Just tried with backup-jobs, but maybe it is working with restore-sessions as well:

Hello Anandu,

There are different ways to get this information, yes:

• Veeam ONE, part of Veeam Availability Suite - https://helpcenter.veeam.com/docs/one/reporter/restore_operator_activity.html?ver=110
• Veeam Backup and Replication PowerShell - https://helpcenter.veeam.com/docs/backup/powershell/export-vbraudit.html?ver=110
• Veeam Backup and Replication API, I think this sessions one should include them as well - https://helpcenter.veeam.com/docs/backup/vbr_rest/reference/vbr-rest-v1-rev2.html?ver=110#operation/GetAllSessions
• Veeam Enterprise Manager, this might help - https://helpcenter.veeam.com/docs/backup/em/em_reports_audit.html?ver=110
• Veeam Enterprise Manager, this might help as well if using VEM - https://helpcenter.veeam.com/docs/backup/em/em_notifications_on_rest_ops.html?ver=110

I remember we have an specific Audit folder here C:\ProgramData\Veeam\Backup\Audit take a look.

Hope this helps

Maybe export logs could be useful in your case?
