Why is the CertLog directory excluded?

Hello,

I'm backing up a Windows Server that is part of a PKI. Avamar is skipping an important directory that I want to have for possible future disaster recovery.

The directory is C:\Windows\System32\CertLog. This is not part of the exceptions in the data set. I do suspect there are some built-in exceptions of which I'm not aware.

I put an inclusion rule, but the directory was still excluded.

I appreciate your help!

Avamar honours the Windows "FilesNoToBackup" registry key as documented here:

https://docs.microsoft.com/en-us/windows/desktop/backup/registry-keys-for-backup-and-restore#filesnottobackup

The full path to the key is:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\BackupRestore\FilesNotToBackup

While any application can add entries to this exclude list, many / most of them are defaults built into the OS by Microsoft and there's probably a good reason the files are not being backed up. Modify these settings at your peril.
