Snapshot-on-the-box (QSnap) is a fully usable copy of a defined collection of data
that contains an image of the data as it appeared at the point in time, which means a
point-in-time data replication. It provides consistent and instant copies of data volumes
without any system downtime. Snapshot-on-the-box can keep up to 32 snapshots for one
logical volume. Rollback feature is provided for restoring the previous-snapshot data easily
while continuously using the volume for further data access. The data access which
includes read / write is working as usual without any impact to end users. The "on-the-
box" implies that it does not require any proprietary agents installed at host side. The
snapshot is taken at target side. It will not consume any host CPU time thus the server is
dedicated to the specific or other application. The snapshot copies can be taken manually
or by schedule every hour or every day, depends on the modification.
QSAN subsystem is the most cost-effective disk array system with completely integrated
high-performance and data-protection capabilities which meet or exceed the highest
industry standards, and
the best data solution for small / medium business (SMB)
users.
