Hello,
we are getting a error 0x80070780 "couldn`t access file" when protecting a volume. I've checked eventlogs and dpm logs on the dpm and the fileserver. But I can't find a hint which file causes the error.
We are using dpm 2010 with latest hotfixes on a Server 2008r2 with dell ml6000 tape library. File Server is a Windows Storage Server 2008r2 with attached iscsi volumes from dell equallogic array. Groveler service is active on all volumes.
Protection group seems to be ok since it has 14 volumes to backup on the fileserver. All backups are successful except volume t:\. The Volumes is a about 2tb and all volumes together are about 40tb on this server. Backup runs for a about 4-5 hours and the fails with the described error.
I've also resetted ownership and permissions for domain admins and lokal admin with icacls for this volume. Without success
Do you guys can give me tip how to solve the issue or how to find the file causing the error.
greetings stefan
