Problem description
Backup and restores do not proceed beyond 0% with the VSS. The security ID structure is invalid.
The connection from the destination server to the Phoenix cloud is stable. You can verify this by attempting a Telnet connection using the guidelines in the reference article or by monitoring TCP/IP packets with a network monitoring tool.
Whenever a backup or restore is run, the job is stuck at 0% and does not proceed unless the job is canceled.
Phoenix logs show no trace.
Cause
Phoenix executables are not excluded from the Antivirus.

Resolution
Add the Phoenix executables in the exclusion list of the Antivirus present on the system and run the restores again.
📝 Note
Many times, excluding “ *.exe “ does not work, try to exclude the complete file or the path. If the backup/restore still does not work, try disabling the Antivirus on the server.
