Zimbra facts
A Zimbra account or a TGZ export is hard to open without a Zimbra server. Zimbra Backup Tool loads either one on Windows, shows a preview of every data file and writes the mail out in formats other apps accept.

4Mail tied to one platform
Zimbra TGZ exports and cloud mailboxes tie mail to one platform. A backup tool unlocks it. Mail leaves the server as plain files that any client opens, even after the Zimbra system is gone.

Core features
Open, scan, filter and save.
Open
Launch Zimbra Backup Tool, click the Open tab and load Zimbra data from an email account or a server tab.
Load a login or a TGZ file, add multiple profiles at once, and back up with no file size limits.
Scan
The software scans the data and builds a complete preview of every file. Double-click any email to see it with its attributes.
The source gets a full scan, the Manage tab lists all accounts, and several accounts can be viewed together.
Filter
Set the date, time or year of mail to keep. The advanced search filter finds selected emails from the entire Zimbra database.
Date and time limit the period, year narrows an old archive, search finds a specific thread, and attachments and addresses can be sorted and exported.
Save
Select the data backup option and click Save. Output goes to the desktop by default or to any folder that is browsed to.
Choose from 20+ file formats or 100+ web applications, including Gmail, AOL, Office 365, iCloud, Lycos, Webmail and WorkMail. File naming options keep files in order, and phone numbers and addresses can be exported alone.
Result
Open the output folder to see mail with its original formatting. Naming options keep the files in a clear order.
Output lands on the desktop or a chosen path with exact formatting retained. For a full server move see the Zimbra Migration Tool, and for a file-only job try the Zimbra Converter.

One account, a TGZ file or a list of profiles: Zimbra Backup Tool handles all three. Test your job in free demo before you buy.

Before purchase
Admins can keep a TGZ export, yet reading it needs the Zimbra platform. Here is the TGZ route next to Zimbra Backup Tool.
| Task | TGZ export alone | Zimbra Backup Tool |
|---|---|---|
| Price | Free in Zimbra | $99 one time |
| Keep a TGZ file | Built in | Also possible |
| Open mail on Windows | Needs a Zimbra server | Direct from the file |
| Formats | TGZ only | 20+ formats |
| Preview | Not offered | Double-click preview |
| Selected mail | Entire account only | Filter then save |
| Other mail apps | Manual import | 100+ web applications |
| Several profiles | One by one | Managed together |
Rows tinted green are where a TGZ export is enough.
A TGZ file keeps a Zimbra copy alive. To move it elsewhere, read Zimbra to PST converter.

After searching a lot on technical forums on how to take Zimbra webmail backup, I come across this Zimbra Cloud Mail Backup Wizard that enables me to download my Zimbra data file without any error or external support. Thanks for this fantastic solution.
This Zimbra mail server backup wizard deserves a 5-star rating on its excellent performance while backing up Zimbra. The advanced search filter helps me find my important emails, and the best part of the software is that it allows to save selected emails files.
I tried the demo edition of Zimbra backup tool, and believe me. It is one solution with multiple benefits. Users can directly transfer their data files to 100+ mail applications, and the software's graphical interface is easy to use.
Best practice
Saved mail is only useful if it opens later. These four habits protect your Zimbra archive.
Back up before the server goes
Save a copy before a Zimbra server is retired, upgraded or moved.
Open a sample file
After saving, open a handful of messages. Confirm folders, photos and attachments came across.
Keep PST and PDF
Repeat the backup with a second format. PST for Outlook and PDF for reading anywhere is a common pair.
Store a copy elsewhere
Keep one copy on a home drive and one on a USB stick or NAS, named by address and date.
