interesting, my knee jerk reaction is That I would still script out for disaster recovery, an d keep performing native backup and disaster recovery for SQL server regardless of the high level sales literature that implies it's the best solution since sliced bread.
I read the Dell corporate fluff at these two links:
http://www.appassure.com/server-backup-replication-and-recovery/
http://www.appassure.com/downloads/Dell_AppAssure_Specsheet.pdf
and it appears to be a server solution that happens to try to take care of SQL
Recovery Assure™
Detects the presence of Microsoft Exchange and SQL and its
respective databases and log files, then carries out a nightly test to
confirm that database application backups are fully recoverable. If any
backup fails this test, a notification is automatically sent so you can
resolve the problem immediately
and version support:
SQL Server support
• MS SQL Server 2012, 2008 R2, 2008,2005
• MS SQL clusters based on Microsoft Cluster Server
