If the NAS is on another machine in the network, you must use a UNC (uniform naming convention) path in the following format to connect to it:
You do not specify the drive name in the UNC path; instead, you merely create a folder in the desired drive and specify the folder name in the path. The computer_name stands for the name of the machine with the NAS (this can be an IP address if you prefer). The folder_name_in_drive stands for the folder in the drive. You must make sure that the share permissions and security groups declared for this folder contain administrative access on the server and have full control permissions (right-click on the folder on the NAS machine to view its properties). Please note that the folder should be shared manually before it can be used by the Recovery Solution.
If you believe you have done everything correctly, verify this by going to Control Panel > Administrative Tools > Services > Altiris Recovery Solution Server Service and seeing if the "Log On As" column entry contains the same value as you have specified for the NAS folder.
In order to use a network storage location for protected data, you must change the properties of the services on the server:
