We're currently using AppAssure to back up the SQL servers (2012/2014). It uses VSS snapshots. All databases are in simple recovery mode. Do I need to bother backing up the drive that contains the ldf files or is it enough to just back up the mdf files and let the log files recreate during a full restore?
SQL Writer Service explains how VSS can be used to take application consistent snapshot backups of the database files directly. It says it does not support log backups, which is why I asked this question.
Snapshot Backups are a feature of SQL server that allow hot backups without doing traditional dumps.
