Exchange 2013 & TSM Backup

Hi ,

We are trying to configure TSM solution for Backup for exchange 2013 databases.

For DAG databases with IPless DAG configuration, DB backup is successful but the logs are not truncating.
We have the following errors on the Events:
1. Log Name: Application
Source: ESE
Date: 8/21/2021 10:19:01 PM
Event ID: 225
Task Category: ShadowCopy
Level: Information
Keywords: Classic
User: N/A
Computer:
Description:
Information Store - Default_Mailbox2 (14928) Default_Mailbox2: No log files can be truncated.
2. Log Name: Application
Source: MSExchangeRepl
Date: 8/21/2021 10:19:01 PM
Event ID: 2046
Task Category: Exchange VSS Writer
Level: Information
Keywords: Classic
User: N/A
Computer:

Description:
The Microsoft Exchange Replication service VSS Writer instance 29ff
-1c9c--b02b-062f*** has successfully completed the backup of database 'DB1'.
Database log truncation has been requested for this database. Log truncation will occur on the active copy after the next log generation is created. Log truncation will occur automatically on the passive copies after that log file is copied.

Exchange set up has 2 Prod nodes and 1 DR nodes. we tried removing the DR node and initiating backup still not luck to truncate the logs.

For default Mailbox database which is not added to DAG, log truncation is happening with the event 224.

Any thoughts is appreciated!
cheers
Priya

Hi @PriyaJayaraman-7005 ,

"For default Mailbox database which is not added to DAG"
Do you mean there are other servers that not joined to the DAG? And you also want to backup these servers?

Here is a related thread, see if this could help: https://social.technet.microsoft.com/Forums/ie/en-US/a6b2ccb3-7549-4e8e-beb8-bdaa7f376e53/log-files-not-truncating-with-windows-server-backup?forum=exchangesvradmin

Best regards,
Lou

Thanks ..The same article enlightened us!!! After migrating additional mailboxes to Exchange 2013 servers and the Database reaching the required checkpoint depth exchange started purging the transactions logs post successful backup.
