Procedure to restore a SpamTitan appliance from a backup

Restore procedures.

1. Install the VM, give it the original IP address, DNS, and domain name.
2. Install the Original License File, or a new license, the backup does not contain the license.
3. Update the SpamTitan appliance to the same version as the last backup.
4. Restore the backup.
5. If the network address was not set to be the same you must do so, the backup does not contain the network interface information.
6. Replace the branding and report images, the backup does not contain any of the branding images.

 So the take away from this:

1. Make regular automated backups to an FTP server.
2. Keep a copy of the license key file.
3. Keep copies of corporate branding.

Hyper V role fails installation, requires multiple reboots.

Issue description:

Hyper V role installation fails, during start up and message shows up which states the role installation failed, and a rollback is occurring. 

Cause:

For me this was being caused by the system reserved partition (SRP). The SRP was in an offline state. 

Resolution:

I used DISKPART to bring the volume online, and to assign it a drive letter to hold it online. Also I turned Automount back on, it was previously disabled because it was causing the Dell DRAC firmware upgrade to fail. The role addition succeeded this time.

Backup - AOFO: Initialization failure on: "System?State". Advanced Open File Option used: Microsoft Volume Shadow Copy Service (VSS).

V-79-10000-11226 - VSS Snapshot error. The Microsoft Volume Shadow Copy Service (VSS) snapshot provider selected returned: "Unexpected provider error". Ensure that all provider services are enabled and can be started. Check the Windows Event Viewer for details.


Had this error start occurring with BUE 2010 R3 on my backup execution server itself. When I ran "vssadmin list writers" several writers were in an error & timed out [7] state. Issue was caused by there not being enough free space on the system volume to include a VSS snapshot of itself because the feature set of this server has grown so large including WDS, and iSCSI target.

Solution was to move the storage location for snapshots for the system volume to the C: drive.
