在 Ubuntu 18.10 中使用备份时出错（Deja Dup）

Question

我的最终目标是对系统（如时间机器）进行完整备份，并在发生灾难时使用它重新安装它。中间目标是在一天中多次备份所有工作区域。

好吧，我遵循了您的所有建议：使用 apt-get 删除了 deja-dup 安装的备份没有备份根目录（尚未应用建议的补丁来合并 /）

但结果总是一样的。看起来有一些损坏的数据：注意最后的消息总是一样的！！！！

    return ufn(unicode(e).encode('utf-8'))
 UnicodeDecodeError: 'ascii' codec can't decode byte 0xe2 in position 37: ordinal not in range(128)

现在的配置是：

Folder to save: /etc /dev /run /bi /sbin /snap /sys /proc /opt /media /root /lib64 /lib /srv /var /usr /mnt
Folders to ignore: Trash, /backup, /git, /neo4j, /sys_backup /home
Storage location: Local folder - /sys_backup

卸载 deja-dup 的 snap 版本，安装非 snap 版本。使用 deja-dup 备份主目录中的特定文件夹（不是所有的 / 或 ~/）。

sudo snap remove deja-dup # remove the snap version
sudo apt-get update # update the software database
sudo apt-get install deja-dup # install deja-dup

安装timeshift并使用它来备份系统/操作系统文件...

最接近类似 Windows 的还原点是使用Timeshift. 我用它来将快照保存到外部 USB 硬盘驱动器。虽然它可以，但它通常不用于备份您的 /home 目录，仅用于系统级别的更改。使用Backups(Déjà Dup) 备份 /home 文件。

Timeshift is a system restore utility which takes snapshots
of the system at regular intervals. These snapshots can be restored
at a later date to undo system changes. Creates incremental snapshots
using rsync or BTRFS snapshots using BTRFS tools.
