Reviewing the available backup methods

Supported Exchange Deployments: Standalone, SCCs/Failover Clusters, LCR (Active Copy only), CCR (Active Copy only)
IMPORTANT: Windows Server® 2008 supports Exchange Server 2007 SP1 or later; previous versions of Exchange 2007 are not supported. In a standard Exchange Server 2007 SP1 installation, there is an ESE client library (esebcli2.dll) in the Exchange Server Bin folder. The file version of esebcli2.dll is for Exchange Server 2007 SP1. However, if this library is not replicated from the Exchange Bin folder to the Windows Bin folder, an older version of the .dll file might be present in the Windows Bin folder. Plug‑in for Exchange uses the ESE client library that is available in the Windows Bin folder. If the older version of the library is contained in the Windows Bin folder, a backup or restore job might fail. If a failure occurs, save a copy of the ESE client library from the Windows Bin folder to a safe location, copy the ESE client library from the Exchange Server Bin folder to the Windows Bin folder, and run the backup or restore job again.
Supported Exchange Versions: 2007, 2010, and 2013

Managing transaction log files

If you use a Backup Type that supports transaction log file truncation, such as the Full and Incremental Backup types, the truncation of transaction log files is performed by the Exchange Server after the Plug‑in for Exchange informs it that the backup completed successfully. Additionally, when the truncation occurs depends on Exchange Server and whether it still needs the logs for additional purposes, such as replication; therefore, truncation might not occur immediately after a successful backup is completed.
IMPORTANT: VSS-based backups for non-Continuous Replication environments will truncate the transaction logs at the completion of Full or Transaction Logs-Only Backups. In LCR and CCR environments, log truncation is delayed by the Microsoft Exchange Replication Service until all necessary log files are replayed into the replica copy. Microsoft Exchange Replication Service deletes the backed-up log files both from the active and the passive copy log file paths after it verifies that the to-be-deleted log files have been successfully applied to the passive copy database and both the active and passive copy database check points have passed the log files in question.
