Data backup requires the copying and archiving of computer data to make it accessible in case of data corruption or deletion. The backup and recovery of data is the process of backing up your data in the event of a loss and setting up secure systems that allow you to recover your data as a result. Without putting these systems in place, data recovery becomes difficult resulting in loss of information when the worst happens. Successful data backup systems are accomplished by using an offsite server or separate drives to store your massive amounts of information. It’s important for businesses to plan ahead and put data backup systems into place in case the worst happens, well before it happens. Hence, the backup and recovery of data is an essential part of running a successful business. While not sufficient for low recovery time objective (RTO) use cases, it can be used for a hot/cold restoration scenario where an RPO on the order of minutes is desirable.The purpose of backup is to solve three things for businesses and organizations during their daily operations: any computer or its operating system can crash anyone can make errors and disasters seem to happen when you least expect it or are least prepared for them.
#Data backup and restore full
Full system backups can also be run periodically (perhaps monthly) in order to capture a snapshot of the state of the server(s) should a catastrophe strike that requires a full system restoration.Ī live data backup is appropriate in order to frequently capture the state of the application data in order to provide rapid restoration of a previous state in case of a failure. Live Data Backups: Only Appian application data directories listed in the live data backup procedure, the RDBMS data, and, optionally, the log files are backed up.Ī full system backup is appropriate when upgrading Appian or applying a patch/hotfix.

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 data, 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 page outlines the backup process for Appian documents and data.
