my Volumes is not carefully formatted，how to recovery?

Have you unintentionally formatted one of your Block Storage Volumes? If so, there's no way to recover the data. In the future, I'd recommend making a copy of your Volume as a backup, or taking a backup in other ways. For example, you can use mysqldump to make a backup of a MySQL or MariaDB database.

For other data, we have a guide with suggestions on how to pick the best backup utility.
