We are implementing same solutin in our environment. Please let me know if I change the Netbackup logon service to some AD account and after sometime if AD account is expired, can we still be able to restore the backed up data through some other AD account which is having Read/Write permissions on filer ? Also, AD accounts passwords are tend to change regularly. If a password expires, it will become a tedious process to change the same in each and every server if this is implemented across the environment. Is there any alternative for this ?
