推荐答案

gcloud compute copy-files 由SCP支持，不支持增加文件上传。

gcloud compute copy-files is backed by SCP, which has no support for incremental file uploads.

可以使用任何使用SSH协议的工具（如 rsync ）获取增量上传。 gcloud compute copy-files --dry-run 将显示您使用的SSH选项：

That said, you can use any tool that uses the SSH protocol (like rsync) to get incremental uploads. gcloud compute copy-files --dry-run will show you the SSH options used:

$ gcloud compute copy-files --dry-run --zone asia-east1-c /tmp/test.data zjn-nix:
/usr/local/bin/scp -i /Users/zjn/.ssh/google_compute_engine -o UserKnownHostsFile=/Users/zjn/.ssh/google_compute_known_hosts -o IdentitiesOnly=yes -o CheckHostIP=no -o HostKeyAlias=compute.17446274288301719340 -o StrictHostKeyChecking=yes -r /tmp/test.data [e-mail]:

您必须将类似的选项插入rsync，或将它们放在您的〜/ .ssh / config 文件中。

You'll have to plug similar options into rsync, or put them in your ~/.ssh/config file.
