How To Backup to CIFS or NAS storages with SEPSesam
About
This manual shows you how to save your data to remote devices like NAS storages, which can export Volumes via CIFS Shares.
Prerequisites
SEP Sesam Service User
In order to be able to backup to CIFS shares the SEP Sesam Service has to run as local Administrator account. By default SEP Sesam is started as local system account, which does not have access to network drives.
The User which SEP Sesam uses can be changed in the services settings like shown here:
After changing the account please restart the service.
Logon with the username which you have just configured in the service settings and try accessing the share using the explorer via UNC Path like shown in this screenshot:
In this Example the storage we want to backup to is represented as "\\sepnap.sep.de\winfix$"
During acces with the Internet Explorer no username or password request for authentification should appear, otherwise sesam will have troubles accessing the network share.
