| Jun 10, 2023 at 7:49 | comment | added | Marcus Müller | By the way, the ability to have multiple concurrent streams is technically not a feature of ssh but of TCP/IP, ssh on top of that capability just also can internally and optionally transport multiple streams within one ssh connection. | |
| Jun 10, 2023 at 7:46 | comment | added | Marcus Müller | There's really nothing special to do, just for example use ssh to send that ZFS stream whilst using another ssh to copy that file; e.g. zfs send | zstd -10 | ssh user@host sh -c 'zstd -d | zfs receive tank/vm@snapshot' & cat somefile.txt | ssh user@host sh -c 'cat > somefile.txt'. | |

| Jun 9, 2023 at 23:12 | comment | added | David Scherfgen | Well, it's an example. Yes, I could transfer the files individually using multiple SSH connections, but it seemed "inelegant". | |
| Jun 9, 2023 at 23:06 | comment | added | Marcus Müller | Why would you put a zfs send stream into a tar archive? That makes no sense, tar archives are for files! I think you probably have a good intention there, but I don't quite get it. Couldn't you just have two ssh connections? | |
