The Rapid Recovery Core can instantly restore data or recover machines to physical or virtual machines from recovery points. The recovery points contain agent volume snapshots captured at the block level. These snapshots are application aware, meaning that 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:
Live Recovery is a feature of restoring data in Rapid Recovery Core. If your protected machine experiences data failure of a non-system Windows volume, you can restore data from a recovery point on the Rapid Recovery Core. Selecting Live Recovery in the Restore Wizard allows users to immediately continue business operations with near-zero downtime. Live Recovery during restore gives you immediate access to data, even while Rapid Recovery continues to restore data in the background. This feature allows near-zero recovery-time, even if the restore involves terabytes of data.
Rapid Recovery Core uses unique block-based backup and recovery technology that allows full user access to target servers during the recovery process. Requested blocks are restored on-demand for seamless recovery.
Live Recovery applies to physical and virtual machines protected by Rapid Recovery Core, with the following exclusions:
Live Recovery lets you instantly restore physical or virtual servers directly from the backup file. When a non-system volume is being restored, Rapid Recovery presents the volume metadata to the Operating System instantly, making that data available on demand. For example, if the database volume of Microsoft Exchange is corrupt, Live Recovery can restore the volume, database, and Exchange services in minutes.
This feature provides the fastest method of recovering large quantities of data with minimal downtime. Users can immediately continue business operations.
Once Live Recovery begins, the restored volume and its contents become instantly available. Rapid RecoveryCore continues to restore the data in the background, even though the volume, its data, applications and services are already back in production. If specific data is requested, the background process prioritizes the restoration of this data immediately. This powerful functionality allows even the most stringent service-level agreement to be met.
Once you start Live Recovery, metadata (directory structure, security descriptors, NTFS file attributes, free space map, and so on) of the target volume is quickly restored on the protected machine. Thereafter, the volume and its contents become available to the system. The Rapid Recovery Agent begins restoring data blocks from the Rapid Recovery Core server, writing the blocks to the target volume.
Requests for data that has not yet been restored are immediately answered, with the requesting program or system unaware that the blocks were just restored.
Rapid Recovery protects your data on Windows and Linux machines. Backups of protected agent machines are saved to the Rapid Recovery Core as recovery points. From these recovery points, you can restore your data using one of three methods.
From the Rapid Recovery Core Console, you can restore entire volumes from a recovery point of a non-system volume, replacing the volumes on the destination machine. You can do this for only Windows machines. For more information, see About restoring volumes from a recovery point.
You cannot restore a volume that contains the operating system directly from a recovery point, because the machine to which you are restoring is using the operating system and drivers that are included in the restore process. If you want to restore from a recovery point to a system volume (for example, the C drive of the agent machine), you must perform a Bare Metal Restore (BMR). This involves creating a bootable image from the recovery point, which includes operating system and configuration files as well as data, and starting the target machine from that bootable image to complete the restore. The boot image differs if the machine you want to restore uses a Windows operating system or a Linux operating system. If you want to restore from a recovery point to a system volume on a Windows machine, see Performing a bare metal restore for Windows machines. If you want to restore from a recovery point of a system volume on a Linux machine, see Performing a bare metal restore for Windows machines.
Finally, in contrast to restoring entire volumes, you can mount a recovery point from a Windows machine, and browse through individual folders and files to recover only a specific set of files. For more information, see Restoring a directory or file using Windows Explorer. If you need to perform this while preserving original file permissions (for example, when restoring a user’s folder on a file server), see Restoring a directory or file and preserving permissions using Windows Explorer.
The topics in this section describe information about restoring data on physical machines. For more information on exporting protected data from Windows Machines to virtual machines, see Exporting protected data to virtual machines.
You can restore the volumes on a protected machine from the recovery points stored in the Rapid Recovery Core. In AppAssure 5.4 and later, this process uses the Restore Machine Wizard.
You can begin a restore from any location on the Rapid Recovery Core Console by clicking the Restore icon in the Rapid Recovery button bar. When you start a restore in this manner, you must specify which of the machines protected on the Core you want to restore, and then drill down to the volume you want to restore.
Or you can go to Recovery Points page for a specific machine, click the drop-down menu for a specific recovery point, and then select Restore. If you begin a restore in this manner, then follow this procedure starting with Step 5.
If you want to restore from a recovery point to a system volume, or restore from a recovery point using a boot CD, you must perform a Bare Metal Restore (BMR). For information about BMR, see Understanding bare metal restore for Windows machines, and for prerequisite information for Windows or Linux operating systems, see Prerequisites for performing a bare metal restore for a Windows machine and Prerequisites for performing a bare metal restore for a Linux machine, respectively. You can access BMR functions from the Core Console as described in the roadmap for each operating system. You can also perform a BMR from the Restore Machines Wizard. This procedure will direct you at the appropriate point in the wizard to the procedure About performing a bare metal restore using the Restore Machine Wizard.
