HowTo Use S3 as Backup Storage

HowTo - Zextras Export/Backup to External Storage

Create the mount point as zimbra user:

su - zimbra
mkdir /opt/zimbra/backup/zextras

Mount NFS backup storage:

vim /etc/fstab

# Add Zextras Backup store
ip.of.nfs.server:/backup/va-zimbra               /opt/zimbra/backup/zextras  nfs _netdev         0 0

Make sure the permissions are correct:

chown zimbra.zimbra /opt/zimbra/backup

Finally, initialize the Zextras Backup:

Zimbra Administration Console → ZeXtras → Backup → Initialize NOW

https://wiki.zextras.com/wiki/Zextras_Drive#Briefcase_Migration

Migrate all Briefcase data to Drive for all users:

for user in `zmprov -l gaa | grep -v -e galsync -e spam -e ham -e virus | sort`; do zxsuite drive doImport $user; done

To hide the Briefcase tab, uncheck it in the CoS.

The command zxsuite drive doImport has the attribute deleteSources true which deletes source files from the briefcase. You may do the import again with that parameter to clean the briefcases. Files already imported in Drive will not be modified if you don't use the overwrite true attribute.
