I would strongly recommend against using Seafile.

Seafile stores a lot of metadata in clear text (including filenames): https://github.com/haiwen/seafile/issues/350

The developers know about it, the issue is 3 years old, this huge limitation is still not reflected on their documentation.

  An attacker who obtains a copy of the encrypted library without the key can:
 
  - read the complete list of directory and file names.
  - know the size of every file
  - know which files share some of the same information
  - see the history of who changed each file, when, and what byte ranges were altered
