You don't say what backup program you are using or what type of backup you are performing.

Hi, we are using EMC Networker and we are taking weekly full back and daily incremental. following event is logged in the passive node Event ID: 2137 Description: Log truncation request to the Information Store using RPC has failed for storage group 'xyx\StorageGroup'. Error code: 4294966264. wasay13

Hi wasay13, Please restart the MsExchangeReplication service on both CCR nodes first and backup again to see whether it works. If it doesn't work, please temp disable Anti-virus application if you have one. If it still doesn't work, please reseed the CCR passive node: How to Seed a Cluster Continuous Replication Copy http://technet.microsoft.com/en-us/library/bb124706(EXCHG.80).aspx Frank Wang Forum Support Please remember to mark the replies as answers if they help and unmark them if they provide no help.
