Does anyone already use zstd https://en.wikipedia.org/wiki/Zstandard with amanda?
I will try to define an initial dumptype and play around although I wonder if the standard behavior leads to any problems. zstd does not remove the source file after de/compression per default (only with "--rm") ... but as it is used within a pipe (?) with amanda I assume that won't hurt. The "-d" for decompression is there so that should work.
