Despite all precautions, it may happen that you want to recover from data loss or want to go back to an older state of the E2E Bridge. In this case, you may want to load a backup of a previous state of the E2E Bridge.

Taking a Bridge Backup

...

Depending on the operating system, an E2E a Bridgeinstallation consists of the following components:

Operating System	OS Specific Data	Bridge Folders
Windows	Windows registry entry	E2E Bridgeprogram directory E2E Bridgedata directory
Linux	scripts and configuration files from directory /etc

The operating system specific data and the E2E Bridge the program directory can be recovered by performing an E2E a Bridge installation of the very same version (see Loading a Bridge Backup of an E2E Bridge below). Nevertheless, you can take a filesystem backup of these items.

Whereas, the E2E Bridge data directory cannot be recovered from a Bridge installer and needs to be backup-ed from the filesystem. To do so, you can use any tool of your choice. The E2E Bridge and all services may be up and running You do not need to shutdown services or the Bridge while you are taking the backup.
If the backup takes a big amount of disk space, you may leave out the following folders and files:

...

The mentioned files may contain helpful information but are not necessary to recover and operate the services on the E2E Bridge. Especially the logfiles may grow by the time and may lead to big backup files.

One Filesystem Backup

If you have backup-ed the complete Bridge installation with one filesystem backup, you can recover your Bridge installation as follows:

1. Stop your E2E Bridge.
   Stop all running services, the proxy server (if necessary), and the E2E Bridge system service.
2. Replay the filesystem backup of your E2E Bridge files on top of the current installation.
3. Start your E2E Bridge.
4. Start the services.
   All services that do not have flag Automatic restart set, need to be started manually.

...

If you have backup-ed the E2E Bridge data files separately with a dedicated filesystem backup, you can recover your Bridge installation as follows:

1. Stop your E2E Bridge.
   Stop all running services, the proxy server (if necessary), and the E2E Bridge system service.
2. Replay the filesystem backup of your E2E Bridge data files on top of the current installation.
3. Re-run the E2E Bridge installer of the target Bridge to recover the E2E Bridge program files and operating system specific data.
   The installer has an option that allows you to directly start your Bridge automatically after installation.
4. Start the E2E Bridge, if not already done with step 3.
5. Start the services.
   All services that do not have flag Automatic restart set, need to be started manually.
