Directory/File Based
Replication
Directory/File Based Replication
, when configured, automatically
replicates file data without user intervention or a schedule. The
replication is “triggered” by a CLI command for file data (NAS share).
This greatly enhances replication performance since only the file or
directory specifically mentioned in the command is replicated.
After a
Directory/File Based Replication
, NAS share files are
automatically
Recovered
on the target system. You may also initiate a
synchronization from the
Source
system to the
Target
system on NAS
shares that have been configured for
Directory/File Based Replication
.
This will replace all files on the
Target
NAS share with the most up-to-
date files on the
Source
system.
Directory/File Based Replication Process
The process for directory/file based replication is as follows:
1 Directory/File Based Replication
is configured on both the
Source
and
Target
. Configuring the directory/file based replication consists
of enabling
Directory/File Based Replication
on both the source
and target systems and setting the Sync ID. The Sync ID is used to
identify the corresponding target share that will receive the data
replicated from this source share (see
Source Role NAS Directory/File
Based Replication Configuration
on page 145 for more
information).
2
Data is backed up to the NAS share.
3
A post backup script is executed that triggers the replication of
specified files or directories in the NAS share.
Note:
For examples of post backup scripts, see
Replication Post Backup Scripts
OpenStorage (OST)
For Symantec NetBackup and Backup Exec users with specific versions of
the software, another replication option is available for DXi4500 models
through the Symantec OpenStorage (OST) API. For more details, refer to
the
Quantum DXi-Series: Symantec Veritas NetBackup OST
Configuration Guide
(PN 6-66???) and
Quantum DXi-Series: Symantec
Backup Exec OST Configuration Guide
(PN 6-66910).
