heavy workloads
rclone mount remote: /mnt/point --vfs-cache-mode writes --buffer-size 32M
```
3. Monitor Resource Usage:
```bash
# Use system monitoring tools
htop
iotop
nethogs
```
Backup and Recovery Strategies
1. Implement 3-2-1 Backup Rule: Three copies of data, two different media types, one offsite.
2. Regular Testing: Periodically test restore procedures:
```bash
# Test restore to temporary location
rclone copy gdrive:Backup/test-file.txt /tmp/restore-test/
```
3. Version Control: Use cloud storage versioning features when available.
4. Documentation: Maintain detailed documentation of your rclone configurations and procedures.
