Zimbra Backup Plus - FAQ

Zimbra Backup Plus - FAQ

How do I set up a working backup infrastructure with Zimbra Backup Plus?

Simply follow this guide: Zimbra Backup in Open Source.

Does Zimbra Backup Plus use a "Full+Incremental" backup technique?


Zimbra Backup Plus 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 Backup Plus's "RealTime Scanner" component.

I already backup my Zimbra server by using a VM snapshot system. What's the difference between this and Zimbra Backup Plus?

The main difference between a VM Snapshot manager and Zimbra Backup Plus 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 Backup Plus 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 first SmartScan is taking a lot of time, is this normal?

In Zimbra Suite Plus 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 SmartScan to take some time, as Zimbra Backup Plus 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.

How do I migrate my Zimbra Open system to a new server?

Take a look to our Migrate Zimbra page to get started.

Are emails downloaded via POP3 and deleted from the server backed up?

Yes, as long as those are processed by the RealTime scanner before a client deletes the items.

Do I need a license for every mailbox in my server?

The number of licensed mailboxes must be equal or higher than the number of maiboxes in your server. This means you need a license for every REAL mailbox in your server (see next question).

I have several closed accounts on my server, along with the ham, spam, wiki, admin etc accounts. Do I need a license for those accounts too? (asked by LeeLeman on the forums)

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

What happens if I import data to an existing account? Will the current data be deleted?

No data will be deleted. All restore modes perform only "ADD" operations on the mailbox.
