Task Overview: Setting
Up and Performing
Directory/File or
Cartridge Based
Replication
To automatically replicate files or cartridges 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 Adding a Replication Source on page 258).
b Create a new share or partition with deduplication enabled (see
Adding a NAS Share on page 207 or Adding a VTL Partition on
page 224).
c Enable Directory/File or Cartridge Based Replication for the new
share or partition and specify the Sync ID (see Configuring a
Target Share for Directory/File Based Replication on page 144 or
Configuring a Target Partition for Cartridge Based Replication on
page 158).
2 Perform the following steps on the source system:
a Specify the target system that will receive replicated data (see
Adding a Replication Target on page 251).
b Create a new share or partition with deduplication enabled (see
Adding a NAS Share on page 207 or Adding a VTL Partition on
page 224).
c Enable Directory/File or Cartridge Based Replication for the new
share or partition and specify the Sync ID (see Configuring
Directory/File or Cartridge Based Replication on page 127
A file is automatically replicated when it is closed or a period of time
after it is modified. A cartridge is automatically replicated after it is
unmounted. After replication, the replicated files or cartridges are
immediately available on the target system. There is no need to recover
the share or partition to make the files or cartridges available.
