cd /opt/zimbra/mailboxd/webapps/service/zimlet/
mv com_zimbra_backuprestore com_zimbrabackuprestorehold
in one window: tail -f /opt/zimbra/log/mailbox.log
in the other:
su - zimbra
cd zimlets-network
zmzimletctl deploy com_zimbra_backuprestore.zip
zmmailboxdctl restart
Reason I want you to check the log is because there are two modes of deploy when using zmzimletctl. By default it works in async mode. The tool makes a soap request to the mailboxd, which will spawn a thread and finish deploying. The command line tool does not block while the whole operation is finished. The obvious side effect is that the CLI won't know the result of the deploy. The new message for this is "INFO: Deploy initiated. Check the servers mailbox.log for the status." The second mode of operation is with the -l (lima) flag. When using the this mode, CLI will wait and see the end of the deploy and report any error.
