DSM dropbox 與 google drive 同步資料夾共用的方法

1. Stop cloud sync service from package center

2. Create mount point in cloud sync directory (/volume1/google-drive in my case)

mkdir /volume1/google-drive/photo

3. Login to nas as root and mount actual local directory with data

mount --bind /volume1/photo /volume1/google-drive/photo

4. Start again cloud sync service

5. Don't forgot add this mounting to /etc/fstab for save this behavior after reboot

/volume1/photo /volume1/google-drive/photo none bind 0 0
