in instances where the IDB service fails to start for example after an upgrade and a manual atempt to start the service
ex;
D:\Omniback\idb\bin>pg_ctl.exe start –D “d:\Omniback\server\db80\pg
reports the following:
PANIC: could not open control file "Global/pg_control" Permission Denied.
check the PG_logs (ProgramData/omniback/Server/DB80/PG/PG_log) (/Var/opt/omni/server/db80/pg/pg_log)
should you see the following entry or similiar.

rin this scenario emoving the file "backup_label" resolved the issue and the IDB service was able to start.
