[Feature] add no compression option for backups

My setup is pretty simple: backups are saved to an s3 bucket using restic. In my tests, if backups were not compressed, I would be uploading ~20MB per day due to deduplication that restic does. With compression, I'm uploading 500MB per day. I'm not an expert in compression, but I think the factor at play here is the chunking that restic does is in segments too large compared to the gzip rsyncable chunks (or maybe just a different algorithm) I'd like to proposed a fix, that I'll submit a PR for: Add an option to not compress backups, with a toggle in the admin panel.
