Effect of password protecting folders
« on: September 14, 2008, 07:01:36 AM »

I'm considering setting up usernames and passwords on my new DNS-321. I'm wondering if this will have a negative impact on backup performance. I happen to use SyncBackSE to backup, but suspect the issue is generic to any backup with username/passwords set.

Also, I wonder what is the recommended setting for Oplocks (yes/no) when backing up from Windows Vista. Right now it's set to the default No.

Setting up usernames & passwords should not adversely affect performance, although you could create a situation where the backup simply fails due to a lack of access, especially with Vista - the NAS uses linux and SAMBA to provide interoperability with Windows and there have been compatibility issues - there are work arounds but not being a Vista user, I can't be more specific.

Oplocks - or opportunistic locking should not be an issue for you on or off unless you are trying to access the file from multiple locations simultaneously - it's purpose is to prevent concurrent write access.

Thanks fordem. That's the feedback I was hoping for. Apparently, I got it set correctly after a few tries because SyncBackSE is now running backups with username/password in place.

Also, glad to hear Oplocks is not a factor. We could be running simultaneous backups from two Vista laptops, but writing to different folders on the same drive. Would that be an issue?

I would not expect it to - when I said concurrent write access, I meant to the same file.
