function Restore-CohesityFileV2 { <# .SYNOPSIS Restores the specified files or folders from a previous backup based on Cohesity V2 Rest APIs .DESCRIPTION Restores the specified files or folders from a previous backup based on Cohesity V2 Rest APIs This script offers the -noIndex ($isDirectory = $True) parameter If the VM is not indexed. In this case, Most of the time the file/folder requested to restore is from a job run that is still in the indexing process using V2 apis. Restore is throwing errors if the VM is not indexed while using Restore-CohesityFile cmdlet which is based on V1 apis If the VM files/folders are indexed properly then use the Restore-CohesityFile cmdlet directly .NOTES Published by Cohesity .LINK https://cohesity.github.io/cohesity-powershell-module/#/README .EXAMPLE Restore-CohesityFileV2 -sourceVM "SQL-UT-VM2" -targetVM "SQL-UT-VM2" -fileNames "C:\.rnd" -restorePath "C:\" -wait .EXAMPLE Restore-CohesityFileV2 -sourceVM "SQL-UT-VM2" -targetVM "SQL-UT-VMD2" -fileNames "C:\Users\" -restorePath "C:\temp\" -wait .EXAMPLE Restore-CohesityFileV2 -sourceVM "SQL-UT-VM2" -targetVM "SQL-UT-VM2" -fileNames "C:\.rnd" -restorePath "C:\" -taskName "Test_task" -wait #> [CmdletBinding(DefaultParameterSetName = "Default", SupportsShouldProcess = $True, ConfirmImpact = "High")] param ( [Parameter(Mandatory = $True)] # Name of the Source VM, the filles need to be picked up for restore [string]$sourceVM, [Parameter(Mandatory = $False)] # Name of the Target V, the files need to be restored [string]$targetVM, [Parameter(Mandatory = $False)] # One or more file paths to be restored [array]$fileNames, [Parameter(Mandatory = $False)] # Task name of the restore job [string]$taskName, [Parameter(Mandatory = $False)] # text file of file paths [string]$fileList, [Parameter(Mandatory = $False)] # UserName for VMTools, applicable only when restoreMethod selected as VMTools [string]$vmUser, [Parameter(Mandatory = $False)] # Password for vm tools, applicable only when restoreMethod selected as VMTools [string]$vmPwd, [Parameter(Mandatory = $False)] # Alternate path to restore files in the target VM [string]$restorePath, [Parameter(Mandatory = $False)][ValidateSet('ExistingAgent','AutoDeploy','VMTools')] # Different categories of the restore Job through different tools [string]$restoreMethod = 'ExistingAgent', [Parameter(Mandatory = $False)] # Wait for completion and report status.
