NOTE:
All of the information on automigration also applies to replication except where specifically
dealing with physical tapes (e.g., ejecting media) and where noted. Otherwise, where the
information refers to physical cartridges, for replication assume virtual cartridges instead.
NOTE:
Replication is deduplication-enabled if you have purchased the appropriate replication
and deduplication licenses, and your backup ISVs and data types are supported for deduplication.
Check the Accelerated deduplication ISV support matrix at
if your system supports deduplication.
Tape Initialization
When you first configure deduplication-enabled replication on your VLS and set up an echo copy
pool to a LAN/WAN destination, the first round of data migration is not deduplicated because
there is not yet a set of backups on the target VLS to deduplicate against. Because the first full set
of backups can be very large, the VLS system includes a tape initialization process. You can
transport the first full set of backups to the target VLS using physical tapes rather than the network.
This tape initialization process is optional and must be enabled by the administrator when creating
the echo copy pool.
The tape initialization process works, very generally, like this:
1.
Set up the LAN/WAN replication target on the remote site
2.
Set up an echo copy pool on the source site
3.
Run a standard deduplication backup on the source site
4.
Export the full backup to physical tapes
5.
Transfer the physical tapes to the remote site
6.
Import data from the tapes onto the remote LAN/WAN replication target
Once the tape initialization process is complete, the automatic migration of deduplicated data
from the source site to the target site over the LAN/WAN begins. See
tapes for Tape Initialization" (page 59)

Connecting a Destination Library
Automigration requires one or more dedicated destination libraries to be connected to the VLS
device.
Supported Destination Library Configurations
Automigration is supported on:
HP MSL series tape libraries
HP EML series tape libraries or library partitions
