Synergy Of Components - HP StorageWorks 1500cs - Modular Smart Array Manual

Synergy of components

This solution uses proven, customer-accepted, fault-tolerant technology with the option to add
additional system and data reliability. There is no new technology to learn; it has the look and feel of
primary storage.
Implementing a mezzanine backup-restore solution adds flexibility and performance to an existing
data protection system. Using this solution in concert with existing backup tools, high-priority data can
be backed up and later restored without having to wait on tape mounts. In addition, the new backup
resources made available allow existing backup resources to support greater demands for storage
and speed.
Tape libraries continue to play a vital role by providing data archiving and retention capabilities.
These capabilities are critical to meet the growing requirements businesses face for retaining business
information. They also play an essential role in disaster recovery and in making systems disaster
tolerant.
Table 1 describes three scenarios to better meet data protection requirements when using mezzanine
storage.
Table 8. Scenarios for the mezzanine backup-restore solution
Scenario description Backup window impact
Full and incremental Backup window
backups to reduced as additional
MSA1500; offline backup resources are
backup to tape available
Improved reliability from
RAID-protected storage
Weekly full backup Backup window
to tape, daily reduced as additional
incremental backups backup resources are
to MSA1500 available
More frequent backup
for frequently changing
data, without changing
media
Full and incremental Multi-stream host
backups to backups to disk reduce
MSA1500 the backup window
(not recommended
for a full data
protection solution)
Restore time impact Best used for
Instant access for Operations with
single file restores a fixed backup
window requiring
all applications to
be backed up at
one time
Business-critical
data with zero
tolerance for tape
error handling
Instant access for Large sets of data
single file restores requiring frequent
file restores
Improved reliability
from RAID-protected
storage
Instant access for full Business requires
or file restores high data
reliability and
Improved reliability
instant data
from RAID-protected
recovery over
storage
short periods of
time
Notes
More efficient use of
backup window
Tape resources can
be used more hours
per day
Less administration
required for frequent
incremental backups
Large backup
window needed for
weekly full backups
to tape
Requirement of
additional processes
for disaster recovery
and any required
data archiving or
retention
