Chapter 6: DXi4000 Replication
Performing Data Replication
86 Quantum DXi4000 User’s Guide
Caution: If you do not configure a replication schedule or manually
replicate the share on a regular basis, your data is
not
protected. While the DXi4000 continually sends data to the
target system in the background to optimize the
replication process, a snapshot that preserves the complete
structure of your data is sent to the target system
only
when a scheduled or manual replication job occurs. If you
do not regularly and frequently replicate your data as
described in Step 6 above, it cannot be restored at a later
time.
Task Overview: Setting
Up and Performing
Directory/File Based
Replication
To automatically replicate directories and files from a source system and
immediately recover them for use on a target system:
1 Perform the following steps on the target system:
a Add the source system to the list of allowed replication sources
(see Replication Receive on page 157).
b Create a new share with deduplication enabled (see Adding a
NAS Share on page 140).
c Enable Directory/File Based Replication for the new share and
specify the Sync ID (see Configuring a Target Share for Directory/
File Based Replication on page 107).
2 Perform the following steps on the source system:
a Specify the target system that will receive replicated data (see
Replication Send on page 155).
b Create a new share with deduplication enabled (see Adding a
NAS Share on page 140).
c Enable Directory/File Based Replication for the new share and
specify the Sync ID (see Configuring a Source Share for
Directory/File Based Replication on page 93).
A file is automatically replicated when it is closed or a period of time
after it is modified. After replication, the replicated directories and files
are immediately available on the target system. There is no need to
recover the share to make the directories and files available.
