An important issue is addressed in the latest Trilead VM Explorer release 4.1.004
Trilead announced …
New support for ESX/ESXi 5.1 838463 – which keeps current with the latest changes but more importantly – Implementation of VMware’s workaround to avoid VDDK library issue, which could compromise incremental backups as described in the known issue from VMware.
http://www.vmware.com/support/developer/vddk/VDDK-510-ReleaseNotes.htmlThis problem can occur with all VM Explorer versions. Please update VM Explorer as soon as possible and update also ESX/ESXi 4.0 servers (if present in your infrastructure) as well, because these servers suffer from another problem related to incremental backups as described in VMware KB 1021607 http://kb.vmware.com/kb/1021607
If you do not update VM Explorer, Trilead suggest you do disable incremental backup/replication features and configure full backup/replication instead.
