Restrictions using Microsoft DFS from the NSS
To use DFS folders from the NSS, it is important to understand the limitations or restrictions involved and how to best configure your system:
•User Credentials must be Recognized by the Remote Server:
•Windows Operating System Version: MSDFS is not supported by Windows 98 clients.
•Windows Clients must be Restarted: After you set up a DFS root, any Windows clients that were connected must be restarted.
Step 11: Create a Snapshot for a Volume
As part of your backup strategy, you can configure the NSS6000 series NAS to capture snapshots of the data stored on a volume. You can define a snapshot to occur at various frequencies (such as hourly, daily, weekly, and so on). Individual snapshots are overwritten by the subsequent snapshot for the same interval. For example, if you set up an hourly snapshot, the 10:00 a.m. snapshot is replaced by the 11:00 a.m. snapshot (and so on). You can also configure multiple snapshots for the same volume. For example, you might set up an hourly snapshot, another snapshot to occur every four hours, and a daily snapshot. Each of these three snapshots is maintained separately and is only overwritten by the subsequent snapshot of its own frequency type. The snapshot(s) reside in the reserve area allocated for each snapshot. When a snapshot is created, the end user can access it by logging into the NSS with their username and password. Each snapshot appears as a copy of the share accessible by the end user.
The snapshot reserve is the amount of space that you want to allocate on the array to the snapshot. Once set, this space is not available for other storage use. The recommended amount of a reserve is generally between 10 to 20% of the total volume size. Note that if the period of time between
