By default, Zimbra Network Edition automatically:

• Does full backups (including LDAP) weekly
• Incremental backups (user data diffs) nightly
• Retains data for one month

If you have the disk space for it, it's recommended to leave this configuration. Otherwise you can update it with zmschedulebackup.

For restore operations, you'll be using zmrestore or the web admin interface.

Change the backup location from the default /opt/zimbra/backup:

zmprov mcf zimbraBackupTarget "/ZimbraBackup"

The ZeXtras Suite offers automated backups.

Here is a simple method that uses an extra disk drive as the target (Parts 1 and 2):

Take a snapshot before installing patches if you are in a virtualized environment.

This does not work with Zimbra 9 OSE (Zextras Build)

cd ~
mv -f zcspatch zcspatch.old
mkdir zcspatch && cd zcspatch
wget https://files.zimbra.com/downloads/8.8.6_GA_HF/zcs-patch-8.8.6_GA_HF_108839.tgz

tar -xzvf zcs-patch-*
cd zcs-patch-*
./install_patch.sh

su - zimbra
zmcontrol restart

Take a snapshot before installing upgrades if you are in a virtualized environment.

This takes some time and may require a couple of reboots

If you see an error pertaining to Required Core package zimbra-core not found, make sure you are using the correct installer package.

1. Block port 25 inbound in the firewall
   1. Also block HTTP and HTTPS for major upgrades
2. Update the host OS (reboot)
3. Install any new prerequisites
4. Download the latest version of Zimbra
   • Network: http://www.zimbra.com/downloads/zimbra-collaboration
   • OSE: https://www.zimbra.org/download/zimbra-collaboration
5. Extract the tarball
6. Change into the extracted folder
   • cd zcs<tab>
7. Execute the installer
   • ./install.sh
8. Reboot
9. Reopen SMTP/HTTP/HTTPS ports in the firewall

mv -f zcsinstall zcsinstall.old

You will want to use custom partitioning so that the Zimbra installation is on a large, expandable (LVM) partition (/opt).

Make sure you have at least a 15GB partition or you may have problems upgrading down the road.

If you mount a separate disk or partition for Zimbra, mount it at /opt/zimbra.

See Centos 6 x64 Minimal Install.

Assure that name resolution is working to the Zimbra host.

  • A record
• Reverse
  • PTR record
• Mail Exchanger
  • MX record

vim /etc/hosts

vim /etc/hostname

See also Static IP Address.

See also Zimbra Firewall

Here we disable the firewall so it doesn't cause problems during installation. You should re-enable some firewall after the initial installation and configuration.

iptables -nL

service iptables stop
service ip6tables stop

apt-get update && apt-get -y dist-upgrade && apt-get -y autoremove && reboot

/etc/fstab example:

# add /opt/zimbra/store
/dev/disk/by-uuid/a398b8ef-16b7-42f5-bba5-96e6249af038 /opt/zimbra/store ext4 defaults,noatime,nodiratime,dirsync 1 2

# add /opt/zimbra/store2
/dev/disk/by-uuid/ead24e00-7be4-4e42-be1a-66e37925640c /opt/zimbra/store2 ext4 defaults,noatime,nodiratime,dirsync 1 2

• With Zimbra 8, there is now an 80GB (sparse) database file that takes a long time to copy

service zimbra stop
rsync -avr --delete /opt/zimbra /opt/zimbra.bak

Once this backup has been created, it will subsequently be much quicker, assuming you have disk space to spare for the backup. You did check that first, right?

1. Install a separate hard drive in your Zimbra server
2. Connect the new hard drive to a separate disk controller
   • This is important if you have a RAID controller for primary storage
   • You can usually use the controller integrated on the mainboard
3. Partition the new drive with one large partition
   • Use GPT partition table for drives over 2GB
4. Format the new partition
   • Consider using the XFS filesystem
     • mkfs.xfs /dev/sdx1
5. Mount the new drive automatically at boot
   • blkid shows UUID
   • Modify /etc/fstab
     • UUID=<UUID> /opt/zimbra/backup xfs defaults 1 0
   • mount -a

Zimbra Network Edition has a default backup location /opt/zimbra/backup. It may be more convenient to use another location.

Global:

zmprov mcf zimbraBackupTarget "/ZimbraBackup"

Per server:

zmprov ms `zmhostname` zimbraBackupTarget /tmp/backup
