File system replication

Overview

Filesystem replications refer to a master filesystem - any files that are written to the master filesystem are mirrored to the filesystem replication. This serves as a simple and cheap backup solution and allows to provide files in different locations for flexible production planning. When files are accessed in a decentralized multi-server environment, the server will access the files from the filesystem with the fastest access.

Any creation, deletion, or modification of a file is first executed on the master filesystem. Then, an entry is queued in the EventTask list for each replication filesystem. Each application server queries the EventTask list and executes the file operations that refer to replication filesystems the application server is responsible for.

It is important to know that, besides the replication filesystem keys, it is also necessary to create an entry for the master filesystem. This master filesystem has to be declared as „master replication“ in the filesystem configuration.

Details

• Filesystem: selection of the filesystem that should be replicated.

• ID: unique alphanumeric key of the filesystem replication.

• Description: visible name of the filesystem replication (in all defined system languages).
