Reduce local disk space needs by not (redundantly) gzipping backups

The backup process creates a tar file and then applies gzip to it. There are two types of things in the tar file: an already gzipped sql dump and the contents of uploads (if requested.) In my case every upload file is already compressed: gz, gzip, gif, jpeg, png, zip. So the final gzipping gains only 1% of size.

I believe it would be better to demand less free space.

A previous topic from 2016 mentions disabling backup compression, but it looks like the sql dump was at that time not compressed, which shifted the tradeoffs.

Add option to disable backup compression


I’m already working on a new backup format that removes the double compression. My hope is that it will be ready within a month or two.


Sounds great @gerhard!
