Compression, Deduplication and Pruning

[apiening]

I like the web interface and the simplicity. Especially the fact that there are no client requirements other than having an SSH server running is really nice. The pre and post-commands are awesome.

I gave it a quick try out of curiosity but discovered a few shortcomings for my use-cases:

• It seems all files are transferred fully on each backup run, there is no differential file transfer option like with rsync for example
• There is no de-duplication happening, not on file and not on the block level (like rclone, dirvish or borgbackup) and no compression either
• There is no auto prune option to remove old backups (like keep the latest 14 backups and delete older ones automatically)

Are you thinking about these features?
At this stage, I see this tool as an option to backup small DB instances and remote folders but not as a long term backup option for VPS or something similar. Which is completely fine of course. I would like to understand the direction / goal of the project.

Hi, thank you for your feedback.

Those are some aspects that came to my mind as well.

The goal of this project was (and is) to keep it very lightweight. Personally, I just wanted to get rid of my shell scripts and systemd services.

Concerning deduplication and compression, you could use the post and pre commands for this, though it will be very messy so it would be nice to have it built in.
The auto pruning would be very nice to have as well and I might implement that, though it is always a security risk to allow an app to delete files so the effort for implementing that feature and making sure nothing can go wrong is very high.

When posting about this project on reddit, I did not expect it to get this much attention, so my initial goal was "make it work, use it and never touch it again" :)
I might have to rethink that.
