Zimbra NG Backup is a Realtime Backup system, meaning that each and every change in the server is backed up as soon as it happens. This is possible thanks to Zimbra NG Backup's "[[Zimbra_Next_Generation_Modules/Zimbra_NG_Backup/RealTimeScan|RealTime Scanner]]" component.
 
 
 
== I already backup my Zimbra server by using a VM snapshot system. What's the difference between this and Zimbra NG Backup? ==
 
The main difference between a VM Snapshot manager and Zimbra NG Backup is the abstraction layer in which the two system operate: a VM Snapshot manager operates in the lowest layers, meaning that in case of a data loss you will be able to restore the whole server to a previous state, while Zimbra NG Backup operates in the Application layer by binding to the ''mailboxd'' service of Zimbra, meaning that based on the entity of the data loss you will be able to restore anything from a single item to entire domains.
 
 
 
== The [[Zimbra_Next_Generation_Modules/Zimbra_NG_Backup/Initialization|first SmartScan]] is taking a lot of time, is this normal? ==
 
In Zimbra Next Generation Modules the main backup system is the Real Time Scanner, which performs a high-level backup of each item and transaction without affecting mailbox availability in any way.
 
  
It's perfectly normal for the first [[Zimbra_Next_Generation_Modules/Zimbra_NG_Backup/Smartscan|SmartScan]] to take some time, as Zimbra NG Backup needs to parse, deduplicate, compress and store both data and metadata for all items in the system. Subsequent SmartScan operations will take much less time, and daily SmartScans will be even faster.

Closed accounts count towards the mailbox count for Zimbra NG Backup, as well as the admin account. Ham, Spam, Wiki and all the other System/Calendar Resources don't.
