Accessing Snapshots • Creating a RAID Group - When two RAIDS are grouped, their snapshot pools are added together. For example, if RAID A with a snapshot pool of 50 MB is grouped with RAID B with a snapshot pool of 25 MB, the resulting RAID Group will have a snapshot pool or 75 MB. Depending on the purpose you had in mind when grouping the RAIDs, the result of combining the two snapshot pools may or may not be desirable, and you will need to readjust the size as described above. Accessing Snapshots Snapshots are accessed via a snapshot share. Just as a share provides access to a portion of a live volume (or file system), a snapshot share provides access to the same portion of the file system on all current snapshots of the volume. The snapshot share's path into snapshots mimics the original share's path into the live volume. Creating a Snapshot Share You create a snapshot share by selecting the Create Snapshot Share option in the course of creating a live-volume share. For example, assume you create a share to a directory called "sales," and you select the Create Snapshot Share option. When you connect to the server via Internet Explorer or other file browser, two shares display: SALES SALES_SNAP The first share provides access to the live volume, and the second share provides access to any archived snapshots. Other than read-write settings (snapshots are read-only), a snapshot share inherits access privileges from its associated livevolume share. Tip The same folders appear on the Web View screen when you connect to Snap Server using a Web browser; however, the snapshot share folder does not provide access to the snapshot; it will always appear to be empty. You can prevent the snapshot share from displaying on this Web View screen by selecting the Hide Snapshot Share option when creating or editing a share. 58 Snap Server Administrator Guide

Creating a RAID Group —
When two RAIDS are grouped, their snapshot pools
are added together. For example, if RAID A with a snapshot pool of 50 MB is
grouped with RAID B with a snapshot pool of 25 MB, the resulting RAID Group
will have a snapshot pool or 75 MB. Depending on the purpose you had in mind
when grouping the RAIDs, the result of combining the two snapshot pools may
or may not be desirable, and you will need to readjust the size as described
above.
Accessing Snapshots
Snapshots are accessed via a snapshot share. Just as a share provides access to a
portion of a live volume (or file system), a snapshot share provides access to the
same portion of the file system on all current snapshots of the volume. The snapshot
share’s path into snapshots mimics the original share’s path into the live volume.
Creating a Snapshot Share
You create a snapshot share by selecting the
Create Snapshot Share
option in the
course of creating a live-volume share. For example, assume you create a share to a
directory called “sales,” and you select the
Create Snapshot Share
option. When you
connect to the server via Internet Explorer or other file browser, two shares display:
SALES
SALES_SNAP
The first share provides access to the live volume, and the second share provides
access to any archived snapshots. Other than read-write settings (snapshots are
read-only), a snapshot share inherits access privileges from its associated live-
volume share.
Tip
The same folders appear on the Web View screen when you connect to Snap
Server using a Web browser; however, the snapshot share folder does not provide
access to the snapshot; it will always appear to be empty. You can prevent the
snapshot share from displaying on this Web View screen by selecting the
Hide
Snapshot Share
option when creating or editing a share.
