Can't answer your direct question as my use-case doesn't include send/ receive, but... ~900TiB receive on a 24TB (6x4TB) raid0? Did you mean ~900GiB, or did you miss the decimal point, or ???? I mean, yeah, btrfs does have the compress= option, but I don't think it's going to compress 900 TiB to fit in under 24! That's likely to be some seriously lossy compression! -- Duncan - List replies preferred. No HTML msgs. "Every nonfree program has a lord, a master -- and if you use the program, he is your master."
