Microsoft Exchange Log Truncation
Microsoft Exchange is the industry's leading platform for e-mail, calendaring, and messaging services. To protect data from undesired deletion or modification, each change that is made to an Exchange Server database is recorded in transaction logs. These logs can be replayed to recover data that was removed or changed in the database. While this approach improves data protection, it has a downside. Since Microsoft Exchange database is constantly changing (as data is written and removed in the database), transaction logs grow over time. If not periodically removed, they will eventually fill up the disk and may crash the entire server.
NAKIVO Backup & Replication can create consistent backups of VMware and Hyper-V VMs as well as truncate transaction log files of Microsoft Exchange 2016, 2013, 2010, and 2007 servers. After creating a successful backup, NAKIVO Backup & Replication connects to your Exchange server, identifies which transaction log files have already been written to the database and removes (aka truncates) those log files.
Since your Microsoft Exchange database will be constantly changing (as new data is written to and old data is removed from the database), the transaction logs will grow and grow over time, and will eventually fill up the disk, if they are not removed. In order to remove the transaction log files, the database needs to be backed up. After creating a successful backup, NAKIVO Backup & Replication connects to your Exchange server, identifies which transaction log files have already been written to the database and removes (aka truncates) those log files.
As a result, NAKIVO Backup & Replication creates regular, application-consistent backups of your Exchange server and also removes the transaction log files so they don’t consume all free disk space on the server.
