+  * use `--hist` or the `hist` volflag (`-v [...]:c,hist=/tmp/foo`) to place the db on a local disk instead

+## ftp-server
+
+an FTP server can be started using `--ftp 2121` (or any other port)
+
+* based on [pyftpdlib](https://github.com/giampaolo/pyftpdlib)
+* needs a dedicated port (cannot share with the HTTP/HTTPS API)
+* runs in active mode by default, you probably want `--ftp-r`

 ## file indexing
 
 file indexing relies on two database tables, the up2k filetree (`-e2d`) and the metadata tags (`-e2t`), stored in `.hist/up2k.db`. Configuration can be done through arguments, volume flags, or a mix of both.
