The last store operation date reported on the server does not match the date stored locally on the client. If connected to the replication server it is likely that the replication was done before the last store operation from the client to the primary server. Hence, the replication is out of date. If connected to the primary server it is likely that the previous backup was done from another machine.
Processing continues.
Contact the TSM server administrator. Restoring from an out of date replica may lead to loss of data. If the primary server cannot be recovered, a full backup to the replica may be appropriate. If connected to the primary server, the message can be ignored.
