[Duplicity-talk] zstd compression

[Guy Rutenberg]

Hi,

Is there a way to compress backups using [zstd]? I know that normally in duplicity the compression is left to gpg, but gpg's selection for compression is quite limited and support basically gzip and bzip2. Zstd outperforms both algorithms in terms of compression and speed.

Ideally, I would like to give duplicity a command through which it pipes the tar archives before passing it on to gpg.

Thanks,
