现在问题来了。我有一个带有 Nextcloud 实例的 Ubuntu 16.04 服务器 (NUC)。我有树莓派通过 SSH 连接到 NUC。我已经在 Raspberry Pi 上安装了 Rsnapshot 并创建了 cron 作业，它可以工作，但仅适用于 /etc/。/ownclouddata 文件夹已同步，但它是空的。我怀疑这是所有权问题（使用 www-data），但我非常不愿意在没有适当帮助的情况下搞砸所有权。所有这些概念对我来说仍然很模糊......

有什么帮助？？？

这取自我在 Pi 机器上的 rsnapshot.conf 文件。

LOCALHOST
backup [email protected]:/media/data/ownclouddata/ nuc/
backup [email protected]:/etc/ nuc/
ssh rsnapshot

我已经启动并运行了 Rsnapshot ......

# LOCALHOST
backup  /home/          localhost/
backup  /etc/           localhost/

但我想备份我的整个 SSD(sdb) 而不是我的外部 USB 驱动器 (sda)...

Filesystem      Size  Used Avail Use% Mounted on
udev            1.9G     0  1.9G   0% /dev
tmpfs           385M   40M  345M  11% /run
/dev/sdb2        30G  8.4G   20G  30% /
tmpfs           1.9G   20K  1.9G   1% /dev/shm
tmpfs           5.0M     0  5.0M   0% /run/lock
tmpfs           1.9G     0  1.9G   0% /sys/fs/cgroup
/dev/sdb4        69G   53M   66G   1% /home
/dev/sdb1       1.9G  4.5M  1.9G   1% /boot/efi
/dev/sda1       7.3T  4.1T  2.9T  59% /media/data
tmpfs           385M     0  385M   0% /run/user/1000

我的 rsnapshot.conf #LOCAHOST 文件应该是什么样子？？？

感谢您在这里的帮助...

我现在使用桌面上的 rsa 密钥对连接到我的 Ubuntu 服务器！但我不知道该怎么做才能从我的笔记本电脑连接到服务器！！！我需要创建另一个密钥对吗？我可以简单地将私钥从一台计算机复制到另一台计算机吗？

这里的最佳做法是什么？

谢谢你的帮助！！！！

我应该怎么做才能修复此语言环境设置警告？我已经在网上搜索过，但我是新手，我有点迷茫......
