Data Policies
Data Replication Rules
Data policies may also contain data replication rules. The BlackPearl system supports
replicating data to the following targets:
• BlackPearl target — A BlackPearl system remote to the local system that stores replicated
data.
• Amazon S3 target — An AWS S3 instance remote to the BlackPearl system that stores
replicated data.
• Microsoft Azure target— A Microsoft Azure instance remote to the BlackPearl system
that stores replicated data.
Tape Eject Strategy
A tape eject strategy must be considered as part of a data policy. Spectra recommends
keeping at least one copy of all archived data in the library at all times. Libraries can be
easily upgraded by purchasing more slot licenses, or, if the slots become completely full,
upgrading the library itself to one with more slots using the exclusive Spectra TranScale
technology.
A tape library user or administrator may decide to eject media cartridges from a tape library
for any of the reasons described below:
•
Ejecting a copy for off-site disaster recovery:
The BlackPearl system allows a user to
make multiple copies of data automatically. A typical use case is to create a “tape first
copy” that is intended to be left in the library for easy retrieval as well as an “eject copy”
intended to be removed from the library once full for archival at an alternate site for
safety. See
Configuring Advanced Bucket Management on page 100
for information on
setting up multiple copies and ejecting a copy, and the
for details
on the physical process of exporting and importing tapes into the library.
•
Ejecting a copy of data for transfer to another location:
In some work flows, a user ejects
a tape to transfer the data to another facility. Individual tapes can be ejected manually
using the BlackPearl user interface (see
).
•
Ejecting tapes to free up space in the library:
Some work flows and budgets require
older or unused media to be ejected, making it not readily available to the BlackPearl
system, in order to free up space in the tape library. After tapes are exported, new tapes
are imported to provide the BlackPearl system with new media for storage operations.
