Recovering data

Managing recovery

The AppAssure Core can instantly restore data or recover machines to physical or virtual machines from
the recovery points. The recovery points contain agent volume snapshots captured at the block level.
These snapshots are application-aware, meaning all open transactions and rolling transaction logs are
completed and caches are flushed to disk before creating the snapshot. Using application-aware
snapshots in tandem with Verified Recovery, enables the Core to perform several types of recoveries,
including:
• Recovery of files and folders
• Recovery of data volumes, using Live Recovery
• Recovery of data volumes for Microsoft Exchange Server and Microsoft SQL Server, using Live
Recovery
• Bare metal restore, using Universal Recovery
• Bare metal restore to dissimilar hardware, using Universal Recovery
• Ad-hoc and continuous export to virtual machines

Managing snapshots and recovery points

A recovery point is a collection of snapshots taken of individual disk volumes and stored in the repository.
Snapshots capture and store the state of a disk volume at a given point in time while the applications that
generate the data are still in use. In AppAssure, you can force a snapshot, temporarily pause snapshots,
and view lists of current recovery points in the repository as well as delete them if needed. Recovery
points are used to restore protected machines or to mount to a local file system.
The snapshots that AppAssure captures are captured at the block level and are application aware. This
means that all open transactions and rolling transaction logs are completed and caches are flushed to
disk before creating the snapshot.
AppAssure uses a low-level volume filter driver, which attaches to the mounted volumes and then tracks
all block-level changes for the next impending snapshot. Microsoft Volume Shadow Services (VSS) is used
to facilitate application crash consistent snapshots.
