Sorry if I was not clear. I think you are missing the point - but I will answer your questions:-
Read only - No.
Access from explorer - Yes.
Password required from explorer - Yes (See below).
Create files/folders -Yes (See below).
Main computer = Quad Q6600. 4GB Ram. Win7 64bit. Gigabit ethernet connection through Gigabit switch to NAS. All Cat 6 cable.
I can use Comodo to backup to the NAS - but only to folders or shares which are NOT password protected.
However, each working share is password protected for obvious reasons. But what Comodo user guide says will happen, does not happen (at least for me). The guide says that if I choose to back up to another computer (or NAS) on the network, Comodo will ask me for the username and password - so that Comodo can gain access to that device. Comodo does not ask for the username and password. That window is skipped in the process.
My question is simple. How can Comodo gain access to the protected shares/folders if it does not ask for the necessary username and password?
I am evaluating alternative backup software. If I can't back up to password protected shares on the NAS, I can't use Comodo.
There is another issue - Speed.
I used Comodo to backup to an unprotected share. It took a long time to back up 120GB. When I tried to "recover" one small pdf, it took 4 hours. So I think, I will not be able to use Comodo anyway!
Thanks for your support.
