可否请开发者在Gitea里面增加增量与差量备份模式？对于Postgresql，MySQL数据库软件是否有备份方法不清楚，Gitea默认备份方法是全量模式。每次迁移导入希望能把不同的部分再导入另一台机器。本人并不是计算机专业学生，工科生，使用Gitea是为了版本管理。如有说的不妥的地方，请指正与轻喷。
Can developers add incremental and differential backup modes in Gitea? For PostgreSQL,MySQL, it is unclear whether database software has a backup method. Gitea’s default backup method is full volume mode. Each migration import hopes to import different parts into another machine. I am not an professional postgradute majoring in computer science. I use Gitea for version management. If there is anything wrong, please correct and say nicely.
