Why Seafile over Nextcloud or Syncthing?
Three popular tools, three distinct use cases:
- Nextcloud is a full office suite (calendar, contacts, mail, app store). Feature-rich, but heavier — plan 2 to 4 GB of RAM for comfortable use.
- Syncthing is peer-to-peer: your devices sync directly with each other, no central server. Great for two machines, but no user accounts or shared web interface.
- Seafile is client-server and focuses solely on file synchronisation. Its engine transfers only the changed blocks, not entire files — making it extremely efficient on large folders or slow connections.
For a team that wants a private Dropbox without the complexity of an office suite, Seafile is the right choice.
What you get with a Seafile installation on SerVorbit
The Seafile installation automatically deploys: seafile-mc (Seafile + Seahub + Memcached in a single container) for the web interface, REST API and file server; MariaDB 10.11 for metadata (libraries, users, permissions, history); and an nginx reverse proxy on the host that handles TLS with an automatic Let's Encrypt certificate.
Your files and database are stored on named Docker volumes (seafile_data, seafile_mysql) — they survive container updates. The initial admin account is [email protected] with the generated password visible in your Client Area.
Client-side encryption: your files stay private, even from the host
Seafile offers end-to-end encryption at the library level. When you create an encrypted library, you define a passphrase on the client side. The client encrypts each block before sending it to the server, which stores only ciphertext — it mathematically cannot decrypt your files without the passphrase.
In practice: even if someone gains access to your VPS, your backups, or the MariaDB database, your files remain unreadable. Store your passphrase in a password manager: if you lose it, the files are permanently unrecoverable.
Block-level sync: fast even on a slow connection
Most sync services transfer the entire file on every change. Seafile splits each file into fixed-size blocks and only sends the blocks that changed.
Example: you update 3 slides in a 500 MB PowerPoint file. Seafile transfers a few MB — not 500 MB. On a 1 Mbps upload ADSL connection, the difference is a few seconds vs over an hour. This makes Seafile particularly suited for teams working on heavy assets (video files, exported designs, photo archives).
Getting started: creating libraries and inviting your team
Change the admin email and password
Log in with [email protected] and the generated password. In Admin Panel → Users, edit the admin account: set your real email address and a strong password.
Create your first library
Click My Libraries → New Library. Give it a name (e.g. 'Client Assets'), choose whether to encrypt it (you will be prompted for a passphrase), then click Create.
Invite team members
In Admin Panel → Users, click Add User, enter the email, name and role. The user receives an invitation email to set their password.
Install the desktop client and sync
Download the Seafile client (Windows/Mac/Linux) from seafile.com. Connect it to your server URL and authenticate — your libraries appear and sync automatically.
