I want to make a mirror of the ethereum private chain, see the relevant information, and finally feel the need to understand the basic principles of Docker, perhaps the subsequent operation will be more smooth

Docker needs to have a corresponding mirror locally before running the container, and if the mirror does not exist locally, Docker will download it from the mirrored repository (by default, the warehouse in the Docker Hub Publ
Since SQL Server 2000, you've been able to create an alternate server, transfer logs, and back up and store by using replication-but now Microsoft has introduced a built-in tool that can automate error recovery. Database mirroring is a new feature of SQL Server 2005 that allows you to mirror the contents of a database in one SQL Server to another SQL Server. It also allows you to make error recovery by mirroring

A brief introduction of mirroring
1. Introduction
Database mirroring is the move of database transactions from one SQL Server database to another SQL Server database in a different SQL Server environment. Mirroring is not directly accessible, it can be accessed only in the case of error recovery.

13.1 Preparing Database MirroringThe following experiment illustrates the process of configuring database mirroring.The existing environment is as follows:
Server name

Brief introductionFor small and medium-sized businesses or websites that choose Linux as an application platform, they often face problems with remote backup of data or mirror images of the site, although there are commercially available backup and mirror products to choose from, but the prices of these products are often too expensive. Therefore, how to use free software to efficiently realize remote backup and website mirror image becomes a topic worthy of discussion.The simplest way to make a
