情况。通过 USB2 备份硬盘（是的，有点慢）
Udev-Rules 在 /media/partition-label 中挂载 /home-backup 分区（仅 1 个用户）。
/dev/sdb2 on /media/debianhome type ext4 (rw,nosuid,nodev,relatime,data=ordered,uhelper=udisks2)
` udev-rule 触发我创建的 systemd-unit。

/usr/local/bin/backup-home-skript 或我的 systemd-unit 有问题吗？我希望我提供了所有相关信息。
新的尝试。
rsync -aAXEovvvchxs --ignore-existing \
--exclude={iso-image,*cache*,*thumb*,rsync.log*,.*}
现在它被一个图像卡住了。
