![]() In those cases, the data only needs to be backed up once from one of the servers. When running in a system with multiple application servers, some of these directories are shared between servers. The locations of application data components are listed in the following table. The folders containing this application data should be backed up at the same time. Appian application dataĪpplication data comprises files stored on the server that are referenced by Appian engines, including documents stored in the document management system, archived processes, search indices, the keystore file, data in the data server, and other data files. ![]() Otherwise, you might encounter synchronization issues. This ensures that during recovery the system's data snapshot is synchronized and consistent. When scheduling a script to backup the Appian engines, external databases must be backed up at the same time. Appian application data (documents, archived processes, and other files)Įach of these components is backed up separately, yet all backups must occur simultaneously so that data can be restored in a consistent state.There are two primary data components that should be backed up: Instead, the High Availability configuration should be used for disaster recovery with low RPO requirements. While backups are an approach to achieving an RPO on the order of hours, it is not the preferred method for achieving very low RPOs (minutes). This concept is referred to as the Recovery Point Objective (RPO). If you back up nightly, the most data you might lose is one day's worth. Using backups to preserve data when a catastrophic event occurs requires more frequent backups that ultimately depend on how much data you are willing to lose when restoring the data. The frequency of conducting backups depends on the use case.įor data archival and auditing purposes, backing up weekly or even monthly may be sufficient. ![]() The main reasons for backing up Appian installations and related data are for data archival and auditing purposes and as a protection against catastrophic events. This topic outlines the backup process for Appian documents and data.
