Backup and Restore Overview
You backup your EcoStruxure BMS server data so that it can be restored after damage or loss due to hardware or software failures, security threats, or application testing.
The EcoStruxure Building Operation software provides backup and restore capabilities that preserve both configuration and historical data on an as-needed or periodic basis.
Backup
Backup is the process of copying and storing data so that the copy can be used to restore data if a loss occurs. You can also use a backup to revert to an older version. In the EcoStruxure BMS, you can perform backups on an all EcoStruxure BMS servers and their devices. EcoStruxure BMS server backups should take place during non-business hours.

Restore
Restore is the process of restoring data to an original or former state. Using Restore, you can revert to a previous snapshot of the EcoStruxure BMS server data despite any configuration changes made since the last backup. In the EcoStruxure BMS, Restore is a manual process designed to avoid the accidental overwriting of current EcoStruxure BMS server data.

Archiving Overview
Archiving is the process of preserving historical data, which is comprised of selected events and extended trend logs. For example, some facilities are required to maintain archives to comply with government regulations. Another example is in secure facilities where they must maintain records of who logged in or who changed setpoints. Archiving is not a backup function because archive data cannot be imported back into the system.

Retain Level
In the EcoStruxure BMS servers, variable values are primarily stored in flash memory in order to have their values survive power fail and server shutdown. However, values that are often collected are only stored in the SDRAM memory. This is done to protect the flash memory in the SmartX server.
