These release notes provide information about the Dell Data Protection | Rapid Recovery™ release, build 188.8.131.52.
Dell Data Protection | Rapid Recovery software delivers fast backups with verified recovery for your VMs and physical servers, on-premise or remote. Dell™ Rapid Recovery is software built for IT professionals who need a powerful, affordable, and easy-to-use backup, replication, and recovery solution that provides protection for servers and business-critical applications like Microsoft® SQL Server®, Microsoft Exchange, and Microsoft SharePoint®. Using Rapid Recovery, you can continuously back up and protect all your critical data and applications from a single web-based management console.
Rapid Recovery release 6.0.2 is a minor release, with enhanced features. See Enhancements.
Previously named AppAssure, Rapid Recovery has been rebranded in release 6.0.x to reflect the next step in its evolution. The new name applies to Rapid Recovery Core, as well as the Rapid Recovery Agent software you can install on machines to protect their data.
Some other components have been rebranded for consistency. For more information on rebranding, see the Enhancements topic in Rapid Recovery 6.0.1 Release Notes.
For Rapid Recovery 6.0.x users that want to replicate on-premise Cores to the cloud, a new Azure VM is available. For more information, see the Dell Data Protection | Rapid Recovery Replication Target for Microsoft Azure Setup Guide available on the Dell Software website. There is an upgrade path for users of AppAssure Replication Target for Azure (release 5.4.3)
If you are using AppAssure Replication Target for Azure (release 5.4.3) and plan to upgrade your on-premise source Core, you can upgrade your target Core on Azure. See the updated Setup Guide for upgrade information.
Rapid Recovery 6.0.2 is a minor release, with enhanced features and functionality, and defect fixes.
The following is a list of enhancements implemented in Rapid Recovery release 6.0.2.
Additionally, release 6.0.x brought many other enhancements from release 5.4.x, such as rebranding from AppAssure to Rapid Recovery. Other changes included UI enhancements; OS support changes for Windows and Linux agents; virtual export and virtual standby to Microsoft Hyper-V cluster-shared volumes (CSV) running Windows Server 2012 or Windows Server 2012 R2 machines; importing archives on a schedule; and more. For detailed information on these changes, see Rapid Recovery 6.0.1 Release Notes.
The release is localized to the following languages: Chinese (Simplified), French, German, Japanese, Korean, Portuguese (Brazil), Spanish.
Recovery point data are stored in Recovery Point File System (RPFS) files in the repository. When you manually specify the deletion of a recovery point, or when the Core enforces rollup to merge or delete a recovery point, the specified recovery points are marked for deletion. This action creates a "Deleting of Index RPFS File" job on the Core. The relevant recovery points are immediately removed from the Core Console user interface.
The deletion job is immediately queued and then starts running in the background, concurrent with other Core operations. Deletion of recovery points is a processor-intensive task that may take hours. This delay in the removal of marked recovery points is known as the deferred delete feature of Rapid Recovery Core. This feature was first introduced in AppAssure release 5.4.1.
In Core environments under heavy load (such as undersized Cores, or environments with slow network speeds or infrastructure) performance of transfer jobs can be slow when performed concurrently with deferred delete jobs.
As an enhancement in release 6.0.2, Core now includes a new Deferred Delete option in nightly jobs. This option controls a single parameter: the ability to configure a maximum execution time for deferred delete during nightly jobs. The new deferred delete nightly job option is disabled by default.
When this new option is enabled, then after other nightly jobs have completed, a "Deleting records previously flagged for deletion" job is given the highest priority on the Core. Any new jobs for transfer, replication, and so on are queued behind the deferred delete job. In this way, Core processing is dedicated to removing deferred delete jobs, which complete much more quickly since other jobs are not running. When all marked recovery points are deleted, or when the maximum execution time period specified has passed, nightly jobs are completed, and the Core resumes normal operations. Transfers and other operations resume, and deletion of any remaining marked recovery points continues as a background job.
The default period for the maximum execution time for deferred delete is four hours. You can customize this timeout threshold in hours and minutes, from a minimum of 5 minutes to a maximum of 23 hours and 59 minutes. The amount of time for dedicated deletions should be determined based on load on your Core and the number of recovery points that are typically in the queue to be deleted.
Dell recommends using the default setting for this option (disabled) unless you are encountering transfer performance issues related to queued recovery point deletions. If you enable this new option, Dell recommends reviewing your Core jobs to ensure most recovery points marked for deletion are removed from the repository within a one-week period. This approach helps to balance maximum transfer performance with maximum reclamation of repository space.
For more detailed information on deferred delete, see Dell Knowledge Base article 198715, Understanding Deferred Delete in Nightly Jobs.
In addition to the Linux operating systems supported since Rapid Recovery release 6.0.1, the following Linux operating systems are now supported for Rapid Recovery Agent:
For a full set of software requirements for Rapid Recovery Agent, including other supported Linux operating systems and distributions, see the topic Rapid Recovery Agent software requirements.
Rapid Recovery release 6.0.2 includes improved integration with the VMware Virtual Disk Development Kit (VDDK) for creating and accessing VMware virtual disk storage. Rapid Recovery calls to the VDDK application program interfaces (APIs) have been separated into a VMware Proxy Service. As a result, if an API hangs (such as if a requested connection is temporarily unavailable), the process is terminated, and a new VDDK wrapper process is started.
This enhancement increases the likelihood that slow-responding or failed VMware API calls can be retried and likely performed. This affects setting or customizing the VMware proxy service port; changing timeout settings for the proxy; restarting the proxy service; and cleaning up snapshots when a repository is full.
The following Microsoft operating systems have recently reached end-of-life (EOL) and are no longer supported by Dell:
EOL applies to any service pack and any edition of the specified operating systems. When operating systems achieve the EOL phase, the software manufacturer stops supporting it. As a result, Dell does not support operating systems that have reached EOL.
If you protect machines in an AppAssure or Rapid Recovery Core that use an OS that has reached EOL, you do so at your own risk. If you experience problems recovering data from these machines, addressing these issues is outside the scope or responsibility of Dell Support.
In release 6.0.x, Microsoft Windows® 10 support includes the following exceptions:
