For testing purposes, we've installed the Version 8.0.2_GA_5569.FOSS Dec 10, 2012 of ZCS on Ubuntu 12.04LTS.

Using a backup script "zmbak_v.0.8.sh" that was available online, we backup the data from /opt/zimbra which is around 14GB in size.

This is backed up onto another server. However, if we check the size of the backed up data "/opt/zimbra/" it is shown as 95GB.

When checked further in /opt/zimbra/ , it seen that the data/ldap/mdb/db/data.mdb is around 80GB. This is rather surprising, considering that the disk size on the source server is 80GB.

Please can someone shed some light on this.
