SMB (CIF) with Healthcheck - Safe?

[BMcDuff]

Hi,

We use QNAP as iSCSI targets for our backup. VBR server has all the recommended precautions (non-domain, encrypted drive etc).

But I still really like the extra layer of protection of the VBR 2FA feature. However, this doesn't really help with our iSCSI backups as the volumes are mounted on the server independent of the VBR application. If we were using SMB (CIF) then, even if they breach the server itself, they would still need to get past the 2FA and into VBR to be able to delete the backups.

What I am wondering is to what extent does running Healthcheck daily help with identifying any possible backup corruption that may be caused by using the SMB protocol? We don't have the infrastructure to run SureBackup.

To the full extent.

However, if they breach the server , deleting backups from SMB share is just as simple because its credentials are stored in the VBR database.

If you want real protection, use immutable storage.

Thank you for the clarification and pointing out the flaw in my plan

Our scaleout backups are immutable and the idea was to use QuObjects on the QNAPs for the local backup but that app is a disaster. Now nobody wants to throw out several thousand dollars worth of NAS and spend more money on Linux servers...
