•

Instant recovery with a new domain in the case of a ransomware attack on your existing domain.

•

Cross-tenant restores, which you can use in cases of mergers and acquisitions. For more information about cross-tenant relocation, see The mailbox is restored with its new name to the original location as a subset of the original mailbox..

Improving backup and restore performance by modifying parameters in the configuration file

If you want to manage the performance of backup and restore jobs for Microsoft Outlook, SharePoint Online, Teams, and OneDrive accounts, you can modify the following parameters in the “nvoffice.cfg” file. The default location of this file is C:\Program Files\Quest\NetVault\config.

The values that you use depend on the value that you select for the Enable multi-streaming options for backup and restore jobs, as well as the bandwidth supported by your network.

The following tables list the parameters, their default settings, and a description of their impact.

Table 1. Parameters supported for network resilience
Parameter	Default	Description
Resiliency:Retry Count	3	Indicates the number of times that the plug-in runs GRAPH API after a failure occurs.
Resiliency:Retry Delay	5 (in seconds)	Indicates how long the plug-in should wait before running GRAPH API again after a failure occurs.

Table 2. Parameters supported for Outlook
Parameter	Default	Description
MsOutlook:Mails Without Attachment	1000	Indicates the number of email messages that one GRAPH API call can fetch of emails that do not have attachments. The 1000 value is the maximum allowed.
MsOutlook:Mails With Attachment	10	Indicates the number of email messages that one GRAPH API call can fetch of emails that have attachments. You can increase this value to increase the data-transfer rate, depending on the size of the attachments and network bandwidth.
MsOneDrive:Restore Chunk Size	5 (in MB)	Indicates the Chunk Size that can be used to restore — upload — mail attachments and attachments of type Event in chunks over OneDrive. The Chunk Size must be a multiple of 320 KiB (327,680 bytes). Using a Chunk Size that does not divide evenly by 320 KiB results in errors when committing some the files. You can increase this value to increase the data-transfer rate, depending on the network bandwidth. If you exceed a supported rate, the GRAPH API might generate a TIMEOUT exception.

Table 3. Parameters supported for OneDrive
Parameter	Default	Description
