Web interface
Upload, download, and organise files in a browser. Files are grouped into libraries, which work like separate top-level folders. You can turn on two-factor authentication for your account.
What each service does.
File storage is for people who need to keep, sync, and share files. S3-compatible object storage is for applications and backup tools.
File storage
Keep, sync, and share files.
This service runs on Seafile, an open-source file sync and share platform. You sign in at cloud.digitalstorage.net, and your files are organised in libraries.
Desktop & mobile clients
Syncing and mobile access use the standard Seafile clients; we do not publish apps of our own. Install the Seafile desktop client or mobile app, enter our server address and your login, and choose which libraries to sync.
Share links
A file or a folder can be shared with a link. You can set a password and an expiry date on the link.
Version history & trash
The service keeps earlier versions of files and moves deleted files to the trash, so you can go back after an unwanted change or deletion.
Encrypted libraries
A library can be created as encrypted, with a password you choose. The desktop client encrypts files before uploading them, and the server does not keep the password. If you open such a library in the web interface, the password is sent to the server for that session. Encryption is not on by default: you choose it per library.
WebDAV
Libraries are also available over WebDAV, for file managers and tools that support it. rclone, for example, can connect over WebDAV or through its own Seafile backend.
S3 object storage
An S3 endpoint for applications and backups.
This is a separate service with its own endpoint. Here you work with buckets and access keys, not with libraries or the web file interface.
S3 API
We implement the parts of the S3 API that production workloads use: buckets, objects, multipart upload, listing with prefixes and delimiters, and presigned URLs. Existing SDKs and tools connect without custom code.
Encryption & access control
Every object is encrypted server-side. Access keys are scoped per bucket with read, write, and list permissions, so a key leaked from one application cannot be used to reach another team’s data.
Versioning & immutability
Versioning keeps earlier copies of each object. Object lock adds write-once-read-many retention: a locked version cannot be overwritten or deleted, whether by ransomware or by mistake.
Integrations
Any tool that speaks S3 can use the endpoint: restic and rclone for scripted backups, Duplicati and Veeam for scheduled jobs.
Operations
Data is stored redundantly on our own hardware. Our availability target is 99.9% a month. All data sits in one hot tier, so downloads start immediately and nothing has to be restored from cold storage.
