How to Fix Veeam Active Directory Application-Aware Backup Failures with SentinelOne &Resolving VSS Errors

I am sharing with the community the procedure I followed to resolve the failure of the Application Aware backup  post-installation of Sentinel One.

• Exception procedure S1 VSS SafeBOOt Tamper Protection

Open Administrative CMD 

cd "C:\Program Files\SentinelOne\Sentinel Agent your-version"

sentinelctl unprotect -k "<passphrase>"



sentinelctl config -p agent.vssConfig.enableResearchDataCollectorVssWriter -v false -k""PASSPHRASE"



sentinelctl config -p agent.vssConfig.vssProtection -v false



sentinelctl config -p agent.vssSnapshots -v false



sentinelctl config -p agent.safeBootProtection -v false -k "PASSPHRASE"



sentinelctl config antiTamperingConfig.allowSignedKnownAndVerifiedToSafeBoot true -k "PASSPHRASE"

• delete shadow :

diskshadow

delete shadows all

Exit

• re-enable protection:

sentinelctl protect -k "<passphrase>"
