What Webdar is

Webdar is a free, open-source backup tool delivered as a small single executable combining a web server with the libdar library. It runs on Linux or as a self-hosted service on the machine holding the data, and you operate it through a browser. Backups can be full, differential, incremental, or decremental. Features include binary deltas, filtering, sliced archives, sparse files, extended attributes, inode types, hard links, and selected-file restoration. Compression options include gzip, bzip2, lzo, xz/lzma, zstd, and lz4. Webdar describes encryption with key derivation and per-slice hashing, with strong ciphering by default. Local storage and FTP or SFTP transfer and restoration are supported. Operations include creation, testing, comparison, listing, isolation, merging, repair, and restoration. Signed source packages and statically linked, distro-independent Linux binaries are available for x86_64 and ARM. The current setup provides an admin user; additional users are planned.

Who it suits

Webdar suits Linux users and self-hosting administrators who need browser-based file backup and restoration. It is also relevant when local, FTP, or SFTP repositories are needed.

What it does well

Supports four backup types
Offers multiple compression algorithms
Includes FTP and SFTP clients
Provides encrypted backups by default
Linux binaries support x86_64 and ARM

What to know first

Mobile backup is not supported
Only an admin user is currently available
HTTPS is recommended on untrusted networks

Verdict

Webdar provides a broad libdar-backed backup interface in a compact, self-hosted package. Its main constraints are the Linux-focused availability, absent mobile backup and ransomware protection, and current single-admin user model.
