建议新增【配置备份】功能

[apigx]

服务器上需要配置多个域名，配置过程是相当繁琐的事情。如果这个时候需要服务器资料搬迁。以当前BillionMail的工作量来说是相当巨大的。特别是配置了相当多Email模板的情况下。 因此我建议新增 配置备份 或者 全站数据备份的功能，方便用户把全站资料转移到新的服务器上。

Hello, you can stop BillionMail: bm stop, then back up the directory of the compressed BillionMail project, then upload the compressed file to the new server to decompress, install Docker, and start BillionMail: bm start

Hello, as the questioner said, the backup function is indeed a big problem for backup and recovery in the case of non-professional cases who are not familiar with docker. I hope the author can meet our needs for this.Thanks very much！
