I’m running my own hand-crafted remote backup (rsync++) script to back up data from one machine to another. But, it has some serious drawbacks, and I’m still looking for something better. Here are my requirements:
- Runs on Ubuntu
- Is either:
- Available in the standard distro (i.e. via apt-get)
- A simple self-contained script (Python, Perl, Bash, etc.)
- Uses ssh/scp/rsync to transport files
- Is incremental (i.e. does “what’s changed from last time”, and only backs up that much)
- Handles file renames & moves without re-transmitting the underlying data.
- Puts files in a simple “directory by date” format. No fancy databases, no fancy metadata required for restoring.
- Preserves file permissions & modification dates.
- Correctly handles both hard & soft symbolic links.
- Is client-side only. In other words, I don’t want to have to maintain 2 copies of this script, one for the server, and one for the client.
Is there anything out there that meets these requirements?
