Backup Strategy - American Megatrends StorTrends 3200i Install Manual

Backup strategy

This solution used RAID 5 for the backup-to-disk LUNs in order to maximize
space and provide single disk failure protection.
In today‟s information-centric world, any loss of data could incur heavy
financial penalties leave alone other inconveniences caused. Regularly
saving and protecting data has become mandatory and is no longer a luxury.
StorTrends iTX stack‟s space and performance efficient Redirect on Write
snapshots literally allow maintaining hundreds of low latency Point-in-Time
snapped images of volumes. VSS Hardware provider along with scheduled
snapshots provides a very tight integration with Exchange server. The
architectural excellence of iTX ensures that there is no additional degradation
with the usage of multiple snapshots.
Provision tracking feature of iTX ensures that the snapshots are extremely
space efficient. StorTrends iTX VSS scheduler allows up to 8 different
snapshot schedules. For example one can have 60 snapshots minutes apart,
24 hourly snapshots, 30 daily snapshots and 24 monthly snapshots. Figure 5
shows how with ease such schedules can be defined. A compaction module
running in the background recaptures space released by deleted snapshots
and provisions them back to the free storage pool. There is no a-priori
knowledge necessary about the space to be provisioned for snapshots. Thin
provisioning architecture automatically and intelligently manages all these
behind the scenes. Coupled with this, space tracking and alerting agent
inside the stack notifies the administrator should there be any need.
