I使用命令
docker exec -t $CONTAINER_ID gitlab-backup create创建备份。恢复时，我遵循文档的官方说明。
docker exec -it <container_id> gitlab-ctl stop puma
docker exec -it <container_id> gitlab-ctl stop sidekiq
docker exec -it <container_id> gitlab-backup restore BACKUP=<backup_name>
在还原过程中，在恢复Postgres表的末尾显示错误（

试图在docs.gitlab
使用Docker swarm对GitLab实例进行修复有时可能导致GIT存储库未正确恢复，即使数据库和其他组件已成功恢复。
似乎问题是，当您使用GitLab备份/还原过程时，GIT存储库无法正确恢复。以下是您可以遵循的一些步骤进行故障排除并解决此问题：
如果您使用的是Docker，请确保正确安装存储库数据的卷。如果由于量错误而无法正确备份数据，则不会恢复。
3。使用正确的还原命令：恢复后，需要正确指定备份ID。例如：
(<backup-id>_gitlab_backup.tar)(usually /var/opt/gitlab)带有容器的名称，并使用备份的正确ID。
4。匹配GitLab版本：您还原的GitLab版本必须匹配创建备份的版本。不匹配的版本可能会导致恢复过程中的问题。
5。监视错误：在还原过程中，检查日志是否有任何错误或警告。这些通常指出出了什么问题。
6。评论配置：确保正确设置了GitLab配置（例如
docker exec -t <container_name> gitlab-backup restore BACKUP=<backup-id>
中的存储库路径）。这里的设置不正确可能导致还原过程跳过存储库。
7。检查权限：如果文件还原，但Gitlab无法访问它们，则可能是权限问题。确保将正确的所有权和权限应用于还原的数据。如果您经历了这些步骤，并且仍然不起作用，请随时分享更多细节。例如，任何特定的错误消息或您的设置（例如Docker swarm或独立安装）。这可能有助于缩小问题！
