Figure 36. Creating a new remote snapshot
Set the Recurrence time (in minutes, hours, days, or weeks).
4.
Consider the following:
– Ensure you leave enough time for the previous snapshot to complete.
– Ensure there is adequate storage space at both sites.
– Set a retention policy at the primary site based on a timeframe or snapshot count.
Select the Management Group for the remote snapshot.
5.
Create a remote volume as the destination for the snapshot.
6.
Based on the convention used in this document, name the target Remote-XPSP2-02.
Set the replication level of Remote-XPSP2-02
7.
Set the retention policy for the remote site. .
8.
Depending on the scheduled start time, replication may now commence.
The first remote snapshot copies all your data – perhaps many terabytes – to the remote cluster.
To speed up the process, you can carry out this initial push on nodes at the local site, then physically
ship these nodes to the remote site
After the initial push, subsequent remote snapshots are smaller – only transferring changes made since
the last snapshot – and can make efficient use of a high-latency, low-bandwidth connection.
The physical transfer of data – in this case, a storage cluster or SAN that may be carrying many terabytes of data – is known as sneakernetting.
