Obnam is described as 'Easy, secure backup program. Backups can be stored on local hard disks, or online via the SSH SFTP protocol. The backup server, if used, does not require any special software, on top of SSH' and is an app in the backup & sync category. There are more than 10 alternatives to Obnam for a variety of platforms, including Linux, Mac, Windows, BSD and Cygwin apps. The best Obnam alternative is Duplicati, which is both free and Open Source. Other great apps like Obnam are rsync, BorgBackup, Déjà Dup and Areca Backup.
Duplicati stores encrypted, incremental backups with AES-256 encryption and GPG, compatible with Windows, Linux, MacOS. Supports cloud services like OneDrive, Google Drive, and includes a built-in scheduler, auto-updater. Run backups through a web interface or command line.
rsync is a software application for Unix which synchronizes files and directories from one location to another while minimizing data transfer using delta encoding when appropriate. An important feature of rsync not found in most similar programs/protocols is that the mirroring...
BorgBackup (short: Borg) is a deduplicating backup program. Optionally, it supports compression and authenticated encryption.
Déjà Dup is a simple backup tool. It hides the complexity of doing backups the Right Way (encrypted, off-site, and regularly) and uses Restic behind the scenes.
Areca Backup is a file backup software which can be run on Windows or Linux. It creates backup copies (which can be encrypted and compressed) of your files and stores them on external drives, USB keys, FTP servers, supporting incremental, differential and full backups.
rdiff-backup backs up one directory to another, possibly over a network. The target directory ends up a copy of the source directory, but extra reverse diffs are stored in a special subdirectory of that target directory, so you can still recover files lost some time ago.
Duplicity is a software suite that provides encrypted, digitally signed, versioned, remote backup of files requiring little of the remote server.
Burp is a network backup and restore program. It uses librsync in order to save network traffic and to save on the amount of space that is used by each backup. It also uses VSS (Volume Shadow Copy Service) to make snapshots when backing up Windows computers.
A graphical user interface for rsync, which looks-and-feels like a standard FTP client, but uses the rsync protocol ‘under the hood’ to boost transfer speeds.
