Smarter Storage Utilization
|
|---|
|
A space saver
|
StorageTek Data SnapShot software makes instantaneous backups of your data without using additional physical storage or hardware, maximizing your existing storage capacity.
|
|
|
A cost saver
|
Your costs for CPU and channel utilization associated with data movement can drop significantly with StorageTek SnapShot software. You can make as many copies as you need, without the cost of traditional copies.
|
|
Powerful Data Protection
|
|---|
|
Immediate availability
|
Data is ready to share in seconds after a "snap" is taken. This helps you roll back to a more recent copy of the data in the event of a data corruption or loss. The net result is a reduced Recovery Point Objective (RPO).
|
|
|
Copy-on-write design
|
StorageTek DataSnapshot uses a copy on first-write design and moves only blocks that are updated. This reduces the amount of additional disk space required, even when many snapshot volumes are used. You can maintain multiple copies without multiplying the amount of disk space, saving money.
|
|
|
Flexible snapshot reserve space
|
You can select where you want to locate metadata and copy-on-write data, and you can change the space allocation during operations. Plus, you can react quickly to unplanned needs without service disruption, locating snapshot reserve space on the class of storage appropriate to the need, from fast Fibre Channel to low-cost SATA.
|
|
Application Flexibility
|
|---|
|
Read and write support
|
Snapshot volumes are mountable as read/write volumes, giving you flexibility to support a broad range of uses, from backup to application testing.
|
|
|
Disk mirroring
|
You can implement StorageTek Data SnapShot software with Shared Virtual Array (SVA) disk systems enabling non-disruptive, no-capacity data mirroring configurations in MVS environments.
|
|
|
Backup and restore
|
StorageTek Data SnapShot software creates backup copies on SVA disk systems in seconds. You can then move backup data to tape storage later.
|
|
|
Application development and testing
|
Snapshot software can be used with SVA disk systems to create instant, numerous, capacity-free test copies without disrupting online data use for concurrent test and development.
