Directory/File Based
Replication

OpenStorage (OST)

Quantum DXi4500 User's Guide
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
Based Replication Configuration
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
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
