Hi, can you check the contents of the file in question?
/opt/zimbra/backup/sessions/full-20080308.060007.994/a
ccounts/e08/bc6/e08bc6bd-d835-4262-8a56-7365c3313789/meta.xml
Does it exist and if so, does it contain valid-looking XML data? Does it have correct permission? (readable by zimbra user)
Here's what a sample file looks like:
<?xml version="1.0" encoding="utf-8"?>
<backupMetadata xmlns="urn:zimbraBackupMeta" version="7.0">
<accountBackup zimbraId="041760fd-24d9-40ef-b411-f46b3eef376a" email="user@domain.com" mailboxId="12" startTime="1206725960244" endTime="1206725960351" redoSeq="1" server="server.domain.com">
<volumes>
<volume id="2" path="/opt/zimbra/index/0/12/index">
</volume>
<volume id="1" path="/opt/zimbra/store/0/12/msg">
</volume>
</volumes>
</accountBackup>
</backupMetadata>
