exchange backup can be done using free windows server backup and also Microsoft backup software called data protection manager (DPM) or third party backup solutions. Here is the information of WIndows server backup 1. it is VSS backup only 2. start the backup locally only but data can be stored remotely 3. Database will be backup on active mailbox server only no passive db 4. if you want to truncate logs, you have to run vss full backup on that volume.

See this for some background and see link in sub sections for restores/backup - http://technet.microsoft.com/en-us/library/dd876874.aspx Different steps are required for different types of restores, i.e mailbox/database/servers restores. It depends what failure you have and are recoveing. The backup/restore procedures will be different too, depening on the type of server roles, i.e HUB/CAS/MBX. Understand these and there is some information on this on technet. The backup/restore will also depend on what product/techinology yoyoure using and what your stragtegy is. You may want to not backup your Mailboxes if your using say 4 DAG across different sites. Sukh

The backup and restore functions of Exchange's ESE provide three types of backup capabilities: full, incremental and differential. Combined with Windows Server 2003's VSS, Exchange Server 2003 also supports snapshot backup types (more on this type of backup later). A full backup (also called a normal backup) backs up the entire directory or information store and allows you to restore it from a single backup. An incremental backup backs up just the changes since the last full or incremental backup. These are simply the transaction logs that have accumulated since the last full backup. Restoring incremental backups requires the original full backup plus all the incremental backups Exchange 2007 SP2 & Windows 2008 Server Backup…---> Now that Exchange 2007 SP2 has been released, it gives the ability to backup Exchange 2007 SP2 using Windows Server Backup (WSB). Let me mention a few points before you jump into the conclusion of using it for backing up exchange. Windows Server Backup is not installed by default on 2008 servers. It can be installed by using Server Manager -> Add Features -> Windows Server Backup. WSB can only backup at a volume (drive) level. Backups can be stored to a local drive or a network drive (Local drive shouldn’t be the drive that you have selected to backup or a system drive). Only disk backup is available, no option for tape. Only copy or full backup of exchange can be done. Copy backup doesn’t flush the logs whereas a full one does. Cannot do incremental backups of exchange. If you run a “Backup Once” job, you can select just the drives that have exchange databases & logs. If you want to run a scheduled job, system drive is included by default and can’t be taken off. Database will be checked for consistency, backed up & logs flushed. You can only backup active exchange servers, so passive node of ccr cluster cannot be backed up. During exchange restore, new log files will be replayed & database will be brought to the latest state. You can deselect replay of logs during restore, if you want. In short, it can backup & restore. It is nothing like the old NTBackup! ---> http://www.howexchangeworks.com/2009/09/exchange-2007-sp2-windows-2008-server.html
