推荐答案

如果您只想要自动备份，则有一种比采用成熟的编程语言更简单的方法:

If you just want automated backups, there is an easier way than resorting to a full-fledged programming language:

如链接中所示，以下命令就足够了.您可以将其放在statup-script/daemon中以常规频率执行:

As shown in the link, the below command would suffice. You may put it in a statup-script/daemon to execute it at regular frequencies:

备份:

lvcreate --size 100M --snapshot --name mdb-snap01 /dev/vg0/mongodb

还原:

lvcreate --size 1G --name mdb-new vg0
gzip -d -c mdb-snap01.gz | dd of=/dev/vg0/mdb-new
mount /dev/vg0/mdb-new /srv/mongodb
